Project Overview

This project aims to create a sound-reactive LED matrix that visualizes the sound levels in a room. Using a sound sensor module and an RGB LED matrix (Unicorn pHAT), the device will display dynamic animations that change based on the detected sound intensity.

Features

• 🎵 Measure sound levels in real-time using a sound sensor
• 🌈 Display dynamic animations on an RGB LED matrix
• 📡 WiFi-enabled for remote monitoring and control
• 🔌 Powered via USB

Reusability Note

This project is a fun and interactive way to visualize sound levels. It can be adapted for other types of sensors or displays, making it a versatile starting point for sound-reactive projects.

What You’ll Need

Hardware

• 1x ESP8266 D1 Mini
• 1x Sound Sensor Module
• 1x Unicorn pHAT RGB LED Matrix
• 1x USB cable (data capable)
• 1x Power supply (USB charger, 5V/1A minimum)

Software

• ESPHome installed
• Home Assistant (optional, for integration)

Future Improvement Ideas

• Add different animation modes based on sound frequency
• Integrate with Home Assistant for sound level logging
• Add a microphone for more precise sound detection

Status

This project is currently in the “idea” stage. The next steps involve setting up the hardware, configuring ESPHome, and designing the LED animations.
