WLED is an incredible open-source project that turns an ESP32 into a sophisticated LED strip light controller. Capable of working with virtually any type and size of LED strip, this versatile product can be installed and configured without requiring a single line of code. And even better- you can control it with an app, a web-based interface, or even use it with Home Assistant and Alexa!

Today, we will learn everything required for a successful WLED project. We’ll determine the best type of ESP32 for our situation and learn how to select the correct LED strip. Then we will install WLED using its web-based installer and configure it to drive both a NeoPixel LED Strip and an 8×8 addressable LED array.

We’ll also add “Audio Reactive” capability to our setup using a small and inexpensive I2S microphone. Perfect for dancing to the music!
