Bliniking LEDs use PIC Microcontroller and Mikro C
PIC Microcontroller Project : Using PIC16F877A
In this Tutorial we will learn how to blinking LEDs use PIC Microcontroller. Here I am use PIC16F877A Microcontroller and 8MHz quartz crystal. You con watch the following video or read the written tutorial below.
PIC16F877A Microcontroller has A0-A7, B0-B7, C0-C7, D0-D7 and E0-E2 input/output port. Some pins for these I/O port are multiplex with an alternative function for the peripheral feature on the device. In general, when a peripheral is enable, that pin may not used as a general purpose I/O pin.
The TRIS Register controls the direction of Input/Output port. Here PORTB is 8bit wide, bi-directional port. The corresponding data direction register is TRISB. Setting a TRISB bit (= 1) will make the corresponding PORTB pin an Input. Clearing a TRISB bit (=0) will make the corresponding PORTB pin an Output.

Component needed for this Project
Code Explain:
Here I am use Mikro C compiler for code editing. In void main function I define PORTB is output by clearing TRISB register. Then we clear the PORTB register. In next, here I am use while loop for continues program execution and blinking LEDs. And then close the program.
