Piezo Transducer Module Arduino Compatible

This piezo transducer module is perfect for interactive Arduino projects, allowing your project to have audible feedback. The main advantage of a piezo transducer is its ability to produce sound at different tones and frequencies.

Test Code

int buzzer = 8; // setting controls the digital IO foot buzzer

void setup() {
pinMode(buzzer, OUTPUT); // set the digital IO pin mode, OUTPUT out of Wen
}

void loop() {
unsigned char i, j; // define variables

while (1) {
for (i = 0 ; i < 80; i++) { // Wen a frequency sound
digitalWrite(buzzer, HIGH); // send voice
delay(1); // Delay 1ms
digitalWrite(buzzer, LOW); // do not send voice
delay(1); // delay ms
}

for(i = 0; i < 100; i++) { // Wen Qie out another frequency sound
digitalWrite(buzzer, HIGH); // send voice
delay(2); // delay 2ms
digitalWrite(buzzer, LOW); // do not send voice.
delay(2); // delay 2ms
}
}
