Ich hoffe hier kann mir geholfen werden.
Ich möchte bei meinem RC Car eine Melodie-Hupe hinzufügen. Das Ganze will ich mit einem DFPlayer mini, einen Arduino Nano und NRF24L01 anzusteuern.
Beim einschalten des Empfängers läuft die eingestellte (1. mp3-Datei) normal ab (setup).
Beim drücken des Button 1 am Sender beginnt die 1. mp3 kurz anzuspielen. Das geht 3 mal hintereinander und dann spielt es die Datei normal bis zum Ende ab.
Meine Vermutung nach liegt es daran, das der Tastendruck zu lang ist und somit die mp3 mehrmals hintereinander gestartet wird. Deshalb habe ich das ganze versucht mit einer for-Schleife zu stoppen. Brachte aber keinen Erfolg.
Hier mal der Code.
