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