+## WS2812 Status LED (NeoPixel)
+
+This firmware includes support for a single WS2812 (NeoPixel) LED as a system status indicator.  
+It has been tested on the **Freenove ESP32-S3 Audio Kit**, where the LED is connected to **GPIO48**.
+
+### Requirements
+Add the [Adafruit NeoPixel library](https://github.com/adafruit/Adafruit_NeoPixel) to your `platformio.ini`:
