Video 13: Arduino Beep with Active Buzzer

Here, you will learn how to use an active buzzer with the ESP32 module for generating sound:

• Active Buzzer Introduction: Learn to control an active buzzer using a transistor. The buzzer emits sound when powered up.

• Buzzer Components: The tutorial uses an active buzzer, a 1K resistor, jumper wires, and an S8050 transistor.

• Wiring and Schematic: Understand the wiring schematic for connecting the buzzer to the ESP32.

• Buzzer Specifications: The active buzzer operates within a voltage range of 3 to 8 volts and has an internal oscillating frequency of around 2700 Hz.

• Arduino Programming: The tutorial covers the setup, loop functions, and how to control the buzzer using digital signals.

• Interactive Project: The project demonstrates how to generate a beeping sound with the buzzer, controlled by the ESP32.

• Demonstration: Once the code is uploaded, the ESP32 module activates the buzzer, producing a beeping sound.
