Solar theremin with Arduino




Step 1: Why?

During the 2014 art Exhibition at Met (M. di Ragusa), I created (with the technical collaboration of Carmel Iurato), this theremin made from three photoresistors, managed by the light and powered by a solar panel. All controlled by Arduino Uno. A musical composition of light and shadows.

Step 2: How to

the LED is the BUZZER!
