RC522读卡历程基于Arduino

/*
* --------------------------------------------------------------------------------------------------------------------
* Example to change UID of changeable MIFARE card.
* --------------------------------------------------------------------------------------------------------------------
* This is a MFRC522 library example; for further details and other examples see: [url]https://github.com/miguelbalboa/rfid[/url]
*
* This sample shows how to set the UID on a UID changeable MIFARE card.
* NOTE: for more informations read the README.rst
