I'd like to use it as an analog input for a switch. From what I've read and been told it must not drop below a certain voltage. Firstly, is that statement true?
If so, what is that voltage? I'm confused as to what the data sheet is actually defining.
Secondly, how on earth would I connect one up and what would it look like in the sketch? Would it just be like any other switch? I assume if it were to input at 0 @ 0v (open) it wouldn't even reset? And if it were to switch and send input value 1 (or 255) @ 5V it would be fine?
