Hallo, habe Probleme bei calibration von IR-Sensor bei Zeus Car. Ein Sensor zeigt immer `Ein´ der andere immer ´Aus´. Einstellen mit Potentiometer funktioniert gar nicht. Kalibration mache ich mit Programm 9\_hc165\_and\_ir\_obstacle. Eingeschlossen sind die Fühler richtig. Wie soll ich weiter vorgehen. Tom
