This tabletop device simplifies the core logic of one channel, one light, from the Colour Organ into a self-contained object. Built around an Arduino Uno and an MSGEQ7 seven-band filter, it uses just a handful of parts—a pre-amp, a WS2812 ring in a opaque bulb, and an SG90 micro-servo—to isolate a narrow mid-range frequency band and transform its amplitude into both light and motion. A straightforward envelope-follow algorithm delivers instant attack and smooth decay without any heavy digital signal processing, and while the motorized sway is still being tuned, the basic sound-to-light translation is good.
