The quadrature encoder with acceleration would seem easiest, but it still needs coding. My bright (I claim…) idea is to use two potentiometers connected to two analogue arduino inputs (method below), ...

The encoder we had was on a little PCB that you get when you buy one of those Chinese Arduino 37 sensor kits. (By the way, if you are looking for documentation on those kinds of boards, look here ...
