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.
