Adafruit PN532 RFID/NFC HELP
I have recently got my hands on the Adafruit PN532 board and I'm having a blast playing with it!
I have looked through the sketches and played around with them as much as I'm comfortable doing.
What i really need is a sketch that will let me add cards/remove cards from an internal database, and when a card that's in the database is presented i need a logic high sent to a pin that i can use for something else!
Kind of like a security entry system.
If anyone could help out, that would be great!
