Build:Th3remin

I present you a LEGO Mindstorms EV3 Theremin.

This project is a representation of the special musical instrument created by Lev Sergueïevitch Termen (represented by the minifigure) in 1920.

This build works using two distance sensors.

The first of them (at the bottom right) controls the voluma sounds: the closer the obstacle, the lower the sound.

The second sensor (at the top left) controls the frequency sounds: the closer the obstacle, the higher the frequency.

Then, we can make a melody.

This instrument is convenient during this period because it's a contactless instrument.
