(D6 of Arduino connected to Din of WS2812B) It is highly recommended to connect a 100nF capacitor across the ‚5v and Gnd‛ connection, and a 100-470 Ohm resistor in series with the ‚Din‛ line of the ...

The build is open-source, and designed to work with strings of 60, 120, or 180 WS2812B LEDs. An Arduino Nano is charged with running the show, capturing audio via its analog-to-digital converter.
