Anhand
dieser klasse Anleitung hatte ich endlich Erfolg.
Ich konnte den Code der RFIDs auslesen.
Zuvor war ich mit Pidoorman und dem Raspberry leider gescheitert.
Die Codes wurden nicht erkannt.
Nun aber mit dem Arduino.
Schaltung:
D0 Wiegand an D2 Arduino (D0 am DK-2872 => Blau)
D1 Wiegand an D3 Arduino (D1 => Gelb)
GND Wiegand and GND Arduino (GND => Schwarz)
Software von der o.a. Webseite.
