KY-006 Passive Buzzer Module

Arduino Passive Piezoelectric Buzzer Module Keyes KY-006, it can produce a range of sound tones depending on the input frequency.

The KY-006 Buzzer Module consists of a passive piezoelectric buzzer, it can generate tones between 1.5 to 2.5 kHz by switching it on and off at different frequencies either using delays or PWM.

Connect signal (S) to pin 8 on the Arduino and ground (-) to GND. The middle pin is not used.

The following Arduino sketch will generate two different tones by turning on and off the KY-006 buzzer at different frequencies using a delay.

int buzzer = 8; // set the buzzer control digital IO pin

void setup() {
	pinMode(buzzer, OUTPUT); // set pin 8 as output
}

void loop() {
	for (int i = 0; i < 80; i++) {  // make a sound
		digitalWrite(buzzer, HIGH); // send high signal to buzzer 
		delay(1); // delay 1ms
		digitalWrite(buzzer, LOW); // send low signal to buzzer
		delay(1);
	}
	delay(50);
	for (int j = 0; j < 100; j++) { //make another sound
		digitalWrite(buzzer, HIGH);
		delay(2); // delay 2ms
		digitalWrite(buzzer, LOW);
		delay(2);
	}
	delay(100);
}
