🔔 Passive Buzzer Module – 5V for Arduino, with Driver Circuit

📝 Overview

The Passive Buzzer Module is a compact plug-and-play component designed to easily generate tones, melodies, and alerts when used with a microcontroller like Arduino or ESP32. Unlike active buzzers, this passive buzzer requires a PWM or square wave signal, giving you full control over the pitch and duration of sound.

⚙️ Key Features

• Operating Voltage: 3.3V to 5V

• Built-in transistor driver for direct connection to Arduino digital pins

• Passive buzzer type – tone frequency controlled by code

• PCB-mounted module with header pins for easy prototyping

• Onboard marking for VCC, GND, and signal (S)

• Compact and breadboard-friendly design

📦 Technical Specifications

🛠️ Wiring with Arduino Uno

🧪 Sample Code

cpp
CopyEdit
void setup() {
  pinMode(8, OUTPUT);
}

void loop() {
  tone(8, 1000); // Play 1kHz tone on pin 8
  delay(500);
  noTone(8);     // Stop tone
  delay(500);
}

🎯 Common Applications

• Arduino sound effects

• Alarm and alert systems

• Melody generation in interactive projects

• Timers and status indicators
