• Description:
In this video tutorial I show you how to write firmware for the ESP32 (ESP-WROOM-32) to include sounds in your projects. Specifically, I convert standard .wav files using Audacity on my computer, and turn them into byte arrays that can be uploaded to the ESP32. I use a Class-D 2.5W audio amplifier (PAM8302) to drive an 8-ohm speaker to play the sounds!
