7-segment display

[Gij Kieken Profiel]

Ik heb een stukje rechtuit rechtaan code geschreven voor de bediening van een groot zeven segment display.(Arduino UnoR3 of Nano)
Met een 10-positie draaischakelaar selecteer je het gewenst nummer van 0 tot 9 (telkens slechts 1 positie mogelijk).
Ik heb er een Error melding (<-> teken) in gestoken ingeval van kabelbreuk.
Hoe zou ik eventueel dezelfde Error melding kunnen geven ingeval er toch (door welke reden dan ook) twee ingangen bediend zijn?
Bijgevoegd mijn voorlopige code.
Alle tips zijn welkom.
