  2. * --------------------------------------------------------------------------------------------------------------------
  3. * Example sketch/program showing how to read data from a PICC to serial.
  4. * --------------------------------------------------------------------------------------------------------------------
  5. * This is a MFRC522 library example; for further details and other examples see: https://github.com/miguelbalboa/rfid
  6. *
  7. * Example sketch/program showing how to read data from a PICC (that is: a RFID Tag or Card) using a MFRC522 based RFID
  8. * Reader on the Arduino SPI interface.
  9. *
  10. * When the Arduino and the MFRC522 module are connected (see the pin layout below), load this sketch into Arduino IDE
  11. * then verify/compile and upload it. To see the output: use Tools, Serial Monitor of the IDE (hit Ctrl+Shft+M). When
  12. * you present a PICC (that is: a RFID Tag or Card) at reading distance of the MFRC522 Reader/PCD, the serial output
  13. * will show the ID/UID, type and any data blocks it can read. Note: you may see "Timeout in communication" messages
  14. * when removing the PICC from reading distance too early.
  15. *
  16. * If your reader supports it, this sketch/program will read all the PICCs presented (that is: multiple tag reading).
  17. * So if you stack two or more PICCs on top of each other and present them to the reader, it will first output all
  18. * details of the first and then the next PICC. Note that this may take some time as all data blocks are dumped, so
  19. * keep the PICCs at reading distance until complete.
  20. *
  21. * @license Released into the public domain.

  31. * SPI MOSI MOSI 11 / ICSP-4 51 D11 ICSP-4 16
