A theremin is an electronic instrument in which two high-frequency oscillators control tone while the musicians hand movements control the pitch.

In this free Arduino project, we’ll build a similar instrument, in which hand movements control the amount of light that the instrument’s sensors receive, and that light measurement is converted into a resulting pitch from a buzzer.

What You’ll Learn

When you are finished with this project, you’ll be able to:

  • Build a circuit using aphotoresistor
  • Read and translate analog input on a microcontroller
  • Map readings to tones to create music

What You’ll Need

To complete this project, you’ll need the following components
