How it works

A theremin has basically two controls:

1. pitch

2. volume

In this example these two parameters are changed moving two slide potentiometers, but you can modify it to read them using for example a ping sensor! In this way your theremin will be more realistic!

The two potentiometers are wired in a voltage divider fashion, so moving them you will get (from analogRead()) values in the range 0 - 1023. These values are then mapped to between the minimum and maximum frequency and the minimum and maximum volume.

The sound sent on the I2S bus is a simple sine whose frequency and amplitude is changed according to the potentiometers reading.
