Moin Miteinander
Ich bin gerade dabei ein RFID Zugangskontrolle zu Programmieren.
Der bereich mit RFID Karte auslesen und die Daten an den Server Schicken
sowie die Prüfung klappt so weit.
Mein Problem aktuell ist
ich möchte noch 2 Taster bzw Input Signal in das Programm einbinden.
Nach langen probieren hab ich raus gefunden das der void loop teil
nur aktiv bzw aktiviert wird wenn eine karte ausgelesen wird.
Aber warum ist das so ? bzw wie kann ich das ändern
hab schon das Internet durchsucht ob jemand das gleiche Problem hat wie ich.
Würde mich sehr freuen wenn mir jemand bei meinen Problem helfen kann
MfG
Stefan
