Turn a Knob to Control Piano Sounds (ESP32 Beginner Project)

In this beginner-friendly class, you’ll learn how to use an ESP32, a knob (adjustable resistor), and a passive buzzer to create simple piano sounds. As you turn the knob, you’ll hear the notes change speed—just like speeding up or slowing down a song! Along the way, you’ll get hands-on experience reading analog input and using it to control sound. No prior experience needed—just curiosity and a willingness to build something fun.

If you have a laptop, please bring it — but come anyway if you don’t!
