This project shows how to use any speaker as a buzzer.
What I made
The main sketch for the Arduino speaker is the first one.
Next, you have to create a new pitches.h file. To make that, either click on the button just below the serial monitor icon and choose "New Tab", or use Ctrl+Shift+N. Then paste in the following code.(2)
#include"pitches.h"
int melody[] = {
NOTE_D4, NOTE_G4, NOTE_FS4, NOTE_A4,
NOTE_G4, NOTE_C5, NOTE_AS4, NOTE_A4,
NOTE_FS4, NOTE_G4, NOTE_A4, NOTE_FS4, NOTE_DS4, NOTE_D4,
NOTE_C4, NOTE_D4,0,
NOTE_D4, NOTE_G4, NOTE_FS4, NOTE_A4,
NOTE_G4, NOTE_C5, NOTE_D5, NOTE_C5, NOTE_AS4, NOTE_C5, NOTE_AS4, NOTE_A4, //29 //8
NOTE_FS4, NOTE_G4, NOTE_A4, NOTE_FS4, NOTE_DS4, NOTE_D4,
NOTE_C4, NOTE_D4,0,
NOTE_D4, NOTE_FS4, NOTE_G4, NOTE_A4, NOTE_DS5, NOTE_D5,

NOTE_D4, NOTE_FS4, NOTE_G4, NOTE_A4, NOTE_DS5, NOTE_D5,
NOTE_C5, NOTE_D5, NOTE_C5, NOTE_AS4, NOTE_C5, NOTE_AS4, NOTE_A4, NOTE_C5, NOTE_G4,

NOTE_C4, NOTE_D4, 0,
NOTE_C4, NOTE_D4, NOTE_G4, NOTE_FS4, NOTE_DS4,
NOTE_C4, NOTE_D4, END
};
// note durations: 8 = quarter note, 4 = 8th note, etc.
int noteDurations[] = { //duration of the notes

int speed=90; //higher value, slower notes
void setup() {
Serial.begin(9600);
for (int thisNote = 0; melody[thisNote]!=-1; thisNote++) {
int noteDuration = speed*noteDurations[thisNote];
tone(3, melody[thisNote],noteDuration*.95);
Serial.println(melody[thisNote]);
delay(noteDuration);
