First Arduino program

I know this is underwhelming, but everyone starts somewhere. I threw together a “hello world” type of program for the Arduino I just got. It uses the LED array on the Dragon Rider 500 (check out my Instructable) to scan six LEDs attached to pins 0-5 of the Aduino:

int tracker = 0;
int myDelay = 80;

void setup() {
 for (int i=0; i<6; i++) {
 pinMode(i, OUTPUT);
 }
}

void loop()
{
 digitalWrite(tracker, HIGH);
 delay(myDelay);
 digitalWrite(tracker, LOW);
 if (++tracker > 5) tracker = 0;
}
