  • @jimblom I'm having trouble with this. I'm building a 1-column 3-row macropad, and I've wired everything the way your guide instructs. I'm still unsure of where to connect to ground. Does each breakout board get connected to ground? Which spot on the breakout board gets connected to ground? More information on this would be extremely helpful.

  • 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.
