“This instrument produces tones or sounds based on the light that falls on the surface of the photoresistor.
The Theremin is an electronic musical instrument controlled without physical contact by the thereminist (performer). It is named after its inventor, Leon Theremin, who patented the device in 1928.
This time I will show you how to make such an instrument that produces tones or sounds based on the light that falls on the surface of the Photoresistor. By moving your hand over the photoresistor, the intensity of light falling on it, changes, and that change the pitch. The device is very simple to build and can be successfully made by a beginner. It also does not require a separate power supply and is powered via the USB port of Arduino.
Contains only a few components:
- Arduino nano microcontroller
- Photoresistor
- Speaker
- Two trimmer potentiometers
- and two resistors”
