BMW e36 Tacho sketch

Arduino Code für GameDash (XSimulator Motion Simulator)

unten stehender Code ist aus bestehenden Sketche adaptiert und verändert
(Technikprojekte, XSIMULATOR)

Alle funktionen des Tacho,  Ganganzeige, eine 8 stellige konfigurierbare LED-Anzeige für Rpm

funktioniert mit Mega2560, Uno und Nano

Die Pins müssen den entsprechenden Mikrocontroller angepasst werden.
