You can also adjust light sensor settings to make it react to light instead of darkness or to increase or decrease sensitivity. And of course you can control BPM of your beat by regulating the slide dimmer.
You can use it to make your music or as a metronome.
To make it you need one 3D-printed detail - 3d model is available to download.
