A phenomenal minimalist rainbow LED lamp

Individually addressable RGB LEDs just like the WS2812B fashions are widespread as a result of they’re really easy to drive and don’t require any complicated 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 regulate its brightness and coloration. This undertaking from Andrei Erdei reveals the right way to 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 inside ring to diffuse the LEDs. When all the LEDs are a single coloration, it’s a distinctive lamp. However as a result of they’re WS2812B LEDs, you may reap the benefits of the out there Arduino libraries to provide every kind of fascinating lighting results.

The body is completely 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 supplies a sketch with lighting results and in addition explains the right way to work with the FastLED Arduino library. That library is unbelievable for simply controlling dozens and even a whole lot of LEDs, so you may create no matter results you may think about.
