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 .
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 :
Now we need the source code .So create a project in MikroC and follow the instructions given below:
//////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
(adsbygoogle = window.adsbygoogle || []).push({});
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.
