Using Buzzer For Output

Introduction

Arduino is often used with input and output peripherals. Common output components used with Arduino in mini-projects are LED and Buzzer. Similarly, a potentiometer is a commonly used input device for analog input to Arduino. In this article, we will dive into understanding these components and making exciting mini projects using these.

Using Buzzer For Output

Circuit Diagram:

 

Software Setup:

	// Pin connected to buzzer
	int buzzer = 5;
	void setup()
	{
	// Defines the Buzzer pin as output
	pinMode(buzzer,OUTPUT);
	}
	void loop()
	{
	for(int i = 0; i<= 1023; i++)
	tone(buzzer,i*4,1000); //Output buzzer for read frquency input fo 1 second
	}
