Passive Piezo Buzzer Module for Arduino 3.3V – 5V

Description

Required Hardware Devices

• Arduino controller × 1
• Passive Piezo Buzzer Module
• USB data cable × 1

Connecting

Arduino digital pin 8 –> pin ‘I/O’ of module
Arduino GND –> Pin ‘-‘ of module
Arduino +5 –> Pin ‘VCC’ of module

Code

//Example Code for KY-006
 
int buzzer = 8 ;// setting controls the digital IO foot buzzer
void setup ()
{
  pinMode (buzzer, OUTPUT) ;// set the digital IO pin mode, OUTPUT out of Wen
}
void loop ()
{
  unsigned char i, j ;// define variables
  while (1)
  {
    for (i = 0; i <80; i++) // Wen a frequency sound
    {
      digitalWrite (buzzer, HIGH) ;// send voice
      delay (1) ;// Delay 1ms
      digitalWrite (buzzer, LOW) ;// do not send voice
      delay (1) ;// delay ms
    }
    for (i = 0; i <100; i++) // Wen Qie out another frequency sound
    {
      digitalWrite (buzzer, HIGH) ;// send voice
      delay (2) ;// delay 2ms
      digitalWrite (buzzer, LOW) ;// do not send voice
      delay (2) ;// delay 2ms
    }
  }
}
