Servus Leute,
ich hab mir im Internet mal eine Anleitung für eine sagen wir.. Teeuhr gesucht und sie auf meine Hardware angepasst, soweit funktoniert der Code.
Jetzt möchte ich den noch erweitern,
-Den Timer würde ich gerne über das Keypad einstellen und nicht fest im Code.
-Dann würde ich gerne noch eine Widerstandsmessbrücke mit reinprogrammieren (siehe Bild)
(Erst wenn Code eingegeben und die vier Widerstände richtig eingesteckt sind wird die Teeuhr gestoppt)
-wenn im spiel die Widerstände oder der Code falsch eingesetzt werden könnte man da den Timer beschleunigen oder einfach ein paar minuten abziehen?
wie könnte ich das am besten machen.
Danke
Sepp
ps. bitte keine belehrungen.. das ist für ein Spiel und nur für ein Spiel..ausserdem sprechen wir ja von einer Teeuhr... die halt nur sehr kompliziert zu bedienen ist
