Create Musical Tone Using PIC Microcontroller[Step by Step ]

In this tutorial , i will show how to create melody using microcontroller and in this tutorial i will use pic18f2550 microcontroller .So let's create a project in proteus .

Proteus Project :

Please follow the instructions given below :

 

Now pick pic18f2550, sounder, crystal,22pf capacitor,VDD and ground according to the instructions given below :

Now complete the circuit as given below :

MikroC Code :

Now  we need the source code .So create a project in MikroC and follow the instructions given below:

Source Code :

//////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////

void Tone1() {
  Sound_Play(659, 250);   // Frequency = 659Hz, duration = 250ms
}

void Tone2() {
  Sound_Play(698, 250);   // Frequency = 698Hz, duration = 250ms
}

void Tone3() {
  Sound_Play(784, 250);   // Frequency = 784Hz, duration = 250ms
}

void Melody() {           // Plays the melody "Yellow house"
  Tone1(); Tone2(); Tone3(); Tone3();
  Tone1(); Tone2(); Tone3(); Tone3();
  Tone1(); Tone2(); Tone3();
  Tone1(); Tone2(); Tone3(); Tone3();
  Tone1(); Tone2(); Tone3();
  Tone3(); Tone3(); Tone2(); Tone2(); Tone1();
}

void ToneA() {
  Sound_Play( 880, 50);
}
void ToneC() {
  Sound_Play(1046, 50);
}
void ToneE() {
  Sound_Play(1318, 50);
}

void main() {
    ADCON1=0x0F;   //disable adc
    CMCON=7;         //disable comparator



  Sound_Init(&PORTC,0);
  Sound_Play(880, 1000);             // Play sound at 880Hz for 1 second

  while (1) {
  ToneA();
  delay_ms(100);
  ToneC();
   delay_ms(100);
  ToneE();
   delay_ms(100);
  Melody();


  }
}

Now follow the next instructions .

.

Now just run the project.

Thank You!
