DIY Music Reactive "Rings of Saturn" LED Pendant Light (controlled by Arduino) || How to Make

FOLLOW ME ON INSTAGRAM: @modustrialmaker ||

This video shows how to make an LED pendant light from plywood, LED strips, and flexible LED channel. Since I designed this for my living room, the music reactive / sound reactive mode had to be incognito. With this in mind, I used warm white / cool white / amber LED strips, instead of RGB strips. In solid white mode, the rings give off various shades of white for a sophisticated modern look that hides the wild side when you switch the light to music visualizer mode.

The build is fairly simple. Each of the two rings is made of a stack of three plywood rings, where the middle ring has a lesser radius to create a groove for the LEDs. The rings are simple to cut using a circle cutting jig and router. While I programmed an Arduino Mega to do music visualization based on input from a microphone, you can very easily buy an off-the-shelf music controller for individually controllable LEDs, which is basically plug n’ play for the LED strips.
