## What it is
An Arduino library for controlling single-wire LED pixels and strips such as NeoPixels, WS2812, and Adafruit FLORA pixels. It supports a wide range of microcontrollers including AVR, SAMD, ESP8266/ESP32, and nRF52.

## Use cases
- control ws2812 led strip from arduino
- animate neopixel rgb pixels
- drive led matrix on esp32
- make colorful led animations on microcontroller
- light up adafruit flora smart pixels
- program led strip effects on teensy

## When to choose
- you use Arduino IDE with supported boards like AVR, SAMD, ESP32, or nRF52
- you want a simple, well-documented API for single-wire LED strips
- you use Adafruit NeoPixel hardware

## When to avoid
- your board or port (e.g. AVR Port A) is unsupported
- you need addressable LEDs over SPI or other protocols
- you work outside the Arduino ecosystem

## Facets
- artifact type: library
- maturity: stable
- function: embedded, graphics
- domain: embedded-systems, hardware, developer-tools
- platform: embedded, cpp, iot
- tags: arduino, neopixel, ws2812, led-strips, single-wire-protocol
