Basierend auf #10: Pin 10 ist doppelt belegt.
JackKean:
Könntest Du das bitte etwas konkreter schreiben? Was meinst du damit, in Millis?
Leider ist delay blockierend, was bei mehreren quasi parallelen Abläufen vermieden werden muß. Daher nutzt man millis für Zeiten.
Ein Denkanstoß:

MicroBahner:
Oder Du versuchst es mal mit meiner MobaTools Lib.
Habe ich mir runtergeladen, werde ich ausprobieren
