[Solved] LED bar...but inverted !?

:-?

hi all, im new here , new world of microcontrollers.
so did do; bought arduino board play around with. nothing difficult, nothing specific.

so found knight rider thingie on forum somewhere in old topic. upped code arduino, wired leds n resistors way should and......

....the leds light up, , knight rider effect running...but inverted. mean there should light running left right , vice versa....but in case al lights on , 1 goes off left right , vice versa...

this code used...:

code: [select]

int ledpin[] ={3,5,6,9,10,11};
int n = 0; //speed counter.
int =0; // repeater.
int value[] ={0,0,0,0,0,0};

void setup()
{
}

void loop()
{
 if(n == 100){value[0]=255;}
 if(n == 200){value[0]=255;}
 if(n == 300){value[1]=255;}
 if(n == 400){value[2]=255;}
 if(n == 500){value[3]=255;}
 if(n == 600){value[4]=255;}
 if(n == 700){value[5]=255;}
 if(n == 800){value[5]=255;}
 if(n == 900){value[4]=255;}
 if(n == 1000){value[3]=255;}
 if(n == 1100){value[2]=255;}
 if(n == 1200){value[1]=255;}
 if(n >= 1200){n =0;}
 
 
 for (i  = 0; <=5; i++)
 {
   if(value[i] >= 5){ value[i]-=1;}
   else if (value[i] < 5) { value[i]=0;}
 }

(i  = 0; <=5; i++)
  {
    analogwrite(ledpin[i], value [i]);
  }
  n+=5;
  delay(5);
}





examples:

this have

this should be

so code works , hardware connected properly...what can fix ?

this pretty crufty because don't "get" code that's there if lights opposite of want, change analogwrite 255-value .  may not clean maybe move along.
