TUI DJ

For our instrument we synthesized a DJ turntable using cardboard and construction paper for an abstract representation.  We adapted the theory behind the Theremin, which involves no physical touch necessary to the actual interface, instead using photocells which we wired underneath the "turntable" connectedly corresponding to LED lights and then to the Arduino, one need only to wave their hands above a series of photocells embedded in the paper representation of two  records in order to produce an array of sounds paired with different colored dimming lights.   Boom.  Magic!
