From the project
Hardware design, BOM, gerbers and 3D files for Smart-LED-WS2812B-Ring7 designed by Soldered Electronics.
WS2812B is an extremely interesting LED that can emit light in red, green or blue – or any combination of these three colors, able to show a total of approximately 16 million different colors. On this board, diodes are arranged in a circle. They are controlled by a single pin with only a few lines of code from Arduino IDE. That’s possible thanks to the integrated controller inside the LED itself!
