when you set a pin to input, you want that to be a very high resistance, right? What's the input impedance of an amplifier? PROFESSOR 2: Very high.

1:16 If you set it as an output mode, then you're driving-- what you then be looking at, really? PROFESSOR 2: Very low resistance.


1:32 PROFESSOR 2: OK, so when we're actually setting the pins, in the code, to be inputs or outputs, we're actually changing the impedance that's the pin.


1:46 Yeah, I was connecting the supply wire to the capacitor, pulling it off by hand. Pulling it off by hand is like putting a really high impedance there between those.
