PCB Mounted Passive Buzzer Module

Description

Passive Buzzer Module is a built-in construction of digital transducers, DC energy provides, extensively utilized in computer systems, printers, copiers, alarms, digital toys, car digital apparatus, phones, timers and different digital electronics projects for Alert sound.

This PCB Mounted Passive Buzzer Module can produce a range of sound tones depending on the input frequency, i.e it can generate tones between 1.5 to 2.5 kHz by switching it on and off at different frequencies either using delays or PWM.

The following Arduino Sample sketch will generate two different tones by turning on and off the buzzer at different frequencies using a delay.

int buzzer = 8; // set the buzzer control digital IO pin 
void setup() { 
pinMode(buzzer, OUTPUT); // set pin 8 as output
 }
void loop() { 
for (int i = 0; i < 80; i++) { 
     digitalWrite(buzzer, HIGH); // make a sound
     delay(1); // send high signal to buzzer
     digitalWrite(buzzer, LOW); // delay 1ms
     delay(1); // send low signal to buzzer 
                             }
 delay(50);
 for (int j = 0; j < 100; j++) { 
     digitalWrite(buzzer, HIGH);  //make another sound 
     delay(2);
     digitalWrite(buzzer, LOW); // delay 2ms 
     delay(2);
                               }
 delay(100); 
}
