Working voltage: 3.5-5.5V Working current: <25mA PCB Dimension: 18.5mm x 15mm(L x W)
Feature:
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.
Package included:
5 x Standard Passive Buzzer Module
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<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.
