Blinking LED using PIC microcontroller PIC16F877A and Proteus simulation

Before Going to this PIC16F877A LED blinking tutorial, we are recommending you to see how to configure a pin in PIC microcontroller PIC16F877A as input or outtput. From the link below

If you have learned how to configure the PIN as a output using TRIS directio register. You can go forward to use it in a application. i.e., Blinking LED using PIC16F877A pic microcontroller.

PICF16F877A Blinking LED Circuit (Proteus)

In this circuit Oscillator frequency is used as 8MHz. and a RA0 is connected to the LED through a 400 ohm resistor.

Embedded C Program

#include <xc.h>
void main(void) {
    //PORTA pin 0 as output
    TRISA0 = 0;
    //Initialize the variable
    int i = 0;
    //loop for ever
       //LED ON
       RA0 = 1;
       for(i = 1; i< 6000; i++);
       //LED OFF
       RA0 = 0;
       for(i = 1; i< 6000; i++);    

PIC16F877A blinking LED Proteus Output

Whenever the RA0 is high LED will blink, and when it is low it will not blink. A small delay is given to visually see the led blink in a real world.
