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 :
//////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
(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.
Thank You!
