I have been through numerous websites that all repetitively explain the same example over and over for this type of project (basically verbatim), but what I would like to do is a little different and much simpler.
Wanted- simple access granted by showing the right card to the reader. No serial monitors, no computer, no screens. I need to read the UID and compare it to the two cards that I have. I used the Dump example to find the UID’s of both of my cards.
Currently- Code for the project is attached. I have a simple “readDigital” stuck in the “KeycardCheck” function at the moment to take the place of the commands I am looking for.
The help I need- need someone to do a quick walk through of a quick and easy way to grab the uid, compare to the two I have, and set a flag value of “accepted” or “denied”.
Thanks for any help
