* MFRC522 - Library to use ARDUINO RFID MODULE KIT 13.56 MHZ WITH TAGS SPI W AND R BY COOQROBOT. * ----------------------------------------------------------------------------
* The library file MFRC522.h has a wealth of useful info. Please read it. * This is a MFRC522 library example; see https://github.com/miguelbalboa/rfid
* The functions are documented in MFRC522.cpp. * for further details and other examples.
*
* NOTE: The library file MFRC522.h has a lot of useful info. Please read it.
* *
* Based on code Dr.Leong ( WWW.B2CQSHOP.COM )
* Created by Miguel Balboa (circuitito.com), Jan, 2012.
* Rewritten by Søren Thing Andersen (access.thing.dk), fall of 2013 (Translation to English, refactored, comments, anti collision, cascade levels.)
* Released into the public domain. * Released into the public domain.

* Example sketch/program showing how to read data from a PICC (that is: a RFID
* Tag or Card) using a MFRC522 based RFID Reader on the Arduino SPI interface.
* *
* Sample program showing how to read data from a PICC using a MFRC522 reader on the Arduino SPI interface. * When the Arduino and the MFRC522 module are connected (see the pin layout
*----------------------------------------------------------------------------- empty_skull * below), load this sketch into Arduino IDE then verify/compile and upload it.
* Aggiunti pin per arduino Mega * To see the output: use Tools, Serial Monitor of the IDE (hit Ctrl+Shft+M).
* add pin configuration for arduino mega * When you present a PICC (that is: a RFID Tag or Card) at reading distance
* http://mac86project.altervista.org/ * of the MFRC522 Reader/PCD, the output will show the ID, type and any data
----------------------------------------------------------------------------- Nicola Coppola * blocks it can read. Note that you may see some "Timeout in communication"
* Pin layout should be as follows: * messages when removing the PICC from reading distance to early.
* Signal Pin Pin Pin *
* Arduino Uno Arduino Mega MFRC522 board * If your reader supports it, this sketch/program will read all the PICCs
* presented (that is: multiple tag reading). So if you stack* two or more
* PICCs on top of each other and present them to the reader, it will first
* output all details of the first and then the next PICC. Note that this
* may take some time as all data blocks are dumped, so keep the PICCs at
* reading distance until complete.
*
* Typical pin layout used:
* ------------------------------------------------------------ * ------------------------------------------------------------
* Reset 9 5 RST * MFRC522 Arduino Arduino Arduino
* SPI SS 10 53 SDA * Reader/PCD Uno Mega Nano v3
* SPI MOSI 11 51 MOSI * Signal Pin Pin Pin Pin
* SPI MISO 12 50 MISO * ------------------------------------------------------------
* SPI SCK 13 52 SCK * RST/Reset RST 9 5 D9
* * SPI SS SDA 10 53 D10
* The reader can be found on eBay for around 5 dollars. Search for "mf-rc522" on ebay.com. * SPI MOSI MOSI 11 51 D11
* SPI MISO MISO 12 50 D12
* SPI SCK SCK 13 52 D13
