Here is a project that shows how to use a mini TrackBall to control stuff with a PIC etc.
For the moment it just uses the TrackBall X and Y values to control the colour and brightness of a RGB led, to make a test of a "Mood Light".
The trackballs are very cheap from a surplus reseller and have 2 rotary quadrature encoders one for X and one for Y. Not bad in a little neat package a little over an inch!
I'm considering a future project that uses a trackball on a bench PSU to control volts and amps, and would also appreciate any other ideas for projects using a TrackBall as i bought quite a few while they're cheap.
