WLED is a fast, feature‑rich firmware for ESP32/ESP8266 that turns the microcontroller into a Wi‑Fi‑controlled LED controller. It provides a web UI, JSON/MQTT APIs and many built‑in effects for addressable LED strips and matrix panels.

Use cases

• Control WS2812B or similar addressable LED strips from a smartphone or web browser.
• Create synchronized light shows across multiple ESP devices using UDP or MQTT.
• Integrate LED lighting with Home Assistant, Alexa, or other smart‑home platforms.
• Run audio‑reactive visualizations that respond to music or microphone input.
• Drive 2D LED matrices or HUB75 panels for video wall displays.

When to choose

• You need a low‑cost, Wi‑Fi‑enabled controller for addressable LEDs.
• You want a rich set of built‑in effects and a web‑based UI without writing code.
• You plan to integrate LED control into existing smart‑home ecosystems via MQTT or HTTP APIs.
• You prefer flashing firmware directly from a browser or using simple GUI tools.

When to avoid

• You require professional DMX or high‑speed realtime protocols beyond what ESP can reliably handle.
• You need more than the ESP’s GPIO/LED count limits (e.g., thousands of LEDs with strict timing).
• You need a fully open‑source stack with no proprietary components or a non‑Wi‑Fi communication method.
• You require advanced video processing or high‑resolution graphics beyond the ESP’s capabilities.
