Ich hoffe, so ist es richtig mit dem Code....
@postmaster-ino
eigentlich lasse ich mir die Fehler schon anzeigen. Hat mir schon des öfteren geholfen, ein vergessenes Semikolon oder eine vergessene Klammer zu setzen. Bei diesem Sketch hat der Compiler nicht gemeckert. Da dachte ich .... nun gut, dann mal hoch auf den Uno damit.
Wie schon erwähnt, funktioniert soweit alles bis auf das Stoppen des Motors

. Vorerst denke ich mir, lieber ein häßliches Auto als zu Fuß gehen....
