Active Buzzer Beep Demo

This project demonstrates how to control an active buzzer module with an Arduino Uno. The active buzzer generates a fixed-frequency tone whenever the signal pin is driven HIGH. The code repeatedly turns the buzzer on and off to create a simple beeping alert pattern.

Active Buzzer Beep Demo with ESP32

This project demonstrates how to control an active buzzer module using an ESP32. The sketch turns the buzzer on and off in a repeating beep pattern while outputting the current state to the Serial Monitor.
