Playing with my new Arduino.

I was feeling creative listening to music so I decided to make some sounds.
I went with the song secrets by one republic, a bit inspired by the movie The Sorcerer's Apprentice.

Anyway... This is the result and code:

Code:

#include <pitches.h>

int melody[] = {

  NOTE_D3, NOTE_FS3, NOTE_A3, NOTE_FS3, NOTE_A3, NOTE_FS3, NOTE_D3, NOTE_FS3, NOTE_D3, NOTE_FS3, NOTE_A3, NOTE_FS3, NOTE_A3, NOTE_FS3, NOTE_D3, NOTE_FS3, 

  NOTE_CS3, NOTE_FS3, NOTE_A3, NOTE_FS3, NOTE_A3, NOTE_FS3, NOTE_CS3, NOTE_FS3, NOTE_CS3, NOTE_FS3, NOTE_A3, NOTE_FS3, NOTE_A3, NOTE_FS3, NOTE_CS3, NOTE_FS3, 

  NOTE_B2, NOTE_FS3, NOTE_B3, NOTE_FS3, NOTE_B3, NOTE_FS3, NOTE_B2, NOTE_FS3, NOTE_B2, NOTE_FS3, NOTE_B3, NOTE_FS3, NOTE_B3, NOTE_FS3, NOTE_B2, NOTE_FS3, 

  NOTE_B2, NOTE_G3, NOTE_B3, NOTE_G3, NOTE_B3, NOTE_G3, NOTE_B2, NOTE_G3, NOTE_B2, NOTE_G3, NOTE_B3, NOTE_G3, NOTE_B3, NOTE_G3, NOTE_B2, NOTE_G3, 

};

int noteDurations[] = {

  5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 

  5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 

  5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 

  5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 

};

int leds[] = {

  3, 4, 5, 4, 5, 4, 3, 4, 3, 4, 5, 4, 5, 4, 3, 4,

  3, 4, 5, 4, 5, 4, 3, 4, 3, 4, 5, 4, 5, 4, 3, 4,

  3, 4, 5, 4, 5, 4, 3, 4, 3, 4, 5, 4, 5, 4, 3, 4,

  3, 4, 5, 4, 5, 4, 3, 4, 3, 4, 5, 4, 5, 4, 3, 4,

};

int buttonState = 0;

void setup(){

  Serial.begin(9600); 

  pinMode(2, INPUT);

  pinMode(13, OUTPUT);

  pinMode(3, OUTPUT);

  pinMode(4, OUTPUT);

  pinMode(5, OUTPUT);

  

}

void play(){

  for (int thisNote = 0; thisNote < 64; thisNote++) {

    // to calculate the note duration, take one second

    // divided by the note type.

    //e.g. quarter note = 1000 / 4, eighth note = 1000/8, etc.

    int noteDuration = 1000 / noteDurations[thisNote];

    tone(13, melody[thisNote], noteDuration);

    digitalWrite(leds[thisNote], HIGH);

    Serial.print(melody[thisNote]);

    Serial.println();

    // to distinguish the notes, set a minimum time between them.

    // the note's duration + 30% seems to work well:

    int pauseBetweenNotes = noteDuration * 1.30;

    delay(pauseBetweenNotes);

    digitalWrite(leds[thisNote], LOW);

    // stop the tone playing:

    noTone(13);

  }

}

void loop(){

  // read the state of the pushbutton value:

  buttonState = digitalRead(2);

  // check if the pushbutton is pressed.

  // if it is, the buttonState is HIGH:

  if (buttonState == HIGH) {

    Serial.print(buttonState);

    play();

  } else {

    noTone(13);

  }

}

Hope you enjoy :)
