#include <stdio.h> 
int main() 
{ 
        int i; 
        pcf8574Setup(100,0x27);                                  
        for(i=0;i<8;i++) pinMode(100+i,OUTPUT);

        { 
                i = 0; 
                for(i=0;i<=8;i++)                                             
                {

                        digitalWrite((100+i),HIGH);                       
                        delay(500);
