SIMULATOR: PROTEUS 8.0

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.
