3.5-5.5V Standard Passive Buzzer Module For Arduino
Working voltage: 3.5-5.5V
Working current: <25mA
No oscillation source, need square wave (frequency 2K-5K ) to drive.
Sound frequency control, you can make a "do re mi fa sol la si" effect.
1 x Standard Passive Buzzer Module
ARDUINO reference source programme:
int buzzer=8;// Set the control the buzzer digital IO pin
pinMode(buzzer,OUTPUT);// Setting the digital IO pin mode , OUTPUT is Wen out
unsigned char i,j;// Define the variable
for(i=0;i<80;i++)// Wen a frequency sound
delay(1);// delay 1ms
for(i=0;i<100;i++)// Wen out another frequency sound
digitalWrite(buzzer,LOW);// Not sound
After downloading the program, the buzzer experiments are finish.
