The WS2812D-F8 is a high-tech, digitally programmable 8 mm RGB LED that’s individually addressable in daisy chains of up to 255 devices. In this 3D Circular Christmas Tree Project, 36 of these devices can be controlled externally or by an onboard Arduino Nano ESP32. The light effects are astonishing — you can’t miss having this illuminating Elektor​​​​​​ kit for the Holidays!
