Making Sound In Arduino

Introduction

 

In this article, I'm going to explain about making sound in the Arduino, using the push button.

 

Parts Of Lists

• Arduino Uno
• Push Button
• Buzzer
• Bread Board
• Hookup Wire. 

Connection

• Push Button To Board:
• Connect the 1st pin of the VCC of 5v to the Arduino Board
• Connect the 2nd pin to the Gnd and any digital pin of the input side to the Board.

Buzzer to Board

• Connect one side of the wire to the VCC
• Connect the another side of the wire to the Gnd. 

Programming

#include "pitches.h"
const int buttonPin = 2; // the number of the pushbutton pin
int note1 = NOTE_C4; // define note sound
// variables will change:
int buttonState = 0; // variable for reading the pushbutton status
void setup() {
    // initialize the pushbutton pin as an input:
    pinMode(buttonPin, INPUT);
}
void loop() {
    // read the state of the pushbutton value:
    buttonState = digitalRead(buttonPin);
    // check if the pushbutton is pressed.
    // if it is, the buttonState is HIGH:
    if (buttonState == HIGH) {
        // sound tone
        tone(8, note1);
    } else {
        //turn off sound
        noTone(8);
    }
}

That's it. Now, when the button is pressed, it will automatically produce the sound.
