/* IDEEN:
1. Erweitere das Programm: sobald ein Objekt "zu nahe" am Sensor ist, soll
die eingebaute LED aufleuchten.
2. Zwischen welchen Werten liegt der gemessene Wert? Erweitere das Programm
so, dass der Wert in den Bereich [0,100] umgerechnet wird.
3*. Bestimme eine Formel, die den gemessenen Wert in die Distanz (in mm)
umrechnet.
