Fast, easy LED library for Arduino
FastLED is a fast, efficient, easy-to-use Arduino library for programming addressable LED strips and pixels such as WS2810, WS2811, LPD8806, Neopixel and more. FastLED is used by thousands of developers, in countless art and hobby projects, and in numerous commercial products.
We build FastLED to help you get started faster, develop your code faster, and make your code run faster.
Great compatibility
FastLED supports popular LEDs including Neopixel, WS2801, WS2811, WS2812B, LPD8806, TM1809, and more. The library runs on a wide range of Arduino and compatible boards, including both AVR- and ARM- based microcontrollers.
Great features
In addition to fast, efficient, compatible LED driver code, FastLED also provides features that get your animations up and running fast:
- Full HSV color support as well as classic RGB
- Master brightness setting (nondestructive) controls brightness, power use, and battery life
- Fast math and memory functions up to 10X faster than standard Arduino libraries
- User community of thousands, who share tips, ideas, and help
- Multi-year history of active development and evolution
- Ruthless efficiency, an almost fanatical devotion to performance, and nice RGB uniforms.
