This is a Drum Machine made with Arduino Uno, Leds and some knobs. It doesn't require any hats or external components to emit sound and sounds are configurable.

Simple drum machine can be operated entirely with 5 knobs and 1 button. The first knob will change beats per minute and other 4 knobs will determine what to play in every beat. 4 Leds identify current beat.
