Hallo,
ich habe nach einer Anleitung bei Youtube versucht eine Menüführung mit dem LCD Keypad Shield zu realisieren.
http://eeenthusiast.com/arduino-lcd-tutorial-display-menu-system-scrolling-menu-changeable-variables-projects/
Leider verwendet der Ersteller der Anleitung das Shield nicht sondern normale Buttons.
Jetzt würde ich gerne das Menü über die Buttons des Shields steuern.
Irgendwie weiß ich nicht wie ich die Analogauswertung auf die const int input_Buttons[Number_of_Inputs] schreiben soll. Kann mir jemand helfen?
Danke
