About
FastLED provides a powerful, hardware-abstracted API for driving dozens of LED chipsets (WS2812, APA102, SK6812, etc.) with smooth animations, color math, and power management. It is the de facto standard for anyone building LED projects on Arduino, ESP32, or Teensy platforms, with over a decade of active maintenance and a large community.
