Mini IR Theremin

Posted July 7, 2011 by Chris

If you’re a music lover, this Pyro Electro project is for you. Today I show you how to build your own IR Theremin. This style of theremin uses an infrared proximity sensor, a headphone speaker and a PIC micro to create an off-the-shelf style of instrument. The article includes demo vids of me playing simple songs on the theremin.
