Änderungen gegenüber dem letzten Mal

Im vorherigen Programm wurde die Verzögerungszeit auf 500 Millisekunden eingestellt. Bei der Messung des Werts des Beschleunigungssensors wurde diese jedoch verbessert, sodass die Verzögerung selbst angepasst werden kann, um die Verzögerungszeit bei der Bewegungserkennung zu verkürzen. ..
