2.14 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.
