🧰 Project 4B: Theremin aka The Annoyer 9000!

This Project is an Example of…

Most cars today have an alert sound, as if to say “you’re too close!”, when they are approaching another vehicle.

In this project we are going to build the most annoying thing one could imagine... THE THEREMIN!

By using a photoresistor to detect ever-so-slight changes in light when we move our hands, our microcontroller will change the pitch and volume of the speaker output to create different notes!

A person playing an actual theremin will move one hand to change the frequency of a note and the other hand to alter the amplitude (volume). Check out this video from SciShow to learn more!
