Re: Robo Rio Digital Inputs Question.
There is a pullup resistor and you can select the power line to be 5v or 3.3v. I'd have to experimentally try the thresholds but 0.7v and 1.4v are typicall thresholds for digital logic.
What kind of sensor are you trying to use and why not use the analog inputs?
