Re: 0 or 1?
Commonly:

+5V is a digital 1
0V is a digital 0

This is the case in the FIRST robot controller.

There are other protocols and standards that use different voltage levels to represent 1's and 0's, but I'm not aware of anything in the FIRST RC that is not 5V/0V.

As was mentioned before: remember that if you connect nothing to an input, they will default to +5V (not 0V) when the controller is on.

Good luck!
