I am working on an arcade stick that is feeding data in to an arduino, which will then either send that line to GND or HIGH. Arcade sticks work by having all the buttons daisy chained on the GND side, and the positive leads connecting to their own specific pins on an IC. WHen the button is depressed…

Using digital pins as GND

Analog values, different value resistors. Yes it can easily be done... But for a different reason, Why? are you trying for AI... to beat the game?
