say i have a pot that is putting out 3.15v at its minimum. would it be possible to run that voltage in to a digital input and have it act as a switch for anything above the 3.15v?
if so, how would you go about doing that?
i have been trying to wrap my brain around it all morning.
i've been trying funky hardware solutions, trying to add resistors to drop the 3.15v and such but it isn't working. it seems like there must be a solution with code. :-/
