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!

Push Button Interfacing with PIC Microcontroller [Step by Step]

Basically computer system works on 0 and 1 .Here 0 for GND and 1  for VDD .Consider , we have a resistor which is connected with vdd .So at this state the resistor get '1'. Now connect a push button's one end at the point resistor connected with vdd and another end with ground .In this condition if we press the button , the resistor achieve 0 . It is the main theme . Now we are going to interface push button with Microcontroller and in this tutorial  i am going to use microcontroller PIC 18F2550 .

Proteus Circuit : 

Create a new project  in Proteus and follow the instructions .I am just trying to make easy for every one  .

[Note : If you don't know how to interface LCD  with microcontroller , please follow this tutorial  ] 

(adsbygoogle = window.adsbygoogle || []).push({});

If  you completed those steps , then pick from library  ' pic18f2550' , crystal, 22pf capacitor, 10kohm resistor,5Kohm variable resistor ,power, ground , push button and LCD display( "LM016L" Model  ) according to the instructions given below .

If you got all parts , you can complete the circuit as given below :

In this circuit , we added resistors one end with PORTC and another end added with VDD . Push button's one end connected with PORTC and atother with GND . In this condition pressing the button will make enable 0 state .

Now we need the Source code for this microcontroller .So Create a new Project in MikroC  and follow the instructions :

As it gets 0  ,we can  use this in programming logic and we did it . Now write the source code on mikroC and create .hex file according to the instructions given below :

Now go to Proteus circuit and make a double click on microcontroller to load the .hex file .Please look at the picture given below :
