# Welcome to WLED! ✨
A fast and feature-rich firmware for ESP32 microcontrollers to control addressable LEDs — from simple strips to large 2D matrices and HUB75 panels.
Originally created by [Aircoookie](https://github.com/Aircoookie), now maintained by a community of contributors.
## ⚙️ Features
### Effects & Visuals
- [**200+ built-in effects**](https://kno.wled.ge/features/effects/) including classic animations, audio-reactive, and 2D/matrix effects
- [50+ color palettes](https://kno.wled.ge/features/palettes/) plus a built-in **custom palette editor** (PixelForge)
- [**2D LED matrix support**](https://kno.wled.ge/advanced/mapping/) with dedicated 2D effects and flexible panel mapping
- [**HUB75 RGB matrix panel support**](https://kno.wled.ge/advanced/HUB75/) (ESP32)
- [**AudioReactive**](https://kno.wled.ge/advanced/audio-reactive/) effects — included by default, responding to sound via microphone, line-in, or network audio source
- Effect blending for smooth transitions between animations
- Antialiased drawing functions for smooth graphics
### Segments & Control
- [**Segments**](https://kno.wled.ge/features/segments/) — apply different effects, colors and palettes to independent parts of your LED setup simultaneously
- Up to **250 presets** to save and recall colors, effects and segment configurations — supports [playlists](https://kno.wled.ge/features/presets/) for automated cycling
- Nightlight function with configurable dimming curve
- Configurable **Auto Brightness Limiter** (per output) for safe operation
### Hardware Support
- **ESP32** (all variants: original, S2, S3, C3)
- [**Up to 17 LED outputs**](https://kno.wled.ge/features/multi-strip/) on ESP32 using parallel I2S + RMT
- [Addressable LED support](https://kno.wled.ge/basics/compatible-led-strips/): WS2812B, WS2811, WS2815, SK6812, WS2805, TM1914, APA102, WS2801, LPD8806, and many more
- RGBW, [RGB+CCT](https://kno.wled.ge/features/cct/) and white-only strips
- PWM outputs for analog LEDs and dimmers
- [**Ethernet** support](https://kno.wled.ge/features/ethernet-lan/) for a wide range of boards (QuinLED, LILYGO, Olimex, and more)
- Filesystem-based config for easy backup and restore of presets and settings
- Full OTA firmware updates (HTTP + ArduinoOTA), password-protectable
### Connectivity & Integrations
- **WLED app** for [Android](https://play.google.com/store/apps/details?id=ca.cgagnier.wlednativeandroid) and [iOS](https://apps.apple.com/gb/app/wled-native/id6446207239)
- [JSON](https://kno.wled.ge/interfaces/json-api/) and [HTTP request](https://kno.wled.ge/interfaces/http-api/) APIs
- **Multi-WiFi** — connect to up to 3 networks with automatic AP fallback
- **ESP-NOW** wireless sync between devices (no WiFi router required)
- [**MQTT**](https://kno.wled.ge/interfaces/mqtt/) with Home Assistant discovery
- [**E1.31, Art-Net**](https://kno.wled.ge/interfaces/e1.31-dmx/), [DDP](https://kno.wled.ge/interfaces/ddp/) and [TPM2.net](https://kno.wled.ge/interfaces/udp-realtime/) for DMX/professional lighting control
- [UDP realtime sync](https://kno.wled.ge/interfaces/udp-notifier/) across multiple WLED devices
- Alexa voice control (on/off, brightness, color)
- [Philips Hue sync](https://kno.wled.ge/interfaces/philips-hue/)
- [diyHue](https://github.com/diyhue/diyHue) and [Hyperion](https://github.com/hyperion-project/hyperion.ng) integration
- [Adalight / TPM2](https://kno.wled.ge/interfaces/serial/) (PC ambilight via serial)
- [Infrared remote control](https://kno.wled.ge/interfaces/infrared/) (24-key RGB, receiver required)
- Timers and schedules (NTP time sync, full timezone and DST support)
### Developer-Friendly
- **Usermod system** — extend WLED with community or custom modules without modifying core code
- Large and active [usermod library](https://kno.wled.ge/advanced/community-usermods/) including AudioReactive, temperature sensors, rotary encoders, displays, and much more
- Well-documented [JSON API](https://kno.wled.ge/interfaces/json-api/)
- Licensed under the **EUPL v1.2**
