i'm working on a project for using the proximity card reader with arduino uno, the signal of card reader is wiegand, actually this my first time to work with wiegand and i need some help.
the application that i work on is to make the uno read multiple cards on the same card reader and detect the serial no. of each card and enable/disable a relay output.
Card A will enable relay A. Card B will enable relay B. ... and so on.
i think the trick of my code is detecting the different card cods and work accordingly, is that possible ??
