I plan on using a 12 position rotary switch into one of the analog in pins (I'm using 6 of these things, so that would gobble a TON of digital pins). I plan on just connecting resistors across the pins to make a ladder sort of thing. Has anyone done something like this? What value resistors did you…

Rotary switch as stepped potentiometer into analog in....?

My guess is 11 clicks, giving 12 different values.
