BMW e36 Tacho sketch

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.
