Hallo Welt!
Ich hab da so ein kleines Projekt am laufen und könnte Hilfe gebrauchen, weil ich mich ein wenig verzettelt habe, was die Übertragung von Seriell über Midi zum USB angeht.
Das Setup liegt bereits auf Midi_Controller DIY
Der Code:
//*****************************************************************************
//Sketch from Peter Kussike 2016 for
//3 Poti 100k, 3 Momentary Switches, 1 Ultrasonic Sensor HC SR04 and an Arduino Nano.
//I took a Nano because it's so small and has the same funktions as his big brother UNO.
//In the Box it is Connected via MiditoUSB connector while midi.h did not work out well.
//This is Sketch Nr.1 vom 12.11.2016
//Published under Midi_Controller DIY
//its open source and free for all and everyone off course!
