GCDuino Theremin

Firstly if you are too young to know what a Theremin is – head on over to the Wikipedia page to find out more. In a nutshell, the Theremin is a musical instrument that can be played without physical contact by the musician.

The original Theremins used radio antennas but our version is considerably simpler using a simple LDR (light dependent resistor) to detect how close your hand is and change the tone on the speaker accordingly. We also added a battery (using an old camera battery Рthese things last forever on Arduino  projects as they have very high mAh values) and an RGB Led for extra effect.
