-------------------------------------------------------------------------------------------------------------------- * Initial Author: ryand1011 (https://github.com/ryand1011)
Example sketch/program showing how to read data from a PICC to serial. *
-------------------------------------------------------------------------------------------------------------------- * Reads data written by a program such as "rfid_write_personal_data.ino"
This is a MFRC522 library example; for further details and other examples see: https://github.com/miguelbalboa/rfid *
* See: https://github.com/miguelbalboa/rfid/tree/master/examples/rfid_write_personal_data
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. * Uses MIFARE RFID card using RFID-RC522 reader
* Uses MFRC522 - Library
When the Arduino and the MFRC522 module are connected (see the pin layout below), load this sketch into Arduino IDE * -----------------------------------------------------------------------------------------
then verify/compile and upload it. To see the output: use Tools, Serial Monitor of the IDE (hit Ctrl+Shft+M). When * MFRC522 Arduino Arduino Arduino Arduino Arduino
you present a PICC (that is: a RFID Tag or Card) at reading distance of the MFRC522 Reader/PCD, the serial output * Reader/PCD Uno/101 Mega Nano v3 Leonardo/Micro Pro Micro
will show the ID/UID, type and any data blocks it can read. Note: you may see "Timeout in communication" messages * Signal Pin Pin Pin Pin Pin Pin
when removing the PICC from reading distance too early. * -----------------------------------------------------------------------------------------
