Ich habe so etwas schon mit einer Tastatur 4*3 0-9A-F gemacht.
Das Programm steuerte zwei Garagentore die ich mit der Tastaur aufgemacht habe (jeweils ein Passwort für ein Tor).
Funktion:
-Eingabe das Passwortes öffente da entsprechende Tor)
-nur bestätigung der Eingabe egal ob falsch oder richtig durch die LED.
-Timeout nach einer bestimmten Zeit wird da Speicher array gelöscht.
-Funktion zum vergleichen des Speicher Arrays mit dem Passwortarray
