Description: Using an Arduino or a micro controller we can generate cool looking patterns with an led strip with addressable LEDs. In this case I'm using an Arduino uno (clone board) and a strip of ...

WS2812B & Arduino Earlier we controlled LED matrixes, strips and other complex LED projects bundled with countless interconnected wires with the help of multiplexers and shift registers.

Each individual tree has three WS2812b-mini addressable RGB LEDs and the tree is controlled by an external Arduino. The first order of 10 PCBs came in, which makes a 9 member tree – next up is a ...

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.
