Smart light

Smart lights come in all sorts of shapes and colors. The most common way of implementing a smart light is using LEDs. They are perfect for basic illumination, creating cozy atmospheres, enhancing art and music experiences, festive decorations, visual alerts, signage, and much more, offering endless possibilities for makers.

Addressable LEDs

The firmware on this page is an example implementation of a smart light device using WS28xx addressable LED pixels, one of the most popular products when it comes to LED lights and microcontroller modules.

With the color-light firmware and WS2812 RGB LEDs is possible to build smart lights with an arbitrary number of color-changing LEDs that can be independently addressed.

This type of LED only requires 3 wires (VCC, GND and a GPIO pin) to connect to the microcontroller.
