#include "pitches.h" // including the library with the frequencies of the note 

int melody[] = {
  NOTE_C4, NOTE_A3, NOTE_A3, NOTE_C4, NOTE_D4, NOTE_G3, NOTE_G3, NOTE_A3, NOTE_AS3, NOTE_F4, NOTE_F4, NOTE_E4, NOTE_C4, NOTE_D4, NOTE_C4, NOTE_AS3, NOTE_A3, NOTE_C4, NOTE_D4, NOTE_D4

}; // declaring the duration of each note (4 is a quarter note ecc)

int songLength = sizeof(melody)/sizeof(melody[0]); // defining the song length, in this case it is equal to the length of the melody

void setup () {
    for (int thisNote = 0; thisNote < songLength; thisNote ++) {
    int duration = 1000/ durations[thisNote];
    tone(8, melody[thisNote], duration);
    int pause = duration * 1.5; // adding a little delay in between each note to separate the sounds
    delay(pause);
    noTone(8);
}
}
void loop() {
  // no need to loop the melody
}

Pitches Library

C/C++
This is the pitches library you'll need for the buzzer to play each frequency of the notes. To use it you'll need to create another tab using the little arrow in the upper right of the screen.
