Working current: ( semnul mai mic ) 25mA

Buzzer introduction:

1. Buzzer is an integrated structure electronic transducers, DC voltage supply, widely used in computers , printers, copiers , alarms, electronic toys, automotive electronic equipment , telephones, timers and other electronic products for sound device .

2 . Piezo buzzer divided into electromagnetic buzzer and buzzer.

3 . The buzzer in the circuit use the letter "H" or "HA" ( old standard with "FM", "LB", "JD" , etc. ) indicates .

Structural principle:

1.Piezo buzzer mainly by multivibrator, piezo buzzer , impedance matching and resonance box , casing and other components.
Some piezo buzzer case is equipped with light-emitting diodes.

2.Multivibrator constituted by the transistors or integrated circuits.

When switched on (1.5 ~ 15V DC working voltage ) , multi-harmonic oscillator start-up , the output 1.5 ~ 2.5kHZ audio signals , impedance matching push piezo buzzer sound.

3. Electromagnetic buzzer from the oscillator, the electromagnetic coils, magnets, and other components diaphragm and the housing . After power on , the audio signal generated by the oscillator current through the electromagnetic coil , the electromagnetic coil generates a magnetic field . The electromagnetic coil and the diaphragm is the interaction of the magnet, periodically vibrating sound.

ARDUINO reference source programme:

int buzzer=8;// Set the control the buzzer digital IO pin
void setup()
{
pinMode(buzzer,OUTPUT);// Setting the digital IO pin mode , OUTPUT is Wen out
}
void loop()
{
unsigned char i,j;// Define the variable
while(1)
{
for(i=0;i ( semnul mai mic ) 80;i++)// Wen a frequency sound
{
digitalWrite(buzzer,HIGH);// Sound
delay(1);//delay 1ms
digitalWrite(buzzer,LOW);//Not sound
delay(1);// delay 1ms
}
for(i=0;i ( semnul mai mic ) 100;i++)// Wen out another frequency sound
{
digitalWrite(buzzer,HIGH);// Sound
delay(2);//delay 2ms
digitalWrite(buzzer,LOW);// Not sound
delay(2);//delay 2ms
}
}
}
After downloading the program, the buzzer experiments are finish.
