Start mit Arduino?

[ahave]

Hallo Rabenauge,
Es klappt immer noch nicht. Beim hochgebocktem Chassis schon, sobald das Ding auf dem Boden steht, fährt es vor und zurück, Er zuckt nur mal kurz nach links. Drehen auf der Stelle geht einfach nicht. Auch die Räder lassen sich leicht festhalten, wenn die Motoren drehen. Könntest Du Dir bitte die dreh-Funktion anschauen? Evtl. ohne der Rampe? Länger drehen?


Hier noch ein paar daten...

Du wolltest eine stromlaufplan des Chassis:



die zusätzlichen Verbindungen sehen so aus:

von dem Code habe ich schon einighes verstanden, weiss aber echt nicht was ich noch probieren könnte...
