Individually addressable RGB LEDs just like the WS2812B fashions are in style as a result of they’re really easy to drive and don’t require any advanced wiring. Every LED within the chain passes a sign on to its neighbor and also you solely must know the place of an LED within the chain to manage its brightness and colour. This challenge from Andrei Erdei reveals how one can use that to nice impact in a minimalist lamp.

This lamp is charming in its simplicity. It has an opaque outer ring with a barely thicker base and a translucent internal ring to diffuse the LEDs. When all the LEDs are a single colour, it’s a distinctive lamp. However as a result of they’re WS2812B LEDs, you’ll be able to make the most of the out there Arduino libraries to provide all types of fascinating lighting results.

The body is totally 3D-printable. The one required parts are an Arduino Nano board, a strip of 36 WS2812B LEDs (the 60 LEDs per meter density), and an influence provide. The tutorial offers a sketch with lighting results and in addition explains how one can work with the FastLED Arduino library. That library is implausible for simply controlling dozens and even a whole lot of LEDs, so you’ll be able to create no matter results you’ll be able to think about.
