Project Name: To turn LED ON using 8051 Micro-Controller

SOFTWARE: KEIL MICRO VISION 4

SIMULATOR: PROTEUS 8.0

CIRCUIT DIAGRAM:

CIRCUIT WORKING:

This project is about turn on the led which is connected to port 1.0 of port 1.

I have designed this circuit as a current sinking circuit.So in order to turn ON the led I have provided 0V(logic 0) on port 1.0.

PROGRAM:

#include<reg51.h>

sbit led1 = P1^0;

void main()

{

P1=0xfc; // set port 1.0 as output

led1=1; // initially turn off the led

while(1) //continuous loop

{

led1 = 0; // turn on the led1

}

}

PROGRAM DESCRIPTION:

At starting I have make turned off the led by providing logic 1 (port1.0).Then for a continuous process I have used while loop.After that I have turn ON the led by providing logic 0.
