Trouble with Serial1 and Digital 2 (pin 2) input on Leonardo

Nevermind, my inputs had a different ground than the Arduino. It was close, but apparently connecting the other serial thing made stuff float enough to confuse the inputs. Connecting the grounds for the devices fixed it :)

I suspect it would have helped others if you had left your original post and added a second post with your solution rather than deleting the problem description.


Ah, the age old problem of having two inputs that cannot find common ground.
