Hallo Leute, ich brauche deine Hilfe bei meinem Projekt. Ich habe eine 2 Textfelder (Typ String) in einem C# -Programm und ich muss diese Zahlen an Arduino mit einem Serial.Port senden. Bis jetzt habe ich einen der Werte zu arduino geschickt, aber es funktioniert nicht sehr gut, wenn ich "1200" arduino Lese und zeige: 1,2,0,0 ich brauche "1200". Wie sende ich 2 Werte von C# zu Arduino? Wie das Arduino diese Werte (x und y) lesen wird?Von C# zu Arduino mit Serial.Port
