Wooden blocks trigger sounds on Arduino-programmed turntables

Mix three turntables with some Arduino boards and five sensors each. Program different sounds — bongos, bass, a snare drum, hi-hat, whatever you’d like — and then position small wooden blocks on the turntables to trigger those sounds. By playing with the block positions, you create new beats.

This is Beat Blox by Per Holmquist, a simple interface for making sophisticated and fun rhythmic loops, perfect for almost any age. Not only is the idea super accessible, but we love the graphic styling and bold colors of the turntables, speakers, and blocks.
