Sound Reactive Lights Tutorial

Materials List

• Arduino – I'm using the Limited Edition Arduino Uno Mini
• Microphone Sensor
• RGB LED Strip (WS2812B)

2. Install FastLED Library

This code uses the FastLED library to control LED lights. The library can be installed from the Arduino IDE by going to Sketch > Include Library > Manage Libraries. Then search for FastLED by Daniel Garcia and click Install.

3. Upload Code

Open the sound-reactive-lights.ino file and upload the code onto the Arduino board!
