Control music playback with the cooler

That only people with "crazy hands" will not think up. One craftsman, using a system on the Arduino, assembled a setup that plays music from an old cassette player using a cooler, and the playback speed is governed by the rotation speed of the cooler. Initially it was thought that the cooler would simply spin to the beat of the music, but then it was all improved, and that's what happened.



PS I apologize if it was, as I stumbled only today.
