There is absolutely no programming involved in connecting things to the OI. It is what it is, and we can't change how it works.
For a rotation input, a simple potentiometer will work. If the control needs to spin continuously, use a pot without an end stop. There is some programming you can do here, to accommodate the sudden jump from one end of the scale as the potentiometer wraps around. If your rotation rate is slow enough, you might be able to get away with using a quadrature sensor and a pair of digital inputs, but I wouldn't count on it.

The pot switch I did think of and it likely would work, I was just wondering if there was anything out there that is infinite, and just returned a +/- degrees of rotations just add the value to an int, that way I could know say if the switch had been turned 720 degrees and have a different effect then if it was turned 360 degrees.

Its purpose would be to aid the driver with controlling an attachment, if we end up going with one of our ideas we are considering.
