Automatic Traffic light controller In 8051 C Programming-

#include<stdio.h>

#include<reg51.h>

sbit RA = P1^0;sbit YA = P1^1;sbit GA = P1^2;
sbit rD = P1^3;sbit YD = P1^4;sbit GD = P1^5;
sbit RB = P3^2;sbit YB = P3^3;sbit GB = P3^4;
sbit RC = P3^5;sbit YC = P3^6;sbit GC = P3^7;

void Delay (void)
{
unsigned int a,b;

for (a=0;a<200;a++)
for (b=0;b<500;b++);
}

void SuperDelay()
{
unsigned int a;
for (a=0;a<25;a++)
Delay();
}
void main ()
{
P3 = 0;while (1)
{
RA = 0;GA = 1;YA = 0;RB = 1;
YC = 0;rD = 1;GD = 0;YD = 0;
GB = 0;YB = 0;RC = 1;GC = 0;

SuperDelay();
GA = 0;
YA = 1;
Delay();
RC = 1;GC = 0;YC= 0;
rD = 1;GD = 0;YD = 0;
RA = 1;GA = 0;YA = 0;
RB = 0;GB = 1;YB = 0;

SuperDelay ();

GB = 0;YB = 1;
Delay ();
RA = 1;GA = 0;YA = 0;
RC = 0;GC = 1;YC = 0;
