Arduino & Buzzer ile Melodi Projesi

 

 Sevgili Öğrenciler,

Arduino robotik setinizle aşağıdaki referans kodları da Arduino programında yazarak Buzzer ile melodi çalma projesi  yapıyoruz.

Projede Kodla Türkiye Robotik setindeki Shielde entegre  buzzer ile "Yeniyıl Jingle Bells Melodisi"  kodlanıp çalınacaktır.

Başarılar!

//Arduino Referans Kaynak Kodu:

// * Jingle Bells
 

// TONES  ==========================================  

  
 //       note, period, &  frequency.
 #define  C     2100
 #define  D     1870 
 #define  E     1670
 #define  f     1580    // Does not seem to like capital F
 #define  G     1400 
 // Define a special note, 'R', to represent a rest
 #define  R     0
 // SETUP ============================================
 

 int speakerOut = 5;

 int DEBUG = 1;
 void setup() {
   pinMode(speakerOut, OUTPUT);
   if (DEBUG) {
     Serial.begin(9600); // Set serial out if we want debugging
   }
 }
 // MELODY and TIMING  =======================================
 //  melody[] is an array of notes, accompanied by beats[],
 //  which sets each note's relative length (higher #, longer note)
 int melody[] = {E, E, E,R,
 E, E, E,R,
 E, G, C, D, E, R,
 f, f, f,f, f, E, E,E, E, D ,D,E, D, R, G ,R,
 E, E, E,R,
 E, E, E,R,
 E, G, C, D, E, R,
 f, f, f,f, f, E, E, E,  G,G, f, D, C,R };
 int MAX_COUNT = sizeof(melody) / 2; // Melody length, for looping.
 // Set overall tempo
 long tempo = 10000;
 // Set length of pause between notes
 int pause = 1000;
 // Loop variable to increase Rest length
 int rest_count = 100; //<-BLETCHEROUS HACK; See NOTES
 // Initialize core variables
 int tone_ = 0;
 int beat = 0;
 long duration  = 0;

 // PLAY TONE  ==============================================
 // Pulse the speaker to play a tone for a particular duration
 void playTone() {
   long elapsed_time = 0;
   if (tone_ > 0) { // if this isn't a Rest beat, while the tone has
     //  played less long than 'duration', pulse speaker HIGH and LOW
     while (elapsed_time < duration) {
       digitalWrite(speakerOut,HIGH);
       delayMicroseconds(tone_ / 2);
       // DOWN
       digitalWrite(speakerOut, LOW);
       delayMicroseconds(tone_ / 2);
       // Keep track of how long we pulsed
       elapsed_time += (tone_);
     }
   }
   else { // Rest beat; loop times delay
     for (int j = 0; j < rest_count; j++) { // See NOTE on rest_count
       delayMicroseconds(duration); 
     } 
   }                                
 }
  
 void loop() {
  for (int i=0; i<MAX_COUNT; i++) {
    tone_ = melody[i];
    beat = 50;

    duration = beat * tempo; // Set up timing

    playTone();
    // A pause between notes...
    delayMicroseconds(pause);
  }
 }
