We have the idea of creating ??a big "vinyl player". The idea for the concept comes from an barrel organ (http://en.wikipedia.org/wiki/Barrel_organ '). The idea is that we have a circular track we'll lasercut with increase and decrease levels. On the track we want to put arduino. This rotates about the circular track. The arduino measures the increase and the decrease of the track and sends that value. The track consists of 4 different lines. If an increase is observed, it must play musical note ('processing'). So we want to play a full track consisting of 4 musical notes. The song plays continuously , so it is circular. For the duration of 1 song is 1 rotation.
Now our question to you: How do we measure that increase and decrease on the track? So we get a clear signal whether a note should be played or not.
which sensor can we use for it? together with any code?
