20Pcs 35 55V Standard Passive Buzzer Module For Arduino

Specification : 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 : 20 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 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.
