It then controls a WS2812B LED strip to display the time. The strip itself is hidden in a 3D-printed housing behind an opaque wooden ring, with the light from the LEDs diffusing out nicely on to ...

[Jeremy] does a great job outlining how it all works, covering everything from the data format used by WS2812B LEDs to the way cache needs to be handled to avoid garbled data.

– LED Compatibility: Open source Arduino sketch with FastLED library will support various strips strips: WS2812, WS2812B, WS2811, TM1804, etc.

The LED Corners have been specifically designed to easily join Neopixel/WS2812B strips at right angles, with no mess no fuss, watch the video below to learn more.
