Description
KY-006 SPECIFICATIONS
This module consists of a passive buzzer and 3 male header pins. You can use it generate tones between 1.5 to 2.5kHz by switching it on and off repeatedly at different frequencies either using delays or PWM.
| Operating Voltage | 1.5V ~ 15V DC |
| Tone Generation Range | 1.5kHz ~ 2.5kHz |
| Board Dimensions | 18.5mm x 15mm [0.728in x 0.591in] |
CONNECTION DIAGRAM
Connect the module signal (S) to pin 8 on the Arduino and ground (-) to GND.
The middle pin is not used.

KY-006 ARDUINO CODE
The following Arduino sketch will generate two different tones by rapidly turning on and off the 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 < 100; 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(500);
