Passive Buzzer Module


thumb


Introduction

We can use Arduino to make many interactive works of which the most commonly used is acoustic-optic display.
The circuit in this experiment can produce sound. Normally, the experiment is done with a buzzer or a speaker while buzzer is simpler and easier to use.
The buzzer we introduced here is a passive buzzer. It cannot be actuated by itself, but by external pulse frequencies. Different frequencies produce different sounds.
We can use Arduino to code the melody of a song, which is quite fun and simple.


Specification

  • Working voltage: 3.3-5v
  • Interface type: digital

Sample Code

int buzzer=3;//set digital IO pin of the buzzer
void setup() 
{ 
pinMode(buzzer,OUTPUT);// set digital IO pin pattern, OUTPUT to be output 
} 
void loop() 
{ unsigned char i,j;//define variable
while(1) 
{ for(i=0;i<80;i++)// output a frequency sound
{ digitalWrite(buzzer,HIGH);// sound
delay(1);//delay1ms 
digitalWrite(buzzer,LOW);//not sound
delay(1);//ms delay 
} 
for(i=0;i<100;i++)// output a frequency sound
{ 
digitalWrite(buzzer,HIGH);// sound
digitalWrite(buzzer,LOW);//not sound
delay(2);//2ms delay 
}
} 
} 


After downloading the program, buzzer experiment is complete. You should hear the buzzer ringing.
