Raspberry Pi Forums

I would like to connect 12 tact buttons on the gpio but there is only 8 gnd, can I connect more than one button to the same ground or is there any other workaround to this issue?

This is basic stuff that I can't just simply try out instead of asking cuz my pi didn't arrive yet so I am gathering the most information that I can to make my project easier later on.

oh and by the way, I read on google that a teensy can solve this using the USB port instead but I am on a budget..
Thanks

No worries. All grounds are the same. You can connect all your switches to the same ground, or some to one, and some to another.

Have fun!
