How do I find grounds

<< < (2/2)

brack:
Any board I've ever seen has lines you can trace from the buttons.  If you look closely enough the ground sides of them are usually connected to each other.

ArcadEd:
BINGO to what Brack said :).

Look at the traces.  There will be one that goes to one side of every button area.  That is your common ground.  The other side of that button is the "hot" in this case.

I'm about to solder up two of those exact same pads, so if you need help let me know.

danny_galaga:
