Holiday lighting has long relied on repeated patterns and static effects, but this music-reactive LED Christmas tree brings a new dimension to seasonal decor by turning sound into visual effects. The project is a simple wooden frame with off-the-shelf LEDs and an audio sensor to create a festive display that animates in real time with sound. Built around an ESP32 microcontroller running the open-source WLED software, the assembly combines woodworking, basic electronics, and wireless configuration into a project that is both instructive and visually striking.

Adrelien inESP32 -The ESP32 is a powerful microcontroller with built-in Wi-Fi, making it an excellent choice for IoT projects. In this guide, we will walk you through how to collect soil moisture data from a 2-prong soil sensor, send it to the cloud using Telemetry Harbor, and visualize it using a Grafana dashboard Arduino IDE (1.8.13 or newer) Required libraries: Telemetry Harbor SDK WiFi Library (built into ESP32 core) HTTPClient Library (built into ESP32 core) Telemetry Harbor account (free tier available)
