Knight Rider (Brute Force)

Knight Rider

The Knight Rider effect is interesting way to make LEDs create a back and forth LED pattern. The code can be shortened and is more flexible using an array to control the effect.

void setup() 
{

  pinMode(8, OUTPUT);
  pinMode(9, OUTPUT);
  pinMode(10, OUTPUT);
  pinMode(11, OUTPUT);
  pinMode(12, OUTPUT);
  pinMode(13, OUTPUT);
}

void loop()
{
  digitalWrite(13, HIGH);
  delay(1000);
  digitalWrite(13, LOW);
  digitalWrite(12, HIGH);
  delay(1000);
  digitalWrite(12, LOW);
  digitalWrite(11, HIGH);
  delay(1000);
  digitalWrite(11, LOW);
  digitalWrite(10, HIGH);
  delay(1000);
  digitalWrite(10, LOW);
  digitalWrite(9, HIGH);
  delay(1000);
  digitalWrite(9, LOW);
  digitalWrite(8, HIGH);
  delay(1000);
  digitalWrite(9, HIGH);
  digitalWrite(8, LOW);
  delay(1000);
  digitalWrite(9, LOW);
  digitalWrite(10, HIGH);
  delay(1000);
  digitalWrite(10, LOW);
  digitalWrite(11, HIGH);
  delay(1000);
  digitalWrite(11, LOW);
  digitalWrite(12, HIGH);
  delay(1000);
  digitalWrite(12, LOW);
}

Going Further:

1) Control the delay using a variable instead of a literal
2) Use an array to address output pins instead literal pin numbers
