50 x Standard Passive Buzzer Module

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
for(i=0;i<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<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.
