== Hex Buffer ==<br />
<br />
=== 74HC4050 Hex Non-Inverting Buffer ===<br />
The 74HC4050 chip has an input protection structure that makes these chips ideal as logic level translators which convert high-level logic to a low-level logic while operating off the low-level logic supply.<br />
<br />
For example, 5V input pulse levels can be down-converted to 3.3V logic levels. These parts also can be used as simple buffers without level translation.<br />
<br />
The buffer on these chips is one way. I.e. the input voltage controls the output voltage. You cannot control the input from the output. This makes these chips ideal for logic level conversion when using the SPI bus, but they wont work for I2C as this requires bi-directional logic level conversion.<br />
<br />
The 74HC4050 is fabricated with high-speed silicon gate technology<br />
<br />
Supply Voltage Range: 2V to 7V<br />
Input Voltage Range: -0.5V to 16V<br />
Logic Case Style: DIP<br />
No. of Pins: 16<br />

'''Infrared Obstacle avoidance sensor''': one infrared transmitter and one receiver, the receiver can detect the distance to the obstacles as a analog value and LM393 collect and compare this analog value and output digital value.<br><br />
'''TCRT5000 Infrared sensor''': Same working principle as the infrared sensor above, but the transmitter and receiver is integrated. Performance is also better.<br><br />
'''Microphone sensor''': Sound is sensing by the microphone, and send to the LM393, the analog output is not supported for this one, but it still output the digital value to see if the sound is detected or not.<br><br />
'''Photosensitive photocell sensor''': Light intensity is sensed here by the photocell sensor, the sensor itself output the a analog value, and the LM393 IC here works same to generate a digital output.<br><br />
'''Soil Sensor''': The sensor itself detects the moisture of the soil, LM393 works same in this case.<br><br />
'''Water Drop sensor''': the water drop sensor board itself detects how many water drop on the board, when a certain value comparing to the potentiometer is reached, then the LM393 will be trigger in the same way.<br><br />
To see how to use LM393 IC, here is some schematics based on the sensors describe above, a lot of parts are the same, only a few parts changed around the sensor.<br><br />

'''Microphone sensor''': Sound is sensing by the microphone, and send to the LM393, the analog output is not supported for this one, but it still output the digital value to see if the sound is detected or not.<br><br />
'''Photosensitive photocell sensor''': Light intensity is sensed here by the photocell sensor, the sensor itself output the a analog value, and the LM393 IC here works same to generate a digital output.<br><br />
'''Soil Sensor''': The sensor itself detects the moisture of the soil, LM393 works same in this case.<br><br />
'''Water Drop sensor''': the water drop sensor board itself detects how many water drop on the board, when a certain value comparing to the potentiometer is reached, then the LM393 will be trigger in the same way.<br><br />
To see how to use LM393 IC, here is some schematics based on the sensors describe above, a lot of parts are the same, only a few parts changed around the sensor.<br><br />

Features:<br />
<br />
The DRV8825 stepper motor driver carrier is a breakout board for TI's DRV8825 microstepping bipolar stepper motor driver. The module has a pinout and interface that are nearly identical to those of our A4988 stepper motor driver board, so it can be used as a higher-performance drop-in replacement for those boards in many applications.<br><br />
<br><br />
The DRV8825 features adjustable current limiting, overcurrent and overtemperature protection, and six microstep resolutions (down to 1/32-step). It operates from 8.2 – 45 V and can deliver up to approximately 1.5 A per phase without a heat sink or forced air flow (rated for up to 2.2 A per coil with sufficient additional cooling).<br><br />
<br><br />
1)Simple step and direction control interface<br><br />
2)Six different step resolutions: full-step, half-step, 1/4-step, 1/8-step, 1/16-step, and 1/32-step<br><br />
3)Adjustable current control lets you set the maximum current output with a potentiometer, which lets you use voltages above your stepper motor's rated voltage to achieve higher step rates<br><br />
4)45 V maximum supply voltage<br><br />
5)Built-in regulator (no external logic voltage supply needed)<br><br />
6)Can interface directly with 3.3 V and 5 V systems<br><br />
7)Over-temperature thermal shutdown, over-current shutdown, and under-voltage lockout<br><br />
8)Short-to-ground and shorted-load protection<br><br />
9)4-layer, 2 oz copper PCB for improved heat dissipation<br><br />
10)Exposed solderable ground pad below the driver IC on the bottom of the PCB<br><br />
11)Module size, pinout, and interface match those of our A4988 stepper motor driver carriers in most respects (see the bottom of this page for more information)<br><br />
<br> <br />
This product is a carrier board or breakout board for TI’s DRV8825 stepper motor driver; we therefore recommend careful reading of the DRV8825 datasheet (1MB pdf) before using this product. This stepper motor driver lets you control one bipolar stepper motor at up to 2.2 A output current per coil (see the Power Dissipation Considerations section below for more information). Here are some of the driver’s key features:<br />
<br><br />
Simple step and direction control interface<br><br />
Six different step resolutions: full-step, half-step, 1/4-step, 1/8-step, 1/16-step, and 1/32-step<br><br />
Adjustable current control lets you set the maximum current output with a potentiometer, which lets you use voltages above your stepper motor’s rated voltage to achieve higher step rates<br><br />
Intelligent chopping control that automatically selects the correct current decay mode (fast decay or slow decay)<br />
45 V maximum supply voltage<br><br />
Built-in regulator (no external logic voltage supply needed)<br><br />
Can interface directly with 3.3 V and 5 V systems<br><br />
Over-temperature thermal shutdown, over-current shutdown, and under-voltage lockout<br><br />
Short-to-ground and shorted-load protection<br><br />
4-layer, 2 oz copper PCB for improved heat dissipation<br><br />
Exposed solderable ground pad below the driver IC on the bottom of the PCB<br><br />
Module size, pinout, and interface match those of our A4988 stepper motor driver carriers in most respects (see the bottom of this page for more information)<br><br />
We also carry a DRV8824 stepper motor driver carrier that can serve as a direct substitute for the DRV8825 carrier when using lower-current stepper motors. The DRV8824 can only deliver up to 0.75 A per coil without a heat sink (1.2 A max with proper cooling), but it has larger current-sense resistors that allow for better microstepping performance than the DRV8825 carrier at low currents. The only way to tell our DRV8824 carrier apart from the DRV8825 carrier is by the markings on the driver IC; if you have a mix of the two, you might consider marking them (there is a blank square on the bottom silkscreen you can use for this). For lower-voltage applications, consider our pin-compatible DRV8834 carrier, which works with motor supply voltages as low as 2.5 V.<br><br />

<p>There is a known non-linear relationship between the measured temperature and the NTC resistance value which exhibits, then measure the resistance value of the NTC temperature value can also be calculated in the measurement. Relationship between the resistance value of the NTC temperature values are as follows:<br />
</p><br />
<pre>Rt = R x e^[B x (1/T1-1/T2)]<br />
</pre><br />
<p>Where, Rt is thermistor resistance at temperature T1; R is the thermistor at room temperature T2 nominal resistance value; B value is an important parameter thermistor; T1 and T2 refers to the degree that is K Kelvin temperature, K degrees = 273.15 (absolute temperature) degrees Celsius.<br /><br />
</p><p>Calculated inverse relationship between thermistor temperature and resistance value are as follows:<br /><br />
</p><br />
<pre>T1=1/(ln(Rt/R) /B 1/T2 )<br />
</pre><br />
<p>Measure the resistance values are generally known to use a series resistor values and applying a voltage of known size, measured by dividing the value of the known resistance of the resistor, to calculate the measured resistance is obtained, as shown in Figure 3. Facilities plus excitation voltage Eb, the thermistor resistance is Rt, the series resistor is Rs, then dividing the value series resistor:<br />
</p><br />
<pre>Eout = Eb x Rs/(Rt Rs)<br />
</pre><br />
<p>In addition to the series measurement, there is a Wheatstone bridge measurement method, shown in Figure 4. Let bridge excitation voltage Eb, the thermistor resistance is Rt, the bridge resistor as R1, R2 and R3, the bridge output voltage is:<br />
</p><br />
<pre>out = Eb x R3/(Rt R3) – Eb x R2/(R1 R2) = Eb x [R3/(Rt R3) – R2/(R1 R2)]<br />

Features:<br />
<br />
The DRV8825 stepper motor driver carrier is a breakout board for TI's DRV8825 microstepping bipolar stepper motor driver. The module has a pinout and interface that are nearly identical to those of our A4988 stepper motor driver board, so it can be used as a higher-performance drop-in replacement for those boards in many applications.<br><br />
<br><br />
The DRV8825 features adjustable current limiting, overcurrent and overtemperature protection, and six microstep resolutions (down to 1/32-step). It operates from 8.2 – 45 V and can deliver up to approximately 1.5 A per phase without a heat sink or forced air flow (rated for up to 2.2 A per coil with sufficient additional cooling).<br><br />
<br><br />
1)Simple step and direction control interface<br><br />
2)Six different step resolutions: full-step, half-step, 1/4-step, 1/8-step, 1/16-step, and 1/32-step<br><br />
3)Adjustable current control lets you set the maximum current output with a potentiometer, which lets you use voltages above your stepper motor's rated voltage to achieve higher step rates<br><br />
4)45 V maximum supply voltage<br><br />
5)Built-in regulator (no external logic voltage supply needed)<br><br />
6)Can interface directly with 3.3 V and 5 V systems<br><br />
7)Over-temperature thermal shutdown, over-current shutdown, and under-voltage lockout<br><br />
8)Short-to-ground and shorted-load protection<br><br />
9)4-layer, 2 oz copper PCB for improved heat dissipation<br><br />
10)Exposed solderable ground pad below the driver IC on the bottom of the PCB<br><br />
11)Module size, pinout, and interface match those of our A4988 stepper motor driver carriers in most respects (see the bottom of this page for more information)<br><br />
<br> <br />
This product is a carrier board or breakout board for TI’s DRV8825 stepper motor driver; we therefore recommend careful reading of the DRV8825 datasheet (1MB pdf) before using this product. This stepper motor driver lets you control one bipolar stepper motor at up to 2.2 A output current per coil (see the Power Dissipation Considerations section below for more information). Here are some of the driver’s key features:<br />
<br><br />
Simple step and direction control interface<br><br />
Six different step resolutions: full-step, half-step, 1/4-step, 1/8-step, 1/16-step, and 1/32-step<br><br />
Adjustable current control lets you set the maximum current output with a potentiometer, which lets you use voltages above your stepper motor’s rated voltage to achieve higher step rates<br><br />
Intelligent chopping control that automatically selects the correct current decay mode (fast decay or slow decay)<br />
45 V maximum supply voltage<br><br />
Built-in regulator (no external logic voltage supply needed)<br><br />
Can interface directly with 3.3 V and 5 V systems<br><br />
Over-temperature thermal shutdown, over-current shutdown, and under-voltage lockout<br><br />
Short-to-ground and shorted-load protection<br><br />
4-layer, 2 oz copper PCB for improved heat dissipation<br><br />
Exposed solderable ground pad below the driver IC on the bottom of the PCB<br><br />
Module size, pinout, and interface match those of our A4988 stepper motor driver carriers in most respects (see the bottom of this page for more information)<br><br />
We also carry a DRV8824 stepper motor driver carrier that can serve as a direct substitute for the DRV8825 carrier when using lower-current stepper motors. The DRV8824 can only deliver up to 0.75 A per coil without a heat sink (1.2 A max with proper cooling), but it has larger current-sense resistors that allow for better microstepping performance than the DRV8825 carrier at low currents. The only way to tell our DRV8824 carrier apart from the DRV8825 carrier is by the markings on the driver IC; if you have a mix of the two, you might consider marking them (there is a blank square on the bottom silkscreen you can use for this). For lower-voltage applications, consider our pin-compatible DRV8834 carrier, which works with motor supply voltages as low as 2.5 V.<br><br />

<p>There is a known non-linear relationship between the measured temperature and the NTC resistance value which exhibits, then measure the resistance value of the NTC temperature value can also be calculated in the measurement. Relationship between the resistance value of the NTC temperature values are as follows:<br />
</p><br />
<pre>Rt = R x e^[B x (1/T1-1/T2)]<br />
</pre><br />
<p>Where, Rt is thermistor resistance at temperature T1; R is the thermistor at room temperature T2 nominal resistance value; B value is an important parameter thermistor; T1 and T2 refers to the degree that is K Kelvin temperature, K degrees = 273.15 (absolute temperature) degrees Celsius.<br /><br />
</p><p>Calculated inverse relationship between thermistor temperature and resistance value are as follows:<br /><br />
</p><br />
<pre>T1=1/(ln(Rt/R) /B 1/T2 )<br />
</pre><br />
<p>Measure the resistance values are generally known to use a series resistor values and applying a voltage of known size, measured by dividing the value of the known resistance of the resistor, to calculate the measured resistance is obtained, as shown in Figure 3. Facilities plus excitation voltage Eb, the thermistor resistance is Rt, the series resistor is Rs, then dividing the value series resistor:<br />
</p><br />
<pre>Eout = Eb x Rs/(Rt Rs)<br />
</pre><br />
<p>In addition to the series measurement, there is a Wheatstone bridge measurement method, shown in Figure 4. Let bridge excitation voltage Eb, the thermistor resistance is Rt, the bridge resistor as R1, R2 and R3, the bridge output voltage is:<br />
</p><br />
<pre>out = Eb x R3/(Rt R3) – Eb x R2/(R1 R2) = Eb x [R3/(Rt R3) – R2/(R1 R2)]<br />

Features:<br />
<br />
The DRV8825 stepper motor driver carrier is a breakout board for TI's DRV8825 microstepping bipolar stepper motor driver. The module has a pinout and interface that are nearly identical to those of our A4988 stepper motor driver board, so it can be used as a higher-performance drop-in replacement for those boards in many applications.<br><br />
<br><br />
The DRV8825 features adjustable current limiting, overcurrent and overtemperature protection, and six microstep resolutions (down to 1/32-step). It operates from 8.2 – 45 V and can deliver up to approximately 1.5 A per phase without a heat sink or forced air flow (rated for up to 2.2 A per coil with sufficient additional cooling).<br><br />
<br><br />
1)Simple step and direction control interface<br><br />
2)Six different step resolutions: full-step, half-step, 1/4-step, 1/8-step, 1/16-step, and 1/32-step<br><br />
3)Adjustable current control lets you set the maximum current output with a potentiometer, which lets you use voltages above your stepper motor's rated voltage to achieve higher step rates<br><br />
4)45 V maximum supply voltage<br><br />
5)Built-in regulator (no external logic voltage supply needed)<br><br />
6)Can interface directly with 3.3 V and 5 V systems<br><br />
7)Over-temperature thermal shutdown, over-current shutdown, and under-voltage lockout<br><br />
8)Short-to-ground and shorted-load protection<br><br />
9)4-layer, 2 oz copper PCB for improved heat dissipation<br><br />
10)Exposed solderable ground pad below the driver IC on the bottom of the PCB<br><br />
11)Module size, pinout, and interface match those of our A4988 stepper motor driver carriers in most respects (see the bottom of this page for more information)<br><br />
<br> <br />
This product is a carrier board or breakout board for TI’s DRV8825 stepper motor driver; we therefore recommend careful reading of the DRV8825 datasheet (1MB pdf) before using this product. This stepper motor driver lets you control one bipolar stepper motor at up to 2.2 A output current per coil (see the Power Dissipation Considerations section below for more information). Here are some of the driver’s key features:<br />
<br><br />
Simple step and direction control interface<br><br />
Six different step resolutions: full-step, half-step, 1/4-step, 1/8-step, 1/16-step, and 1/32-step<br><br />
Adjustable current control lets you set the maximum current output with a potentiometer, which lets you use voltages above your stepper motor’s rated voltage to achieve higher step rates<br><br />
Intelligent chopping control that automatically selects the correct current decay mode (fast decay or slow decay)<br />
45 V maximum supply voltage<br><br />
Built-in regulator (no external logic voltage supply needed)<br><br />
Can interface directly with 3.3 V and 5 V systems<br><br />
Over-temperature thermal shutdown, over-current shutdown, and under-voltage lockout<br><br />
Short-to-ground and shorted-load protection<br><br />
4-layer, 2 oz copper PCB for improved heat dissipation<br><br />
Exposed solderable ground pad below the driver IC on the bottom of the PCB<br><br />
Module size, pinout, and interface match those of our A4988 stepper motor driver carriers in most respects (see the bottom of this page for more information)<br><br />
We also carry a DRV8824 stepper motor driver carrier that can serve as a direct substitute for the DRV8825 carrier when using lower-current stepper motors. The DRV8824 can only deliver up to 0.75 A per coil without a heat sink (1.2 A max with proper cooling), but it has larger current-sense resistors that allow for better microstepping performance than the DRV8825 carrier at low currents. The only way to tell our DRV8824 carrier apart from the DRV8825 carrier is by the markings on the driver IC; if you have a mix of the two, you might consider marking them (there is a blank square on the bottom silkscreen you can use for this). For lower-voltage applications, consider our pin-compatible DRV8834 carrier, which works with motor supply voltages as low as 2.5 V.<br><br />

<p>There is a known non-linear relationship between the measured temperature and the NTC resistance value which exhibits, then measure the resistance value of the NTC temperature value can also be calculated in the measurement. Relationship between the resistance value of the NTC temperature values are as follows:<br />
</p><br />
<pre>Rt = R x e^[B x (1/T1-1/T2)]<br />
</pre><br />
<p>Where, Rt is thermistor resistance at temperature T1; R is the thermistor at room temperature T2 nominal resistance value; B value is an important parameter thermistor; T1 and T2 refers to the degree that is K Kelvin temperature, K degrees = 273.15 (absolute temperature) degrees Celsius.<br /><br />
</p><p>Calculated inverse relationship between thermistor temperature and resistance value are as follows:<br /><br />
</p><br />
<pre>T1=1/(ln(Rt/R) /B 1/T2 )<br />
</pre><br />
<p>Measure the resistance values are generally known to use a series resistor values and applying a voltage of known size, measured by dividing the value of the known resistance of the resistor, to calculate the measured resistance is obtained, as shown in Figure 3. Facilities plus excitation voltage Eb, the thermistor resistance is Rt, the series resistor is Rs, then dividing the value series resistor:<br />
</p><br />
<pre>Eout = Eb x Rs/(Rt Rs)<br />
</pre><br />
<p>In addition to the series measurement, there is a Wheatstone bridge measurement method, shown in Figure 4. Let bridge excitation voltage Eb, the thermistor resistance is Rt, the bridge resistor as R1, R2 and R3, the bridge output voltage is:<br />
</p><br />
<pre>out = Eb x R3/(Rt R3) – Eb x R2/(R1 R2) = Eb x [R3/(Rt R3) – R2/(R1 R2)]<br />

Features:<br />
<br />
The DRV8825 stepper motor driver carrier is a breakout board for TI's DRV8825 microstepping bipolar stepper motor driver. The module has a pinout and interface that are nearly identical to those of our A4988 stepper motor driver board, so it can be used as a higher-performance drop-in replacement for those boards in many applications.<br><br />
<br><br />
The DRV8825 features adjustable current limiting, overcurrent and overtemperature protection, and six microstep resolutions (down to 1/32-step). It operates from 8.2 – 45 V and can deliver up to approximately 1.5 A per phase without a heat sink or forced air flow (rated for up to 2.2 A per coil with sufficient additional cooling).<br><br />
<br><br />
1)Simple step and direction control interface<br><br />
2)Six different step resolutions: full-step, half-step, 1/4-step, 1/8-step, 1/16-step, and 1/32-step<br><br />
3)Adjustable current control lets you set the maximum current output with a potentiometer, which lets you use voltages above your stepper motor's rated voltage to achieve higher step rates<br><br />
4)45 V maximum supply voltage<br><br />
5)Built-in regulator (no external logic voltage supply needed)<br><br />
6)Can interface directly with 3.3 V and 5 V systems<br><br />
7)Over-temperature thermal shutdown, over-current shutdown, and under-voltage lockout<br><br />
8)Short-to-ground and shorted-load protection<br><br />
9)4-layer, 2 oz copper PCB for improved heat dissipation<br><br />
10)Exposed solderable ground pad below the driver IC on the bottom of the PCB<br><br />
11)Module size, pinout, and interface match those of our A4988 stepper motor driver carriers in most respects (see the bottom of this page for more information)<br><br />
<br> <br />
This product is a carrier board or breakout board for TI’s DRV8825 stepper motor driver; we therefore recommend careful reading of the DRV8825 datasheet (1MB pdf) before using this product. This stepper motor driver lets you control one bipolar stepper motor at up to 2.2 A output current per coil (see the Power Dissipation Considerations section below for more information). Here are some of the driver’s key features:<br />
<br><br />
Simple step and direction control interface<br><br />
Six different step resolutions: full-step, half-step, 1/4-step, 1/8-step, 1/16-step, and 1/32-step<br><br />
Adjustable current control lets you set the maximum current output with a potentiometer, which lets you use voltages above your stepper motor’s rated voltage to achieve higher step rates<br><br />
Intelligent chopping control that automatically selects the correct current decay mode (fast decay or slow decay)<br />
45 V maximum supply voltage<br><br />
Built-in regulator (no external logic voltage supply needed)<br><br />
Can interface directly with 3.3 V and 5 V systems<br><br />
Over-temperature thermal shutdown, over-current shutdown, and under-voltage lockout<br><br />
Short-to-ground and shorted-load protection<br><br />
4-layer, 2 oz copper PCB for improved heat dissipation<br><br />
Exposed solderable ground pad below the driver IC on the bottom of the PCB<br><br />
Module size, pinout, and interface match those of our A4988 stepper motor driver carriers in most respects (see the bottom of this page for more information)<br><br />
We also carry a DRV8824 stepper motor driver carrier that can serve as a direct substitute for the DRV8825 carrier when using lower-current stepper motors. The DRV8824 can only deliver up to 0.75 A per coil without a heat sink (1.2 A max with proper cooling), but it has larger current-sense resistors that allow for better microstepping performance than the DRV8825 carrier at low currents. The only way to tell our DRV8824 carrier apart from the DRV8825 carrier is by the markings on the driver IC; if you have a mix of the two, you might consider marking them (there is a blank square on the bottom silkscreen you can use for this). For lower-voltage applications, consider our pin-compatible DRV8834 carrier, which works with motor supply voltages as low as 2.5 V.<br><br />

<p>There is a known non-linear relationship between the measured temperature and the NTC resistance value which exhibits, then measure the resistance value of the NTC temperature value can also be calculated in the measurement. Relationship between the resistance value of the NTC temperature values are as follows:<br />
</p><br />
<pre>Rt = R x e^[B x (1/T1-1/T2)]<br />
</pre><br />
<p>Where, Rt is thermistor resistance at temperature T1; R is the thermistor at room temperature T2 nominal resistance value; B value is an important parameter thermistor; T1 and T2 refers to the degree that is K Kelvin temperature, K degrees = 273.15 (absolute temperature) degrees Celsius.<br /><br />
</p><p>Calculated inverse relationship between thermistor temperature and resistance value are as follows:<br /><br />
</p><br />
<pre>T1=1/(ln(Rt/R) /B 1/T2 )<br />
</pre><br />
<p>Measure the resistance values are generally known to use a series resistor values and applying a voltage of known size, measured by dividing the value of the known resistance of the resistor, to calculate the measured resistance is obtained, as shown in Figure 3. Facilities plus excitation voltage Eb, the thermistor resistance is Rt, the series resistor is Rs, then dividing the value series resistor:<br />
</p><br />
<pre>Eout = Eb x Rs/(Rt Rs)<br />
</pre><br />
<p>In addition to the series measurement, there is a Wheatstone bridge measurement method, shown in Figure 4. Let bridge excitation voltage Eb, the thermistor resistance is Rt, the bridge resistor as R1, R2 and R3, the bridge output voltage is:<br />
</p><br />
<pre>out = Eb x R3/(Rt R3) – Eb x R2/(R1 R2) = Eb x [R3/(Rt R3) – R2/(R1 R2)]<br />

Arduino Timeline <br />
</h2>But first&hellip;some history! First there was the serial Arduino (what&#39;s the name of it?) with RS232 which was not used outside of the Arduino team &amp; friends.<span>&nbsp;</span><br /><br />The first popularly manufactured Arduino was called the NG (New Generation, like Star Trek, yknow?) The NG used the Atmega8 chip running at 16 MHz and an FT232 chip for the USB interface. The bootloader takes up 2KB of space and runs at 19200 baud.<br /><br />The next version was the Diecimila. The Diecimila updated the chip from the Atmega8 to the Atmega168. The great thing here is double the space and memory (16K instead of 8K). It still ran at 16MHz. The Diecimila also added two extra header pins for 3.3V (from the FTDI chip) and the reset pin which can be handy when a shield is covering up the Reset button. The bootloader takes up 2KB of space and runs at 19200 baud. Auto-resetting was also added which makes life awesomer for everyone.<span>&nbsp;</span><br /><br />In 2009, the Duemilanove was released. This one also upgraded the chip again, to the Atmega328. Yet another doubling of space and memory! Another upgrade is now the power is automagically switched between USB and DC-jack which removed the previous jumper. This makes it easier and faster to move from programming to standalone and got rid of some confusion. The bootloader takes up 2KB of space and runs at 57600 baud. &nbsp;<br /><br />In 2010, we have the Uno! The Uno still uses the 328P chip and the power switcher. It has a smaller bootloader called OptiBoot (more space for users&#39; projects) that runs at 115K. So even though the chip is the same, you get another 1.5K of extra flash space that was previously used by the bootloader. The FTDI chip has also been replaced with a atmega8u2 which allows for different kinds of USB interfaces. Finally, there&#39;s an extra 3.3V regulator (LP2985) for a better 3.3V supply. whew!</div><div class="row-fluid build-text" style="box-sizing: border-box; padding-bottom: 20px"><h2 style="box-sizing: border-box; font-family: &quot;Gotham SSm A&quot;,&quot;Gotham SSm B&quot;,Montserrat,&quot;Lucida Grande&quot;,&quot;Lucida Sans Unicode&quot;,&quot;Lucida Sans&quot;,Geneva,Verdana,sans-serif; font-weight: 400; line-height: 1; color: inherit; margin: 10px 0px 0px; font-size: 21px; padding-bottom: 5px"><a style="box-sizing: border-box; background: transparent none repeat scroll 0% 0%; color: #999999; text-decoration: none; position: absolute; display: inline-block; margin-top: 3px; left: -17px; font-size: 14px" href="https://learn.adafruit.com/arduino-tips-tricks-and-techniques/arduino-uno-faq#new-usb-chip" class="anchor-link"><span class="fa fa-link" style="box-sizing: border-box; display: inline-block; font-style: normal; font-variant: normal; font-weight: normal; font-stretch: normal; line-height: 1; font-family: FontAwesome; font-size: inherit; text-rendering: auto"></span></a><span class="anchor-link-target" style="box-sizing: border-box"></span>New USB Chip</h2><span style="box-sizing: border-box">So! All of the older Arduinos (NG, Diecimila and Duemilanove) have used an FTDI chip (the FT232RL) to convert the TTL serial from the Arduino chip (Atmel ATmega). This allows for printable debugging, connecting to software like PureData/Max, Processing, Python, etc. etc. It also allows updating the firmware via the serial bootloader.<br /></span><br /><span style="box-sizing: border-box">The good news about the FT232RL has royalty-free drivers and pretty much just works. The bad news is that it can -only- act as a USB/Serial port. It can&#39;t act like a keyboard, mouse, disk drive, MIDI device, etc.</span><br /></div><div class="row-fluid build-image" style="box-sizing: border-box; position: relative; padding-bottom: 20px"><a style="box-sizing: border-box; background: transparent none repeat scroll 0% 0%; color: #00a7e9; text-decoration: none; position: relative; display: block" href="https://learn.adafruit.com/assets/3237"><img style="box-sizing: border-box; border: 0px none; vertical-align: middle; display: block; max-width: 100%; height: auto; margin: 0px auto; text-align: center" class="3237-asset img-responsive" src="https://cdn-learn.adafruit.com/assets/assets/000/003/237/medium800/learn_arduino_atmega8u2.jpg?1396794424" alt="learn_arduino_atmega8u2.jpg" /></a></div><div class="row-fluid build-text" style="box-sizing: border-box; padding-bottom: 20px"><span style="box-sizing: border-box">The Uno has changed that by exchanging the FT232RL chip with an atmega8u2 chip. There are a few things that are possible with this new chip but before we discuss that lets make it clear that by default, this chip acts identically to the FTDI chip that it replaces. It&#39;s just a USB-serial port!<br /><br /></span><span style="box-sizing: border-box">One improvement in updating the chip is that, previously, Mac users needed to install FTDI drivers. The 8u2 imitates a &#39;generic&#39; CDC serial device. So now, Mac users do not have to install a driver. Windows users still need to install the .INF file but luckily there are no drivers. This means there will be fewer problems with new versions of windows. There is no way to have a serial USB device that doesn&#39;t require an INF file in windows, sadly :(<br /></span><br />The big thing that is nice about the 8u2 is that<span>&nbsp;</span><strong style="box-sizing: border-box; font-weight: bold">advanced</strong><span style="box-sizing: border-box"><span>&nbsp;</span>users can turn it into a different kind of USB device. For example it can act like a keyboard or mouse. Or a disk driver. Or a MIDI interface, etc. Right now there are no examples of how to do this, but we hope to post some shortly.<br /></span><br />And, finally, going with the 8u2 reduced the price of the board which made up for some of the other extras.<br /></div><div class="build-faq" style="box-sizing: border-box; padding-bottom: 20px"><h2 style="box-sizing: border-box; font-family: &quot;Gotham SSm A&quot;,&quot;Gotham SSm B&quot;,Montserrat,&quot;Lucida Grande&quot;,&quot;Lucida Sans Unicode&quot;,&quot;Lucida Sans&quot;,Geneva,Verdana,sans-serif; font-weight: bold; line-height: 16px; color: inherit; margin: 10px 0px 0px; font-size: 16px; padding: 0px 0px 5px" class="question"><a style="box-sizing: border-box; background: transparent none repeat scroll 0% 0%; color: #999999; text-decoration: none; position: absolute; display: inline-block; margin-top: 3px; left: -17px; font-size: 14px" href="https://learn.adafruit.com/arduino-tips-tricks-and-techniques/arduino-uno-faq#faq-9" class="anchor-link"><span class="fa fa-link" style="box-sizing: border-box; display: inline-block; font-style: normal; font-variant: normal; font-weight: normal; font-stretch: normal; line-height: 1; font-family: FontAwesome; font-size: inherit; text-rendering: auto"></span></a><span class="anchor-link-target" style="box-sizing: border-box"></span>Why not just go with a atmega32u4?</h2><div class="answer" style="box-sizing: border-box; padding-left: 20px; margin: 0px">The Arduino team has indicated they thought about this but preferred that hackability of a DIP chip.<span>&nbsp;</span><br /><br />Right now there are a few Arduino&#39;s with a 32u4 chip such as the Leonardo, Micro and Esplora<br /></div></div><div class="build-faq" style="box-sizing: border-box; padding-bottom: 20px"><h2 style="box-sizing: border-box; font-family: &quot;Gotham SSm A&quot;,&quot;Gotham SSm B&quot;,Montserrat,&quot;Lucida Grande&quot;,&quot;Lucida Sans Unicode&quot;,&quot;Lucida Sans&quot;,Geneva,Verdana,sans-serif; font-weight: bold; line-height: 16px; color: inherit; margin: 10px 0px 0px; font-size: 16px; padding: 0px 0px 5px" class="question"><a style="box-sizing: border-box; background: transparent none repeat scroll 0% 0%; color: #999999; text-decoration: none; position: absolute; display: inline-block; margin-top: 3px; left: -17px; font-size: 14px" href="https://learn.adafruit.com/arduino-tips-tricks-and-techniques/arduino-uno-faq#faq-10" class="anchor-link"><span class="fa fa-link" style="box-sizing: border-box; display: inline-block; font-style: normal; font-variant: normal; font-weight: normal; font-stretch: normal; line-height: 1; font-family: FontAwesome; font-size: inherit; text-rendering: auto"></span></a><span class="anchor-link-target" style="box-sizing: border-box"></span>How can I change the USB firmware?</h2><div class="answer" style="box-sizing: border-box; padding-left: 20px; margin: 0px">The 8u2 can be programmed by soldering a 6-pin ISP header (the R3 has the 6-pin header pre-soldered in) and using a standard AVR programmer. You can also use the bootloader (DFU) in the 8u2. On first generation Unos, you enable this by soldering the 10K resistor right underneath the board. (R2 and R3 versions of the Uno use the 16U2 and do not require the resistor!) Again, we don&#39;t have any examples or tutorials but hope to shortly.</div></div><div class="row-fluid build-image" style="box-sizing: border-box; position: relative; padding-bottom: 20px"><a style="box-sizing: border-box; background: transparent none repeat scroll 0% 0%; color: #00a7e9; text-decoration: none; position: relative; display: block" href="https://learn.adafruit.com/assets/3238"><img style="box-sizing: border-box; border: 0px none; vertical-align: middle; display: block; max-width: 100%; height: auto; margin: 0px auto; text-align: center" class="3238-asset img-responsive" src="https://cdn-learn.adafruit.com/assets/assets/000/003/238/medium800/learn_arduino_dfushort.jpg?1396794430" alt="learn_arduino_dfushort.jpg" /></a></div><div class="row-fluid build-image" style="box-sizing: border-box; position: relative; padding-bottom: 20px"><a style="box-sizing: border-box; background: transparent none repeat scroll 0% 0%; color: #00a7e9; text-decoration: none; position: relative; display: block" href="https://learn.adafruit.com/assets/3240"><img style="box-sizing: border-box; border: 0px none; vertical-align: middle; display: block; max-width: 100%; height: auto; margin: 0px auto; text-align: center" class="3240-asset img-responsive" src="https://cdn-learn.adafruit.com/assets/assets/000/003/240/medium800/learn_arduino_8u2isp.jpg?1396794440" alt="learn_arduino_8u2isp.jpg" /></a></div><div class="row-fluid build-text" style="box-sizing: border-box; padding-bottom: 20px"><span style="box-sizing: border-box; margin-bottom: 0px">The code for the 8u2 is based on LUFA, Dean Cameran&#39;s totally awesome USB-AVR library that has great examples and documentation.

Does the Uno use a resonator or a crystal <br />
for the processor clock?</h2><div class="answer" style="box-sizing: border-box; padding-left: 20px; margin: 0px"><span style="box-sizing: border-box">The FT232RL had an internal oscillator whereas the 8u2 does not. That means there is a 16mhz crystal next to the 8u2 to allow it to keep up with precise USB timing.<br /><br /></span>On the other hand, the Atmega328p chip that is the core processor in the Arduino now has a 16mhz ceramic resonator. Ceramic resonators are slightly less precise than crystals but we have been assured that this one was specified and works quite well.<br /></div></div><div class="row-fluid build-image" style="box-sizing: border-box; position: relative; padding-bottom: 20px"><a style="box-sizing: border-box; background: transparent none repeat scroll 0% 0%; color: #00a7e9; text-decoration: none; position: relative; display: block" href="https://learn.adafruit.com/assets/3241"><img style="box-sizing: border-box; border: 0px none; vertical-align: middle; display: block; max-width: 100%; height: auto; margin: 0px auto; text-align: center" class="3241-asset img-responsive" src="https://cdn-learn.adafruit.com/assets/assets/000/003/241/medium800/learn_arduino_crystal.jpg?1396794446" alt="learn_arduino_crystal.jpg" /></a></div><div class="row-fluid build-image" style="box-sizing: border-box; position: relative; padding-bottom: 20px"><a style="box-sizing: border-box; background: transparent none repeat scroll 0% 0%; color: #00a7e9; text-decoration: none; position: relative; display: block" href="https://learn.adafruit.com/assets/3242"><img style="box-sizing: border-box; border: 0px none; vertical-align: middle; display: block; max-width: 100%; height: auto; margin: 0px auto; text-align: center" class="3242-asset img-responsive" src="https://cdn-learn.adafruit.com/assets/assets/000/003/242/medium800/learn_arduino_resonator.jpg?1396794453" alt="learn_arduino_resonator.jpg" /></a></div><div class="build-faq" style="box-sizing: border-box; padding-bottom: 20px"><h2 style="box-sizing: border-box; font-family: &quot;Gotham SSm A&quot;,&quot;Gotham SSm B&quot;,Montserrat,&quot;Lucida Grande&quot;,&quot;Lucida Sans Unicode&quot;,&quot;Lucida Sans&quot;,Geneva,Verdana,sans-serif; font-weight: bold; line-height: 16px; color: inherit; margin: 10px 0px 0px; font-size: 16px; padding: 0px 0px 5px" class="question"><a style="box-sizing: border-box; background: transparent none repeat scroll 0% 0%; color: #999999; text-decoration: none; position: absolute; display: inline-block; margin-top: 3px; left: -17px; font-size: 14px" href="https://learn.adafruit.com/arduino-tips-tricks-and-techniques/arduino-uno-faq#faq-17" class="anchor-link"><span class="fa fa-link" style="box-sizing: border-box; display: inline-block; font-style: normal; font-variant: normal; font-weight: normal; font-stretch: normal; line-height: 1; font-family: FontAwesome; font-size: inherit; text-rendering: auto"></span></a><span class="anchor-link-target" style="box-sizing: border-box"></span>So the Arduino is not as precise, timing-wise?</h2><div class="answer" style="box-sizing: border-box; padding-left: 20px; margin: 0px"><span style="box-sizing: border-box; margin-bottom: 0px">The short answer is: yes.

== Arduino Timeline == <br />
</h2>But first&hellip;some history! First there was the serial Arduino (what&#39;s the name of it?) with RS232 which was not used outside of the Arduino team &amp; friends.<span>&nbsp;</span><br /><br />The first popularly manufactured Arduino was called the NG (New Generation, like Star Trek, yknow?) The NG used the Atmega8 chip running at 16 MHz and an FT232 chip for the USB interface. The bootloader takes up 2KB of space and runs at 19200 baud.<br /><br />The next version was the Diecimila. The Diecimila updated the chip from the Atmega8 to the Atmega168. The great thing here is double the space and memory (16K instead of 8K). It still ran at 16MHz. The Diecimila also added two extra header pins for 3.3V (from the FTDI chip) and the reset pin which can be handy when a shield is covering up the Reset button. The bootloader takes up 2KB of space and runs at 19200 baud. Auto-resetting was also added which makes life awesomer for everyone.<span>&nbsp;</span><br /><br />In 2009, the Duemilanove was released. This one also upgraded the chip again, to the Atmega328. Yet another doubling of space and memory! Another upgrade is now the power is automagically switched between USB and DC-jack which removed the previous jumper. This makes it easier and faster to move from programming to standalone and got rid of some confusion. The bootloader takes up 2KB of space and runs at 57600 baud. &nbsp;<br /><br />In 2010, we have the Uno! The Uno still uses the 328P chip and the power switcher. It has a smaller bootloader called OptiBoot (more space for users&#39; projects) that runs at 115K. So even though the chip is the same, you get another 1.5K of extra flash space that was previously used by the bootloader. The FTDI chip has also been replaced with a atmega8u2 which allows for different kinds of USB interfaces. Finally, there&#39;s an extra 3.3V regulator (LP2985) for a better 3.3V supply. whew!</div><div class="row-fluid build-text" style="box-sizing: border-box; padding-bottom: 20px"><h2 style="box-sizing: border-box; font-family: &quot;Gotham SSm A&quot;,&quot;Gotham SSm B&quot;,Montserrat,&quot;Lucida Grande&quot;,&quot;Lucida Sans Unicode&quot;,&quot;Lucida Sans&quot;,Geneva,Verdana,sans-serif; font-weight: 400; line-height: 1; color: inherit; margin: 10px 0px 0px; font-size: 21px; padding-bottom: 5px"><a style="box-sizing: border-box; background: transparent none repeat scroll 0% 0%; color: #999999; text-decoration: none; position: absolute; display: inline-block; margin-top: 3px; left: -17px; font-size: 14px" href="https://learn.adafruit.com/arduino-tips-tricks-and-techniques/arduino-uno-faq#new-usb-chip" class="anchor-link"><span class="fa fa-link" style="box-sizing: border-box; display: inline-block; font-style: normal; font-variant: normal; font-weight: normal; font-stretch: normal; line-height: 1; font-family: FontAwesome; font-size: inherit; text-rendering: auto"></span></a><span class="anchor-link-target" style="box-sizing: border-box"></span>New USB Chip</h2><span style="box-sizing: border-box">So! All of the older Arduinos (NG, Diecimila and Duemilanove) have used an FTDI chip (the FT232RL) to convert the TTL serial from the Arduino chip (Atmel ATmega). This allows for printable debugging, connecting to software like PureData/Max, Processing, Python, etc. etc. It also allows updating the firmware via the serial bootloader.<br /></span><br /><span style="box-sizing: border-box">The good news about the FT232RL has royalty-free drivers and pretty much just works. The bad news is that it can -only- act as a USB/Serial port. It can&#39;t act like a keyboard, mouse, disk drive, MIDI device, etc.</span><br /></div><div class="row-fluid build-image" style="box-sizing: border-box; position: relative; padding-bottom: 20px"><a style="box-sizing: border-box; background: transparent none repeat scroll 0% 0%; color: #00a7e9; text-decoration: none; position: relative; display: block" href="https://learn.adafruit.com/assets/3237"><img style="box-sizing: border-box; border: 0px none; vertical-align: middle; display: block; max-width: 100%; height: auto; margin: 0px auto; text-align: center" class="3237-asset img-responsive" src="https://cdn-learn.adafruit.com/assets/assets/000/003/237/medium800/learn_arduino_atmega8u2.jpg?1396794424" alt="learn_arduino_atmega8u2.jpg" /></a></div><div class="row-fluid build-text" style="box-sizing: border-box; padding-bottom: 20px"><span style="box-sizing: border-box">The Uno has changed that by exchanging the FT232RL chip with an atmega8u2 chip. There are a few things that are possible with this new chip but before we discuss that lets make it clear that by default, this chip acts identically to the FTDI chip that it replaces. It&#39;s just a USB-serial port!<br /><br /></span><span style="box-sizing: border-box">One improvement in updating the chip is that, previously, Mac users needed to install FTDI drivers. The 8u2 imitates a &#39;generic&#39; CDC serial device. So now, Mac users do not have to install a driver. Windows users still need to install the .INF file but luckily there are no drivers.

You can also use the bootloader (DFU) in the 8u2. On first generation Unos, you enable this by soldering the 10K resistor right underneath the board. (R2 and R3 versions of the Uno use the 16U2 and do not require the resistor!) Again, we don&#39;t have any examples or tutorials but hope to shortly.</div></div><div class="row-fluid build-image" style="box-sizing: border-box; position: relative; padding-bottom: 20px"><a style="box-sizing: border-box; background: transparent none repeat scroll 0% 0%; color: #00a7e9; text-decoration: none; position: relative; display: block" href="https://learn.adafruit.com/assets/3238"><img style="box-sizing: border-box; border: 0px none; vertical-align: middle; display: block; max-width: 100%; height: auto; margin: 0px auto; text-align: center" class="3238-asset img-responsive" src="https://cdn-learn.adafruit.com/assets/assets/000/003/238/medium800/learn_arduino_dfushort.jpg?1396794430" alt="learn_arduino_dfushort.jpg" /></a></div><div class="row-fluid build-image" style="box-sizing: border-box; position: relative; padding-bottom: 20px"><a style="box-sizing: border-box; background: transparent none repeat scroll 0% 0%; color: #00a7e9; text-decoration: none; position: relative; display: block" href="https://learn.adafruit.com/assets/3240"><img style="box-sizing: border-box; border: 0px none; vertical-align: middle; display: block; max-width: 100%; height: auto; margin: 0px auto; text-align: center" class="3240-asset img-responsive" src="https://cdn-learn.adafruit.com/assets/assets/000/003/240/medium800/learn_arduino_8u2isp.jpg?1396794440" alt="learn_arduino_8u2isp.jpg" /></a></div><div class="row-fluid build-text" style="box-sizing: border-box; padding-bottom: 20px"><span style="box-sizing: border-box; margin-bottom: 0px">The code for the 8u2 is based on LUFA, Dean Cameran&#39;s totally awesome USB-AVR library that has great examples and documentation.

First there was the serial Arduino (what&#39;s the name of it?) with RS232 which was not used outside of the Arduino team &amp; friends.<span>&nbsp;</span><br /><br />The first popularly manufactured Arduino was called the NG (New Generation, like Star Trek, yknow?) The NG used the Atmega8 chip running at 16 MHz and an FT232 chip for the USB interface. The bootloader takes up 2KB of space and runs at 19200 baud.<br /><br />The next version was the Diecimila. The Diecimila updated the chip from the Atmega8 to the Atmega168. The great thing here is double the space and memory (16K instead of 8K). It still ran at 16MHz. The Diecimila also added two extra header pins for 3.3V (from the FTDI chip) and the reset pin which can be handy when a shield is covering up the Reset button. The bootloader takes up 2KB of space and runs at 19200 baud. Auto-resetting was also added which makes life awesomer for everyone.<span>&nbsp;</span><br /><br />In 2009, the Duemilanove was released. This one also upgraded the chip again, to the Atmega328. Yet another doubling of space and memory! Another upgrade is now the power is automagically switched between USB and DC-jack which removed the previous jumper. This makes it easier and faster to move from programming to standalone and got rid of some confusion. The bootloader takes up 2KB of space and runs at 57600 baud. &nbsp;<br /><br />In 2010, we have the Uno! The Uno still uses the 328P chip and the power switcher. It has a smaller bootloader called OptiBoot (more space for users&#39; projects) that runs at 115K. So even though the chip is the same, you get another 1.5K of extra flash space that was previously used by the bootloader. The FTDI chip has also been replaced with a atmega8u2 which allows for different kinds of USB interfaces. Finally, there&#39;s an extra 3.3V regulator (LP2985) for a better 3.3V supply. whew!</div><div class="row-fluid build-text" style="box-sizing: border-box; padding-bottom: 20px"><h2 style="box-sizing: border-box; font-family: &quot;Gotham SSm A&quot;,&quot;Gotham SSm B&quot;,Montserrat,&quot;Lucida Grande&quot;,&quot;Lucida Sans Unicode&quot;,&quot;Lucida Sans&quot;,Geneva,Verdana,sans-serif; font-weight: 400; line-height: 1; color: inherit; margin: 10px 0px 0px; font-size: 21px; padding-bottom: 5px"><a style="box-sizing: border-box; background: transparent none repeat scroll 0% 0%; color: #999999; text-decoration: none; position: absolute; display: inline-block; margin-top: 3px; left: -17px; font-size: 14px" href="https://learn.adafruit.com/arduino-tips-tricks-and-techniques/arduino-uno-faq#new-usb-chip" class="anchor-link"><span class="fa fa-link" style="box-sizing: border-box; display: inline-block; font-style: normal; font-variant: normal; font-weight: normal; font-stretch: normal; line-height: 1; font-family: FontAwesome; font-size: inherit; text-rendering: auto"></span></a><span class="anchor-link-target" style="box-sizing: border-box"></span>New USB Chip</h2><span style="box-sizing: border-box">So! All of the older Arduinos (NG, Diecimila and Duemilanove) have used an FTDI chip (the FT232RL) to convert the TTL serial from the Arduino chip (Atmel ATmega). This allows for printable debugging, connecting to software like PureData/Max, Processing, Python, etc. etc. It also allows updating the firmware via the serial bootloader.<br /></span><br /><span style="box-sizing: border-box">The good news about the FT232RL has royalty-free drivers and pretty much just works. The bad news is that it can -only- act as a USB/Serial port. It can&#39;t act like a keyboard, mouse, disk drive, MIDI device, etc.</span><br /></div><div class="row-fluid build-image" style="box-sizing: border-box; position: relative; padding-bottom: 20px"><a style="box-sizing: border-box; background: transparent none repeat scroll 0% 0%; color: #00a7e9; text-decoration: none; position: relative; display: block" href="https://learn.adafruit.com/assets/3237"><img style="box-sizing: border-box; border: 0px none; vertical-align: middle; display: block; max-width: 100%; height: auto; margin: 0px auto; text-align: center" class="3237-asset img-responsive" src="https://cdn-learn.adafruit.com/assets/assets/000/003/237/medium800/learn_arduino_atmega8u2.jpg?1396794424" alt="learn_arduino_atmega8u2.jpg" /></a></div><div class="row-fluid build-text" style="box-sizing: border-box; padding-bottom: 20px"><span style="box-sizing: border-box">The Uno has changed that by exchanging the FT232RL chip with an atmega8u2 chip. There are a few things that are possible with this new chip but before we discuss that lets make it clear that by default, this chip acts identically to the FTDI chip that it replaces. It&#39;s just a USB-serial port!<br /><br /></span><span style="box-sizing: border-box">One improvement in updating the chip is that, previously, Mac users needed to install FTDI drivers. The 8u2 imitates a &#39;generic&#39; CDC serial device. So now, Mac users do not have to install a driver. Windows users still need to install the .INF file but luckily there are no drivers. This means there will be fewer problems with new versions of windows. There is no way to have a serial USB device that doesn&#39;t require an INF file in windows, sadly :(<br /></span><br />The big thing that is nice about the 8u2 is that<span>&nbsp;</span><strong style="box-sizing: border-box; font-weight: bold">advanced</strong><span style="box-sizing: border-box"><span>&nbsp;</span>users can turn it into a different kind of USB device. For example it can act like a keyboard or mouse. Or a disk driver. Or a MIDI interface, etc. Right now there are no examples of how to do this, but we hope to post some shortly.<br /></span><br />And, finally, going with the 8u2 reduced the price of the board which made up for some of the other extras.<br /></div><div class="build-faq" style="box-sizing: border-box; padding-bottom: 20px"><h2 style="box-sizing: border-box; font-family: &quot;Gotham SSm A&quot;,&quot;Gotham SSm B&quot;,Montserrat,&quot;Lucida Grande&quot;,&quot;Lucida Sans Unicode&quot;,&quot;Lucida Sans&quot;,Geneva,Verdana,sans-serif; font-weight: bold; line-height: 16px; color: inherit; margin: 10px 0px 0px; font-size: 16px; padding: 0px 0px 5px" class="question"><a style="box-sizing: border-box; background: transparent none repeat scroll 0% 0%; color: #999999; text-decoration: none; position: absolute; display: inline-block; margin-top: 3px; left: -17px; font-size: 14px" href="https://learn.adafruit.com/arduino-tips-tricks-and-techniques/arduino-uno-faq#faq-9" class="anchor-link"><span class="fa fa-link" style="box-sizing: border-box; display: inline-block; font-style: normal; font-variant: normal; font-weight: normal; font-stretch: normal; line-height: 1; font-family: FontAwesome; font-size: inherit; text-rendering: auto"></span></a><span class="anchor-link-target" style="box-sizing: border-box"></span>Why not just go with a atmega32u4?</h2><div class="answer" style="box-sizing: border-box; padding-left: 20px; margin: 0px">The Arduino team has indicated they thought about this but preferred that hackability of a DIP chip.<span>&nbsp;</span><br /><br />Right now there are a few Arduino&#39;s with a 32u4 chip such as the Leonardo, Micro and Esplora<br /></div></div><div class="build-faq" style="box-sizing: border-box; padding-bottom: 20px"><h2 style="box-sizing: border-box; font-family: &quot;Gotham SSm A&quot;,&quot;Gotham SSm B&quot;,Montserrat,&quot;Lucida Grande&quot;,&quot;Lucida Sans Unicode&quot;,&quot;Lucida Sans&quot;,Geneva,Verdana,sans-serif; font-weight: bold; line-height: 16px; color: inherit; margin: 10px 0px 0px; font-size: 16px; padding: 0px 0px 5px" class="question"><a style="box-sizing: border-box; background: transparent none repeat scroll 0% 0%; color: #999999; text-decoration: none; position: absolute; display: inline-block; margin-top: 3px; left: -17px; font-size: 14px" href="https://learn.adafruit.com/arduino-tips-tricks-and-techniques/arduino-uno-faq#faq-10" class="anchor-link"><span class="fa fa-link" style="box-sizing: border-box; display: inline-block; font-style: normal; font-variant: normal; font-weight: normal; font-stretch: normal; line-height: 1; font-family: FontAwesome; font-size: inherit; text-rendering: auto"></span></a><span class="anchor-link-target" style="box-sizing: border-box"></span>How can I change the USB firmware?</h2><div class="answer" style="box-sizing: border-box; padding-left: 20px; margin: 0px">The 8u2 can be programmed by soldering a 6-pin ISP header (the R3 has the 6-pin header pre-soldered in) and using a standard AVR programmer. You can also use the bootloader (DFU) in the 8u2. On first generation Unos, you enable this by soldering the 10K resistor right underneath the board. (R2 and R3 versions of the Uno use the 16U2 and do not require the resistor!) Again, we don&#39;t have any examples or tutorials but hope to shortly.</div></div><div class="row-fluid build-image" style="box-sizing: border-box; position: relative; padding-bottom: 20px"><a style="box-sizing: border-box; background: transparent none repeat scroll 0% 0%; color: #00a7e9; text-decoration: none; position: relative; display: block" href="https://learn.adafruit.com/assets/3238"><img style="box-sizing: border-box; border: 0px none; vertical-align: middle; display: block; max-width: 100%; height: auto; margin: 0px auto; text-align: center" class="3238-asset img-responsive" src="https://cdn-learn.adafruit.com/assets/assets/000/003/238/medium800/learn_arduino_dfushort.jpg?1396794430" alt="learn_arduino_dfushort.jpg" /></a></div><div class="row-fluid build-image" style="box-sizing: border-box; position: relative; padding-bottom: 20px"><a style="box-sizing: border-box; background: transparent none repeat scroll 0% 0%; color: #00a7e9; text-decoration: none; position: relative; display: block" href="https://learn.adafruit.com/assets/3240"><img style="box-sizing: border-box; border: 0px none; vertical-align: middle; display: block; max-width: 100%; height: auto; margin: 0px auto; text-align: center" class="3240-asset img-responsive" src="https://cdn-learn.adafruit.com/assets/assets/000/003/240/medium800/learn_arduino_8u2isp.jpg?1396794440" alt="learn_arduino_8u2isp.jpg" /></a></div><div class="row-fluid build-text" style="box-sizing: border-box; padding-bottom: 20px"><span style="box-sizing: border-box; margin-bottom: 0px">The code for the 8u2 is based on LUFA, Dean Cameran&#39;s totally awesome USB-AVR library that has great examples and documentation.

for the processor clock?</h2><div class="answer" style="box-sizing: border-box; padding-left: 20px; margin: 0px"><span style="box-sizing: border-box">The FT232RL had an internal oscillator whereas the 8u2 does not.

First there was the serial Arduino (what&#39;s the name of it?) with RS232 which was not used outside of the Arduino team &amp; friends.<span>&nbsp;</span><br /><br />The first popularly manufactured Arduino was called the NG (New Generation, like Star Trek, yknow?) The NG used the Atmega8 chip running at 16 MHz and an FT232 chip for the USB interface. The bootloader takes up 2KB of space and runs at 19200 baud.<br /><br />The next version was the Diecimila. The Diecimila updated the chip from the Atmega8 to the Atmega168. The great thing here is double the space and memory (16K instead of 8K). It still ran at 16MHz. The Diecimila also added two extra header pins for 3.3V (from the FTDI chip) and the reset pin which can be handy when a shield is covering up the Reset button. The bootloader takes up 2KB of space and runs at 19200 baud. Auto-resetting was also added which makes life awesomer for everyone.<span>&nbsp;</span><br /><br />In 2009, the Duemilanove was released. This one also upgraded the chip again, to the Atmega328. Yet another doubling of space and memory! Another upgrade is now the power is automagically switched between USB and DC-jack which removed the previous jumper. This makes it easier and faster to move from programming to standalone and got rid of some confusion. The bootloader takes up 2KB of space and runs at 57600 baud. &nbsp;<br /><br />In 2010, we have the Uno! The Uno still uses the 328P chip and the power switcher. It has a smaller bootloader called OptiBoot (more space for users&#39; projects) that runs at 115K. So even though the chip is the same, you get another 1.5K of extra flash space that was previously used by the bootloader. The FTDI chip has also been replaced with a atmega8u2 which allows for different kinds of USB interfaces. Finally, there&#39;s an extra 3.3V regulator (LP2985) for a better 3.3V supply. whew!</div><div class="row-fluid build-text" style="box-sizing: border-box; padding-bottom: 20px"><h2 style="box-sizing: border-box; font-family: &quot;Gotham SSm A&quot;,&quot;Gotham SSm B&quot;,Montserrat,&quot;Lucida Grande&quot;,&quot;Lucida Sans Unicode&quot;,&quot;Lucida Sans&quot;,Geneva,Verdana,sans-serif; font-weight: 400; line-height: 1; color: inherit; margin: 10px 0px 0px; font-size: 21px; padding-bottom: 5px"><a style="box-sizing: border-box; background: transparent none repeat scroll 0% 0%; color: #999999; text-decoration: none; position: absolute; display: inline-block; margin-top: 3px; left: -17px; font-size: 14px" href="https://learn.adafruit.com/arduino-tips-tricks-and-techniques/arduino-uno-faq#new-usb-chip" class="anchor-link"><span class="fa fa-link" style="box-sizing: border-box; display: inline-block; font-style: normal; font-variant: normal; font-weight: normal; font-stretch: normal; line-height: 1; font-family: FontAwesome; font-size: inherit; text-rendering: auto"></span></a><span class="anchor-link-target" style="box-sizing: border-box"></span>New USB Chip</h2><span style="box-sizing: border-box">So! All of the older Arduinos (NG, Diecimila and Duemilanove) have used an FTDI chip (the FT232RL) to convert the TTL serial from the Arduino chip (Atmel ATmega). This allows for printable debugging, connecting to software like PureData/Max, Processing, Python, etc. etc. It also allows updating the firmware via the serial bootloader.<br /></span><br /><span style="box-sizing: border-box">The good news about the FT232RL has royalty-free drivers and pretty much just works. The bad news is that it can -only- act as a USB/Serial port. It can&#39;t act like a keyboard, mouse, disk drive, MIDI device, etc.</span><br /></div><div class="row-fluid build-image" style="box-sizing: border-box; position: relative; padding-bottom: 20px"><a style="box-sizing: border-box; background: transparent none repeat scroll 0% 0%; color: #00a7e9; text-decoration: none; position: relative; display: block" href="https://learn.adafruit.com/assets/3237"><img style="box-sizing: border-box; border: 0px none; vertical-align: middle; display: block; max-width: 100%; height: auto; margin: 0px auto; text-align: center" class="3237-asset img-responsive" src="https://cdn-learn.adafruit.com/assets/assets/000/003/237/medium800/learn_arduino_atmega8u2.jpg?1396794424" alt="learn_arduino_atmega8u2.jpg" /></a></div><div class="row-fluid build-text" style="box-sizing: border-box; padding-bottom: 20px"><span style="box-sizing: border-box">The Uno has changed that by exchanging the FT232RL chip with an atmega8u2 chip. There are a few things that are possible with this new chip but before we discuss that lets make it clear that by default, this chip acts identically to the FTDI chip that it replaces. It&#39;s just a USB-serial port!<br /><br /></span><span style="box-sizing: border-box">One improvement in updating the chip is that, previously, Mac users needed to install FTDI drivers. The 8u2 imitates a &#39;generic&#39; CDC serial device. So now, Mac users do not have to install a driver. Windows users still need to install the .INF file but luckily there are no drivers. This means there will be fewer problems with new versions of windows. There is no way to have a serial USB device that doesn&#39;t require an INF file in windows, sadly :(<br /></span><br />The big thing that is nice about the 8u2 is that<span>&nbsp;</span><strong style="box-sizing: border-box; font-weight: bold">advanced</strong><span style="box-sizing: border-box"><span>&nbsp;</span>users can turn it into a different kind of USB device. For example it can act like a keyboard or mouse. Or a disk driver. Or a MIDI interface, etc. Right now there are no examples of how to do this, but we hope to post some shortly.<br /></span><br />And, finally, going with the 8u2 reduced the price of the board which made up for some of the other extras.<br /></div><div class="build-faq" style="box-sizing: border-box; padding-bottom: 20px"><h2 style="box-sizing: border-box; font-family: &quot;Gotham SSm A&quot;,&quot;Gotham SSm B&quot;,Montserrat,&quot;Lucida Grande&quot;,&quot;Lucida Sans Unicode&quot;,&quot;Lucida Sans&quot;,Geneva,Verdana,sans-serif; font-weight: bold; line-height: 16px; color: inherit; margin: 10px 0px 0px; font-size: 16px; padding: 0px 0px 5px" class="question"><a style="box-sizing: border-box; background: transparent none repeat scroll 0% 0%; color: #999999; text-decoration: none; position: absolute; display: inline-block; margin-top: 3px; left: -17px; font-size: 14px" href="https://learn.adafruit.com/arduino-tips-tricks-and-techniques/arduino-uno-faq#faq-9" class="anchor-link"><span class="fa fa-link" style="box-sizing: border-box; display: inline-block; font-style: normal; font-variant: normal; font-weight: normal; font-stretch: normal; line-height: 1; font-family: FontAwesome; font-size: inherit; text-rendering: auto"></span></a><span class="anchor-link-target" style="box-sizing: border-box"></span>Why not just go with a atmega32u4?</h2><div class="answer" style="box-sizing: border-box; padding-left: 20px; margin: 0px">The Arduino team has indicated they thought about this but preferred that hackability of a DIP chip.<span>&nbsp;</span><br /><br />Right now there are a few Arduino&#39;s with a 32u4 chip such as the Leonardo, Micro and Esplora<br /></div></div><div class="build-faq" style="box-sizing: border-box; padding-bottom: 20px"><h2 style="box-sizing: border-box; font-family: &quot;Gotham SSm A&quot;,&quot;Gotham SSm B&quot;,Montserrat,&quot;Lucida Grande&quot;,&quot;Lucida Sans Unicode&quot;,&quot;Lucida Sans&quot;,Geneva,Verdana,sans-serif; font-weight: bold; line-height: 16px; color: inherit; margin: 10px 0px 0px; font-size: 16px; padding: 0px 0px 5px" class="question"><a style="box-sizing: border-box; background: transparent none repeat scroll 0% 0%; color: #999999; text-decoration: none; position: absolute; display: inline-block; margin-top: 3px; left: -17px; font-size: 14px" href="https://learn.adafruit.com/arduino-tips-tricks-and-techniques/arduino-uno-faq#faq-10" class="anchor-link"><span class="fa fa-link" style="box-sizing: border-box; display: inline-block; font-style: normal; font-variant: normal; font-weight: normal; font-stretch: normal; line-height: 1; font-family: FontAwesome; font-size: inherit; text-rendering: auto"></span></a><span class="anchor-link-target" style="box-sizing: border-box"></span>How can I change the USB firmware?</h2><div class="answer" style="box-sizing: border-box; padding-left: 20px; margin: 0px">The 8u2 can be programmed by soldering a 6-pin ISP header (the R3 has the 6-pin header pre-soldered in) and using a standard AVR programmer. You can also use the bootloader (DFU) in the 8u2. On first generation Unos, you enable this by soldering the 10K resistor right underneath the board. (R2 and R3 versions of the Uno use the 16U2 and do not require the resistor!) Again, we don&#39;t have any examples or tutorials but hope to shortly.</div></div><div class="row-fluid build-image" style="box-sizing: border-box; position: relative; padding-bottom: 20px"><a style="box-sizing: border-box; background: transparent none repeat scroll 0% 0%; color: #00a7e9; text-decoration: none; position: relative; display: block" href="https://learn.adafruit.com/assets/3238"><img style="box-sizing: border-box; border: 0px none; vertical-align: middle; display: block; max-width: 100%; height: auto; margin: 0px auto; text-align: center" class="3238-asset img-responsive" src="https://cdn-learn.adafruit.com/assets/assets/000/003/238/medium800/learn_arduino_dfushort.jpg?1396794430" alt="learn_arduino_dfushort.jpg" /></a></div><div class="row-fluid build-image" style="box-sizing: border-box; position: relative; padding-bottom: 20px"><a style="box-sizing: border-box; background: transparent none repeat scroll 0% 0%; color: #00a7e9; text-decoration: none; position: relative; display: block" href="https://learn.adafruit.com/assets/3240"><img style="box-sizing: border-box; border: 0px none; vertical-align: middle; display: block; max-width: 100%; height: auto; margin: 0px auto; text-align: center" class="3240-asset img-responsive" src="https://cdn-learn.adafruit.com/assets/assets/000/003/240/medium800/learn_arduino_8u2isp.jpg?1396794440" alt="learn_arduino_8u2isp.jpg" /></a></div><div class="row-fluid build-text" style="box-sizing: border-box; padding-bottom: 20px"><span style="box-sizing: border-box; margin-bottom: 0px">The code for the 8u2 is based on LUFA, Dean Cameran&#39;s totally awesome USB-AVR library that has great examples and documentation.

First there was the serial Arduino (what&#39;s the name of it?) with RS232 which was not used outside of the Arduino team &amp; friends.<span>&nbsp;</span><br /><br />The first popularly manufactured Arduino was called the NG (New Generation, like Star Trek, yknow?) The NG used the Atmega8 chip running at 16 MHz and an FT232 chip for the USB interface. The bootloader takes up 2KB of space and runs at 19200 baud.<br /><br />The next version was the Diecimila. The Diecimila updated the chip from the Atmega8 to the Atmega168. The great thing here is double the space and memory (16K instead of 8K). It still ran at 16MHz. The Diecimila also added two extra header pins for 3.3V (from the FTDI chip) and the reset pin which can be handy when a shield is covering up the Reset button. The bootloader takes up 2KB of space and runs at 19200 baud. Auto-resetting was also added which makes life awesomer for everyone.<span>&nbsp;</span><br /><br />In 2009, the Duemilanove was released. This one also upgraded the chip again, to the Atmega328. Yet another doubling of space and memory! Another upgrade is now the power is automagically switched between USB and DC-jack which removed the previous jumper. This makes it easier and faster to move from programming to standalone and got rid of some confusion. The bootloader takes up 2KB of space and runs at 57600 baud. &nbsp;<br /><br />In 2010, we have the Uno! The Uno still uses the 328P chip and the power switcher. It has a smaller bootloader called OptiBoot (more space for users&#39; projects) that runs at 115K. So even though the chip is the same, you get another 1.5K of extra flash space that was previously used by the bootloader. The FTDI chip has also been replaced with a atmega8u2 which allows for different kinds of USB interfaces. Finally, there&#39;s an extra 3.3V regulator (LP2985) for a better 3.3V supply. whew!</div><div class="row-fluid build-text" style="box-sizing: border-box; padding-bottom: 20px"><h2 style="box-sizing: border-box; font-family: &quot;Gotham SSm A&quot;,&quot;Gotham SSm B&quot;,Montserrat,&quot;Lucida Grande&quot;,&quot;Lucida Sans Unicode&quot;,&quot;Lucida Sans&quot;,Geneva,Verdana,sans-serif; font-weight: 400; line-height: 1; color: inherit; margin: 10px 0px 0px; font-size: 21px; padding-bottom: 5px"><a style="box-sizing: border-box; background: transparent none repeat scroll 0% 0%; color: #999999; text-decoration: none; position: absolute; display: inline-block; margin-top: 3px; left: -17px; font-size: 14px" href="https://learn.adafruit.com/arduino-tips-tricks-and-techniques/arduino-uno-faq#new-usb-chip" class="anchor-link"><span class="fa fa-link" style="box-sizing: border-box; display: inline-block; font-style: normal; font-variant: normal; font-weight: normal; font-stretch: normal; line-height: 1; font-family: FontAwesome; font-size: inherit; text-rendering: auto"></span></a><span class="anchor-link-target" style="box-sizing: border-box"></span>New USB Chip</h2><span style="box-sizing: border-box">So! All of the older Arduinos (NG, Diecimila and Duemilanove) have used an FTDI chip (the FT232RL) to convert the TTL serial from the Arduino chip (Atmel ATmega). This allows for printable debugging, connecting to software like PureData/Max, Processing, Python, etc. etc. It also allows updating the firmware via the serial bootloader.<br /></span><br /><span style="box-sizing: border-box">The good news about the FT232RL has royalty-free drivers and pretty much just works. The bad news is that it can -only- act as a USB/Serial port. It can&#39;t act like a keyboard, mouse, disk drive, MIDI device, etc.</span><br /></div><div class="row-fluid build-image" style="box-sizing: border-box; position: relative; padding-bottom: 20px"><a style="box-sizing: border-box; background: transparent none repeat scroll 0% 0%; color: #00a7e9; text-decoration: none; position: relative; display: block" href="https://learn.adafruit.com/assets/3237"><img style="box-sizing: border-box; border: 0px none; vertical-align: middle; display: block; max-width: 100%; height: auto; margin: 0px auto; text-align: center" class="3237-asset img-responsive" src="https://cdn-learn.adafruit.com/assets/assets/000/003/237/medium800/learn_arduino_atmega8u2.jpg?1396794424" alt="learn_arduino_atmega8u2.jpg" /></a></div><div class="row-fluid build-text" style="box-sizing: border-box; padding-bottom: 20px"><span style="box-sizing: border-box">The Uno has changed that by exchanging the FT232RL chip with an atmega8u2 chip. There are a few things that are possible with this new chip but before we discuss that lets make it clear that by default, this chip acts identically to the FTDI chip that it replaces. It&#39;s just a USB-serial port!<br /><br /></span><span style="box-sizing: border-box">One improvement in updating the chip is that, previously, Mac users needed to install FTDI drivers. The 8u2 imitates a &#39;generic&#39; CDC serial device. So now, Mac users do not have to install a driver. Windows users still need to install the .INF file but luckily there are no drivers. This means there will be fewer problems with new versions of windows. There is no way to have a serial USB device that doesn&#39;t require an INF file in windows, sadly :(<br /></span><br />The big thing that is nice about the 8u2 is that<span>&nbsp;</span><strong style="box-sizing: border-box; font-weight: bold">advanced</strong><span style="box-sizing: border-box"><span>&nbsp;</span>users can turn it into a different kind of USB device. For example it can act like a keyboard or mouse. Or a disk driver. Or a MIDI interface, etc. Right now there are no examples of how to do this, but we hope to post some shortly.<br /></span><br />And, finally, going with the 8u2 reduced the price of the board which made up for some of the other extras.<br /></div><div class="build-faq" style="box-sizing: border-box; padding-bottom: 20px"><h2 style="box-sizing: border-box; font-family: &quot;Gotham SSm A&quot;,&quot;Gotham SSm B&quot;,Montserrat,&quot;Lucida Grande&quot;,&quot;Lucida Sans Unicode&quot;,&quot;Lucida Sans&quot;,Geneva,Verdana,sans-serif; font-weight: bold; line-height: 16px; color: inherit; margin: 10px 0px 0px; font-size: 16px; padding: 0px 0px 5px" class="question"><a style="box-sizing: border-box; background: transparent none repeat scroll 0% 0%; color: #999999; text-decoration: none; position: absolute; display: inline-block; margin-top: 3px; left: -17px; font-size: 14px" href="https://learn.adafruit.com/arduino-tips-tricks-and-techniques/arduino-uno-faq#faq-9" class="anchor-link"><span class="fa fa-link" style="box-sizing: border-box; display: inline-block; font-style: normal; font-variant: normal; font-weight: normal; font-stretch: normal; line-height: 1; font-family: FontAwesome; font-size: inherit; text-rendering: auto"></span></a><span class="anchor-link-target" style="box-sizing: border-box"></span>Why not just go with a atmega32u4?</h2><div class="answer" style="box-sizing: border-box; padding-left: 20px; margin: 0px">The Arduino team has indicated they thought about this but preferred that hackability of a DIP chip.<span>&nbsp;</span><br /><br />Right now there are a few Arduino&#39;s with a 32u4 chip such as the Leonardo, Micro and Esplora<br /></div></div><div class="build-faq" style="box-sizing: border-box; padding-bottom: 20px"><h2 style="box-sizing: border-box; font-family: &quot;Gotham SSm A&quot;,&quot;Gotham SSm B&quot;,Montserrat,&quot;Lucida Grande&quot;,&quot;Lucida Sans Unicode&quot;,&quot;Lucida Sans&quot;,Geneva,Verdana,sans-serif; font-weight: bold; line-height: 16px; color: inherit; margin: 10px 0px 0px; font-size: 16px; padding: 0px 0px 5px" class="question"><a style="box-sizing: border-box; background: transparent none repeat scroll 0% 0%; color: #999999; text-decoration: none; position: absolute; display: inline-block; margin-top: 3px; left: -17px; font-size: 14px" href="https://learn.adafruit.com/arduino-tips-tricks-and-techniques/arduino-uno-faq#faq-10" class="anchor-link"><span class="fa fa-link" style="box-sizing: border-box; display: inline-block; font-style: normal; font-variant: normal; font-weight: normal; font-stretch: normal; line-height: 1; font-family: FontAwesome; font-size: inherit; text-rendering: auto"></span></a><span class="anchor-link-target" style="box-sizing: border-box"></span>How can I change the USB firmware?</h2><div class="answer" style="box-sizing: border-box; padding-left: 20px; margin: 0px">The 8u2 can be programmed by soldering a 6-pin ISP header (the R3 has the 6-pin header pre-soldered in) and using a standard AVR programmer. You can also use the bootloader (DFU) in the 8u2. On first generation Unos, you enable this by soldering the 10K resistor right underneath the board. (R2 and R3 versions of the Uno use the 16U2 and do not require the resistor!) Again, we don&#39;t have any examples or tutorials but hope to shortly.</div></div><div class="row-fluid build-image" style="box-sizing: border-box; position: relative; padding-bottom: 20px"><a style="box-sizing: border-box; background: transparent none repeat scroll 0% 0%; color: #00a7e9; text-decoration: none; position: relative; display: block" href="https://learn.adafruit.com/assets/3238"><img style="box-sizing: border-box; border: 0px none; vertical-align: middle; display: block; max-width: 100%; height: auto; margin: 0px auto; text-align: center" class="3238-asset img-responsive" src="https://cdn-learn.adafruit.com/assets/assets/000/003/238/medium800/learn_arduino_dfushort.jpg?1396794430" alt="learn_arduino_dfushort.jpg" /></a></div><div class="row-fluid build-image" style="box-sizing: border-box; position: relative; padding-bottom: 20px"><a style="box-sizing: border-box; background: transparent none repeat scroll 0% 0%; color: #00a7e9; text-decoration: none; position: relative; display: block" href="https://learn.adafruit.com/assets/3240"><img style="box-sizing: border-box; border: 0px none; vertical-align: middle; display: block; max-width: 100%; height: auto; margin: 0px auto; text-align: center" class="3240-asset img-responsive" src="https://cdn-learn.adafruit.com/assets/assets/000/003/240/medium800/learn_arduino_8u2isp.jpg?1396794440" alt="learn_arduino_8u2isp.jpg" /></a></div><div class="row-fluid build-text" style="box-sizing: border-box; padding-bottom: 20px"><span style="box-sizing: border-box; margin-bottom: 0px">The code for the 8u2 is based on LUFA, Dean Cameran&#39;s totally awesome USB-AVR library that has great examples and documentation.

First there was the serial Arduino (what&#39;s the name of it?) with RS232 which was not used outside of the Arduino team &amp; friends.<span>&nbsp;</span><br /><br />The first popularly manufactured Arduino was called the NG (New Generation, like Star Trek, yknow?) The NG used the Atmega8 chip running at 16 MHz and an FT232 chip for the USB interface. The bootloader takes up 2KB of space and runs at 19200 baud.<br /><br />The next version was the Diecimila. The Diecimila updated the chip from the Atmega8 to the Atmega168. The great thing here is double the space and memory (16K instead of 8K). It still ran at 16MHz. The Diecimila also added two extra header pins for 3.3V (from the FTDI chip) and the reset pin which can be handy when a shield is covering up the Reset button. The bootloader takes up 2KB of space and runs at 19200 baud. Auto-resetting was also added which makes life awesomer for everyone.<span>&nbsp;</span><br /><br />In 2009, the Duemilanove was released. This one also upgraded the chip again, to the Atmega328. Yet another doubling of space and memory! Another upgrade is now the power is automagically switched between USB and DC-jack which removed the previous jumper. This makes it easier and faster to move from programming to standalone and got rid of some confusion. The bootloader takes up 2KB of space and runs at 57600 baud. &nbsp;<br /><br />In 2010, we have the Uno! The Uno still uses the 328P chip and the power switcher. It has a smaller bootloader called OptiBoot (more space for users&#39; projects) that runs at 115K. So even though the chip is the same, you get another 1.5K of extra flash space that was previously used by the bootloader. The FTDI chip has also been replaced with a atmega8u2 which allows for different kinds of USB interfaces. Finally, there&#39;s an extra 3.3V regulator (LP2985) for a better 3.3V supply. whew!</div><div class="row-fluid build-text" style="box-sizing: border-box; padding-bottom: 20px"><h2 style="box-sizing: border-box; font-family: &quot;Gotham SSm A&quot;,&quot;Gotham SSm B&quot;,Montserrat,&quot;Lucida Grande&quot;,&quot;Lucida Sans Unicode&quot;,&quot;Lucida Sans&quot;,Geneva,Verdana,sans-serif; font-weight: 400; line-height: 1; color: inherit; margin: 10px 0px 0px; font-size: 21px; padding-bottom: 5px"><a style="box-sizing: border-box; background: transparent none repeat scroll 0% 0%; color: #999999; text-decoration: none; position: absolute; display: inline-block; margin-top: 3px; left: -17px; font-size: 14px" href="https://learn.adafruit.com/arduino-tips-tricks-and-techniques/arduino-uno-faq#new-usb-chip" class="anchor-link"><span class="fa fa-link" style="box-sizing: border-box; display: inline-block; font-style: normal; font-variant: normal; font-weight: normal; font-stretch: normal; line-height: 1; font-family: FontAwesome; font-size: inherit; text-rendering: auto"></span></a><span class="anchor-link-target" style="box-sizing: border-box"></span>New USB Chip</h2><span style="box-sizing: border-box">So! All of the older Arduinos (NG, Diecimila and Duemilanove) have used an FTDI chip (the FT232RL) to convert the TTL serial from the Arduino chip (Atmel ATmega). This allows for printable debugging, connecting to software like PureData/Max, Processing, Python, etc. etc. It also allows updating the firmware via the serial bootloader.<br /></span><br /><span style="box-sizing: border-box">The good news about the FT232RL has royalty-free drivers and pretty much just works. The bad news is that it can -only- act as a USB/Serial port. It can&#39;t act like a keyboard, mouse, disk drive, MIDI device, etc.</span><br /></div><div class="row-fluid build-image" style="box-sizing: border-box; position: relative; padding-bottom: 20px"><a style="box-sizing: border-box; background: transparent none repeat scroll 0% 0%; color: #00a7e9; text-decoration: none; position: relative; display: block" href="https://learn.adafruit.com/assets/3237"><img style="box-sizing: border-box; border: 0px none; vertical-align: middle; display: block; max-width: 100%; height: auto; margin: 0px auto; text-align: center" class="3237-asset img-responsive" src="https://cdn-learn.adafruit.com/assets/assets/000/003/237/medium800/learn_arduino_atmega8u2.jpg?1396794424" alt="learn_arduino_atmega8u2.jpg" /></a></div><div class="row-fluid build-text" style="box-sizing: border-box; padding-bottom: 20px"><span style="box-sizing: border-box">The Uno has changed that by exchanging the FT232RL chip with an atmega8u2 chip. There are a few things that are possible with this new chip but before we discuss that lets make it clear that by default, this chip acts identically to the FTDI chip that it replaces. It&#39;s just a USB-serial port!<br /><br /></span><span style="box-sizing: border-box">One improvement in updating the chip is that, previously, Mac users needed to install FTDI drivers. The 8u2 imitates a &#39;generic&#39; CDC serial device. So now, Mac users do not have to install a driver. Windows users still need to install the .INF file but luckily there are no drivers. This means there will be fewer problems with new versions of windows.

You can also use the bootloader (DFU) in the 8u2. On first generation Unos, you enable this by soldering the 10K resistor right underneath the board. (R2 and R3 versions of the Uno use the 16U2 and do not require the resistor!) Again, we don&#39;t have any examples or tutorials but hope to shortly.</div></div><div class="row-fluid build-image" style="box-sizing: border-box; position: relative; padding-bottom: 20px"><a style="box-sizing: border-box; background: transparent none repeat scroll 0% 0%; color: #00a7e9; text-decoration: none; position: relative; display: block" href="https://learn.adafruit.com/assets/3238"><img style="box-sizing: border-box; border: 0px none; vertical-align: middle; display: block; max-width: 100%; height: auto; margin: 0px auto; text-align: center" class="3238-asset img-responsive" src="https://cdn-learn.adafruit.com/assets/assets/000/003/238/medium800/learn_arduino_dfushort.jpg?1396794430" alt="learn_arduino_dfushort.jpg" /></a></div><div class="row-fluid build-image" style="box-sizing: border-box; position: relative; padding-bottom: 20px"><a style="box-sizing: border-box; background: transparent none repeat scroll 0% 0%; color: #00a7e9; text-decoration: none; position: relative; display: block" href="https://learn.adafruit.com/assets/3240"><img style="box-sizing: border-box; border: 0px none; vertical-align: middle; display: block; max-width: 100%; height: auto; margin: 0px auto; text-align: center" class="3240-asset img-responsive" src="https://cdn-learn.adafruit.com/assets/assets/000/003/240/medium800/learn_arduino_8u2isp.jpg?1396794440" alt="learn_arduino_8u2isp.jpg" /></a></div><div class="row-fluid build-text" style="box-sizing: border-box; padding-bottom: 20px"><span style="box-sizing: border-box; margin-bottom: 0px">The code for the 8u2 is based on LUFA, Dean Cameran&#39;s totally awesome USB-AVR library that has great examples and documentation.
