+* zuerst verbinden wir ein Beinchen des Lichsensors mit dem 5V-Anschluss des Arduino
+* An das zweite Beinchen schließen wir einen 10k-Ohm Widerstand an
+* Das zweite Beinchen des 10k-Ohm Widerstands verbinden wir mit GND auf dem Arduino
+* Da, wo sich der Lichtsensor und das 10k-Ohm Widerstand "berühren" stecken wir noch ein Kabel zum Eingang A0 des Arduino
 
 So muss da aussehen, wenn wir fertig sind:
