Buzzer Piezoelectric Piezo Ceramic Wafer DC 3-24v

Buzzer Piezoelectric Piezo Ceramic Wafer DC 3-24v

The Buzzer Piezoelectric Piezo Ceramic Wafer DC 3-24V is a compact device capable of generating basic beeps and tones. It uses a piezo crystal that changes shape when voltage is applied, producing pressure waves that the human ear perceives as sound. This buzzer is designed for simple applications requiring audible alerts or alarms.

Package Includes:

  • 1x Buzzer Piezoelectric Piezo Ceramic Wafer DC 3-24V

Ceramic Plate Buzzer

Specifications:

  • Operating Voltage: DC 3-24V
  • Type: Continuous sounder electronic buzzer
  • Dimensions: Straight: 23 mm, Height: 11 mm, Pitch: 30 mm

Features:

  • Small size with high-decibel alarm

How to Connect the Buzzer to Arduino:

  1. Connect the piezo wires to the breadboard.
  2. Insert a 100Ω resistor to limit the current to protect the Arduino output pin.
  3. Connect the red wire from the piezo to digital pin 8 on the Arduino.
  4. Connect the black wire from the piezo to one end of the resistor, and connect the other end of the resistor to the Arduino GND (ground) pin.

Arduino Code:


// Specify digital pin connected to positive lead of piezo buzzer
int piezoPin = 8;

void setup() {
  // No setup needed
}

void loop() {
  /* tone() needs 2 arguments, can take 3:
     1) Pin
     2) Frequency in hertz (pitch)
     3) Duration (optional)
  */
  tone(piezoPin, 1000); // Play 1000 Hz tone
  // delay(1000); // Optional delay if you want a pause
}

This code generates a 1000 Hz tone on pin 8. You can change the frequency by modifying the value inside the tone() function.
