I am using a potentiometer at the moment to select 4 states of a menu, but I'd like a more postive feel as the user twists the knob. The trouble is I only have 1 digital pin left available but all of the anlogue pins.
I was thinking of using a rotary encoder but the code looks very complicated vs what I'm using for the potentiometer. I could just do with some general advice, how to make the selection more postive using whatever method with the remaining pins I have. TIA!
