Dieses Beispiel erzeugt ein Lauflicht, bestehend aus 8 LEDs. Die Funktionsweise wird in dem Quelltext ausreichend erklärt. Experimentiert ein wenig mit der Reihenfolge oder den delay() Befehlen, um unterschiedliche Muster zu erzeugen.
In folgenden Kapiteln werden wir viele weitere Möglichkeiten kennenlernen, die LEDs in verschiedenen Mustern blinken zu lassen.
