Detailed Description:

Add a simple, effective audio alarm or user feedback signal to your projects with the 5V DC Active Buzzer Module. This compact, 12mm piezoelectric sound alarm is the ideal choice for any electronics enthusiast, student, or professional seeking a straightforward way to incorporate sound into their circuits. Unlike a passive buzzer that requires a complex alternating signal to generate a tone, this active buzzer features a built-in oscillation circuit. This internal driver allows the buzzer to produce a clear, single-tone sound the moment it receives a constant DC voltage.

The module is incredibly easy to use, functioning just like an LED. You can simply connect it to a digital pin of an Arduino or other microcontroller and program it to turn ON or OFF with a simple command. This eliminates the need for complex timing or PWM (Pulse Width Modulation) functions, making your code cleaner and your project assembly much faster.

Designed to operate on a standard voltage range of 3.5V to 5.5V DC, this buzzer is fully compatible with most development boards. It produces a loud, attention-grabbing sound, typically at a frequency of 2.5 kHz, with a sound pressure level of over 85 dB. This makes it perfect for a wide range of applications, including:

• Alarms and Warning Systems: In security devices, timers, and home automation.

• User Interface: Providing audible feedback for button presses or sensor triggers.

• Educational Projects: Serving as a straightforward output component in robotics and DIY kits.

With its simple interface, high-quality audio output, and durable design, the 5V DC Active Buzzer Module is a fundamental component for any electronics project, that needs a quick and reliable audio signaling solution.

The 5V DC Buzzer Module is a compact, active buzzer that generates sound when 5V power is applied — no PWM or tone signal required. It features a built-in oscillating circuit, which means it sounds continuously when powered via a digital HIGH signal.

This makes it ideal for use in security alarms, warning systems, timers, buzzers, and user feedback systems. It can be connected directly to digital output pins of most development boards, making it very easy to integrate into a wide range of DIY and professional applications.

How to Use with Arduino:

#define BUZZER 8  // Connect buzzer signal to digital pin 8

void setup() {
  pinMode(BUZZER, OUTPUT);
}

void loop() {
  digitalWrite(BUZZER, HIGH);  // Turn buzzer ON
  delay(500);                  // Wait 0.5 seconds
  digitalWrite(BUZZER, LOW);   // Turn buzzer OFF
  delay(500);                  // Wait 0.5 seconds
}

Use a current-limiting resistor if needed for protection.
