Happy Birthday Song Using Arduino Uno

Hello friends welcome back to “Techno-E-solution” in todays article I’ll show “How to play Happy Birthday Song Using Arduino & Buzzer” in few steps. Most of the peoples are from technical background so I decide to wish that peoples means my besties in techy style so build this project. This is a beginners level project so let’s make it.

Step 1: MATERIAL REQUIRED

To make this project we need some components (Best Buy Link Provided):-

1. Arduino Uno X 1
2. Buzzzer X 1

[ Above link are affiliated if you buy from above link, We got some bonus from it. ]

Step 2: CIRCUIT DIAGRAM

Follow the circuit diagram to make the connection.

Arduino >>> Buzzer

D8 >>> +ve

GND >>> -ve

Step 3: ARDUINO CODE

/*
 Hello Friends Welcome to Techno-E-Solution
 Here is the Code For Happy Birthday Song
 */

int speakerPin = 8;
int length = 28; // the number of notes
char notes[] = "GGAGcB GGAGdc GGxecBA yyecdc";
int beats[] = { 2, 2, 8, 8, 8, 16, 1, 2, 2, 8, 8,8, 16, 1, 2,2,8,8,8,8,16, 1,2,2,8,8,8,16 };
int tempo = 150;
void playTone(int tone, int duration) {
for (long i = 0; i < duration * 1000L; i += tone * 2) {
   digitalWrite(speakerPin, HIGH);
   delayMicroseconds(tone);
   digitalWrite(speakerPin, LOW);
   delayMicroseconds(tone);
}
}
void playNote(char note, int duration) {
char names[] = {'C', 'D', 'E', 'F', 'G', 'A', 'B',           

                 'c', 'd', 'e', 'f', 'g', 'a', 'b',

                 'x', 'y' };

int tones[] = { 1915, 1700, 1519, 1432, 1275, 1136, 1014,

                 956,  834,  765,  593,  468,  346,  224,

                 655 , 715 };

int SPEE = 5;
// play the tone corresponding to the note name
for (int i = 0; i < 17; i++) {
   if (names[i] == note) {
    int newduration = duration/SPEE;
     playTone(tones[i], newduration);

   }
}
}

void setup() {
pinMode(speakerPin, OUTPUT);
}
void loop() {
for (int i = 0; i < length; i++) {
   if (notes[i] == ' ') {
     delay(beats[i] * tempo); // rest
   } else {
     playNote(notes[i], beats[i] * tempo);
   }
   // pause between notes
   delay(tempo);
}
}
