Controlling music playback using a cooler

What people with "crazy hands" can’t come up with. One craftsman, using a system on Arduino, assembled a setup that plays music from an old cassette player using a cooler, and the playback speed is controlled by the rotation speed of the cooler. Initially, it was thought that the cooler would just spin to the beat of the music, but then it was all improved, and that's what happened.



PS I apologize if it was, since I came across only today.
