Introduction
 
We can use Aduino to make many interactive works of which the most commonly used is acoustic-optic display. All the previous experiment has something to do with LED. However, 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 Aduino to code the melody of a song, which is actually quite fun and simple.
 
Specification 
  • Working voltage: 3.3-5v
  • Interface type: digital

Sample Code:

int buzzer=8;//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 finished.
