Video 14: Playing Custom Music Note

In this tutorial, you’ll learn how to use the SunFounder ESP32 IoT Learning Kit to play custom musical notes:

  • Passive Buzzer Introduction: Unlike the previous tutorial with an active buzzer, this one uses a passive buzzer which requires an external signal for sound generation.

  • Wiring Guide: Detailed instructions to correctly wire the passive buzzer to the ESP32 module.

  • Buzzer Specifications: The passive buzzer operates on 3 to 5 volts and can produce varying tones based on the input signal frequency.

  • Arduino Code Overview: The tutorial explains how to write and upload code to ESP32 for generating different musical notes through PWM signals.

  • Musical Note Project: Create a setup to play a series of musical notes with the passive buzzer controlled by ESP32.

  • Project Execution: Demonstrates the playing of musical notes once the code is successfully uploaded to the ESP32 module.
