I'm setting up the GPIO pins to wire with buttons and just would like to confirm some info.
I have read the instructions and somehow, it seems to be that AOP does it the other way around?
Say I want to add a switch input for Pin 12, do I run the other end to a 5v supply or ground?
The instructions says that a press signal would read as HIGH...which is normally the other way around when I wire Arduino pins.
