Example sketch/program showing An Arduino Door Access Control featuring RFID, EEPROM, Relay
--------------------------------------------------------------------------------------------------------------------
This is a MFRC522 library example; for further details and other examples see: https://github.com/miguelbalboa/rfid

Use a Master Card which is act as Programmer then you can able to choose card holders who will granted access or not
* **Easy User Interface**
Just one RFID tag needed whether Delete or Add Tags. You can choose to use Leds for output or Serial LCD module to inform users.
* **Stores Information on EEPROM**
Information stored on non volatile Arduino's EEPROM memory to preserve Users' tag and Master Card. No Information lost
if power lost. EEPROM has unlimited Read cycle but roughly 100,000 limited Write cycle.
* **Security**
To keep it simple we are going to use Tag's Unique IDs. It's simple and not hacker proof.

For visualizing whats going on hardware we need some leds and to control door lock a relay and a wipe button

to use common cathode led or just seperate leds, simply comment out #define COMMON_ANODE,
