Phantom Button Presses
I have a momentary button connected to an Arduino Uno, one pin to pin A0 and one pin to GND, and I'm using the internet pull-up resistors on the Arduino. I'm having issues with the Arduino detecting a button press when the button hasn't been touched. Is there any way I can fix this?

Re: Phantom Button Presses
Could you post the code you're using please, along with a clear photo of the board, button, and wiring? Also, if you don't have to use A0 try a different pin, I seem to recall issues w A0 w internal pullup.
