/*
	Als erstes wird der Bob3 Pseudo-Gebootet:
    Die Augen beginnen Weisz zu leuchten.
    Danach werden die Augen beim PC angeschlossen PURPLE leuchten,
    sonst BLUE.
    Das bedeutet das man nun in der loop-Funktion ist und
    man sich entscheiden kann:
    drueckt man den linken Arm(1), sendet
    der Bob3 mittels Morsecodes das Wort
    "Hello World". Drueckt man den rechten Arm(2)
    sendet er das Wort "SOS".
    Nach jeden Uebertragenen Buchstaben, wechselt die
    Augenfarb von Orange auf OFF und andersum.
    Am Ende sind beide Augen fuer eine Weile Gruen.
    Danach kann man sich wieder entscheiden.
