About Buzzer
What is Buzzer?
In Arduino projects, a buzzer or piezo speaker is a simple and effective component that can generate audible tones and sounds. A buzzer may provide your electronic inventions with an audible element, whether you want to use it to make beeps, alarms, or tunes. We’ll look at connecting and managing a buzzer with an Arduino microcontroller in this lesson.
Types of Buzzers
There are five types of Buzzer as follows:
- Piezoelectric Buzzers
- Magnetic Buzzers
- Electromagnetic Buzzers
- Mechanical Buzzers
- Electromechanical Buzzers
Applications of Buzzer
Buzzers are used in
- Automotives
- Trains
- Alarm systems
- Timers etc.
How to Use Buzzer with Arduino?
Introduction
A buzzer is a small but powerful device that can make your projects beep, sing, or even play music. By following the steps in this article, you’ll learn how to connect a buzzer to your Arduino, write simple code, and create your very own tunes. It’s a fun and engaging way to add another layer of creativity to your projects. We are using three buzzers with Arduino in this project.
Components
We will need these components to do this project.
- Three Buzzers
- Jumper Wires
- Three 100 ohm Resistors
- Arduino Board
- USB cable
Circuit Diagram of Arduino with Buzzer
Below shows the hardware and circuit connection on this topic.
Code
int pos = 0;
void setup()
{
pinMode(8, OUTPUT);
pinMode(6, OUTPUT);
pinMode(7, OUTPUT);
}
void loop()
{
// turn off tone function for pin 8:
noTone(8);
// play a note on pin 6 for 200 ms:
tone(6, 880, 200); // play tone 69 (A5 = 880 Hz)
delay(200); // Wait for 200 millisecond(s)
// turn off tone function for pin 6:
noTone(6);
// play a note on pin 7 for 500 ms:
tone(7, 988, 500); // play tone 71 (B5 = 988 Hz)
delay(500); // Wait for 500 millisecond(s)
// turn off tone function for pin 7:
noTone(7);
// play a note on pin 8 for 300 ms:
tone(8, 1047, 300); // play tone 72 (C6 = 1047 Hz)
delay(300); // Wait for 300 millisecond(s)
