  • So - this tutorial makes it look like you don’t need power and ground running to the switch unless you’re using LEDs - but that can’t be right, can it?

    • You need ground on one pin and a pull-up resistor on the other (in the most common hookup, at least.) As an example: ground pin 2 and put a pull-up resistor on pin 1. Then monitor pin 1 – if it’s low, the switch is activated, otherwise it’ll be high.
