Arduino and Embedded Programming

My current obsession is endless rotary encoders and what use they can be put to. Often the only place you find them, in retail at least, is on expensive Midi controllers. Now cheap rotary encoders can be had on Amazon for not a lot, and Arduino boards (especially clones) don't cost a lot. So the idea occurred to me of building my own control surfaces. They simply need to report movements over a serial line – no need for a complicated protocol like Midi.
