    Individually addressable RGB LEDs like the WS2812B models are popular because they’re so easy to drive and don’t require any complex wiring. Each LED in the chain passes a signal on to its neighbor and you only need to know the position of an LED in the chain to control its brightness and color. This project from Andrei Erdei shows how to use that to great effect in a minimalist lamp.

    This lamp is charming in its simplicity. It has an opaque outer ring with a slightly thicker base and a translucent inner ring to diffuse the LEDs. When all of the LEDs are a single color, it is a unique lamp. But because they’re WS2812B LEDs, you can take advantage of the available Arduino libraries to produce all kinds of interesting lighting effects.

    The frame is entirely 3D-printable. The only required components are an Arduino Nano board, a strip of 36 WS2812B LEDs (the 60 LEDs per meter density), and a power supply. The tutorial provides a sketch with lighting effects and also explains how to work with the FastLED Arduino library. That library is fantastic for easily controlling dozens or even hundreds of LEDs, so you can create whatever effects you can imagine.

    There are already countless projects that utilize individually addressable RGB LED strips in some way or another, except most of them lack a “wow” factor. This is one problem that Philipp Niedermayer’s Sphere2 Lamp does not suffer from, as it is a giant sphere comprised of 122 smaller domes (cut ping pong balls) that are each lit by their own LED. The project uses an Arduino Nano running code with the FastLED library to output signals via its GPIO pins to the LEDs. It is controlled over its serial interface by a Nano 33 BLE Sense since the latter has integrated BLE functionality. 

    Niedermayer also wrote a dedicated app for starting and stopping animations on the Sphere2 Lamp. The Android application features an interface that lets users control not only the selected color or colors, but the brightness and the speed at which the animation plays as well. Currently, the app has a set of around both ten animations and color palettes each, although this number can certainly be increased in the future. 

    The Sphere2 Lamp is an extremely unique-looking showcase of what is capable with just a couple of Arduino boards, some LED strips, and innovative programming. You can view the project’s write-up here on Hackster.io and see its code on GitHub.
