it is a simple sample FOR LOOP program for arduino board, just YOU have to connect the leds with pin 13 and than coming down upto pin 9. Than run and see the result....

1. void setup() {
for (int pin=13; pin> 8; pin--)
{ pinMode ( pin, OUTPUT);
}
}
void loop() {
for (int pin=13; pin> 8; pin--)
{ digitalWrite (pin, HIGH);
delay(250);
digitalWrite(pin,LOW);
}
for (int pin=9; pin< 14; pin++)
{digitalWrite (pin, HIGH);
delay(250);
digitalWrite(pin,LOW);
}
}
