Tujuan : Membuat nada bunyi atau musik 1 oktaf  (tulilut)

Program :  

int speakerPin = 8;

int length = 15; // nomor note

char notes[] = "ccggaag ffeeddc ggffeed ggffeed ccggaag ffeeddc "; // a space represents a rest

int beats[] = { 1, 1, 1, 1, 1, 1, 2, 1, 1, 1, 1, 1, 1, 2, 4 };

int tempo = 300;

void mainTone(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 mainNote(char note, int duration) {

  char names[] = { 'c', 'd', 'e', 'f', 'g', 'a', 'b', 'C' };

  int tones[] = { 1915, 1700, 1519, 1432, 1275, 1136, 1014, 956 };

 

  // memainkan nada yg sesuai

  for (int i = 0; i < 8; i++) {

    if (names[i] == note) {

      mainTone(tones[i], duration);

    }

  }

}

void setup() {

  pinMode(speakerPin, OUTPUT);

}

void loop() {

  for (int i = 0; i < length; i++) {

    if (notes[i] == ' ') {

      delay(beats[i] * tempo); // rest

    } else {

      mainNote(notes[i], beats[i] * tempo);

    }

   

    // berhenti antara note

    delay(tempo / 2);

  }

}
