This circuit is designed with the help of Proteus software.

PIC16F877A Circuit

1. Open the Proteus software. A window with a menu bar appears.

2. Click the file menu.

3. Select ‘new design’ from the drop-down menu.

4. Click the library menu.

5. Select ‘pick devices/symbol’ from the drop-down menu.

6. Select the relevant comment by double-clicking it, so that the list of the electronic components appears on the window.

7. Add all the components and draw the circuit with the proper connections as shown above.

The PIC microcontroller programming is performed through ‘MP-Lab’ software. First, we need to do is to install the MP-Lab software, then select and install the compiler like CCS, GCC compiler, etc. Here ‘The CCS C compiler is used for building the program.

1. First, open the MPLAB software. This shows the menu bar with file, edit, view, project, and tools options.

2. Select the project option and select the ‘project wired option’ from the drop-down menu. This will show the project wired window.

3. Select a microcontroller for your project. Here ‘PIC16f877A’ microcontroller is selected.

4. Select the compiler and path location for your project. Here  ‘The CCS C compiler is selected for the PIC microcontroller, then select the ‘browse’ option from the project wired window to select the ‘ccsloader’ in the PICC  folder from the program files.  A folder with the name ‘source group’ is created in the ‘target’ folder.

5. Give a name to the project and click on the ‘NEXT’ button to save the project. A folder with the name ‘source group’ is created in the ‘target’ folder. Click on the ‘file’ menu on the menu bar. Select ‘new file’ from the drop-down menu.
