// the setup routine runs once when you press reset:
void setup() {
  for(int i = 0; i < 8; i++) {
    pinMode(i, OUTPUT);
  }
}

// the loop routine runs over and over again forever:
void loop() {
  // Display A
  PORTD = 0xEE;
  delay(200);
  // Display L
  PORTD = 0x1C;
  delay(200);
  // Display I
  PORTD = 0x0C;
  delay(200);
