Introduction
In this tutorial, we will learn about the KY-006 module, what is a passive piezoelectric buzzer, and we will build a simple project to music using the KY-006 module and an Arduino.
Small Passive Buzzer Module KY-006
The KY-006 Module will be our main component for this tutorial. This module has a passive piezoelectric buzzer mounted on a breakout board. Figure 1 shows the module as seen in fritzing.
Pinout
The KY-006 module has three pins.
| Component Pin | Arduino Uno board Pin |
|---|---|
| (-) | GND |
| middle | +5V |
| S | Signal |
What is a Passive Piezoelectric Buzzer?
A passive piezoelectric buzzer is a kind of buzzer that uses the piezoelectric effect to produce sound. By applying a voltage to the buzzer terminals, a metal plate vibrates producing a tone.
Project - Arduino Simple Tone Player
After learning about the KY-006 module and the passive piezoelectric buzzer, it is now time to build a project using the module. Our project will play tones using the KY-006 module and an Arduino.
Components
For this project, we need the following components:
- Arduino Uno board (1 pc.)
- KY-006 Small Passive Buzzer Module (1 pc.)
- Jumper wires
Wiring Diagram
Figure 2 shows the connection between the Arduino Uno and the KY-006 Small Passive Buzzer Module.
The KY-006 module pins are connected to the Arduino Uno board as follows:
| Component Pin | Arduino Uno board Pin |
|---|---|
| (-) | GND |
| middle | +5V |
| S | 10 |
The Code
// Arduino and KY-006 module
void setup() {
// nothing to do here
}
void loop() {
int buzzer = 10; // module connected to pin 10 of Arduino
// play a melody to the KY-006 module
tone(buzzer, 262, 250); // play a tone
delay(325); // pause code
noTone(buzzer); // stop playing tone
tone(buzzer, 196, 125);
delay(162);
noTone(buzzer);
tone(buzzer, 196, 250);
delay(325);
noTone(buzzer);
tone(buzzer, 220, 250);
delay(325);
noTone(buzzer);
tone(buzzer, 196, 250);
delay(325);
noTone(buzzer);
tone(buzzer, 0, 250);
delay(325);
noTone(buzzer);
tone(buzzer, 247, 250);
delay(325);
noTone(buzzer);
tone(buzzer, 262, 250);
delay(325);
noTone(buzzer);
delay(1000);
}
Project Test
Apply power to your Arduino Uno board. You will hear a melody play on the KY-006 module and will repeat it indefinitely.
