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. 22 | * 23 | * Typical pin layout used: 24 | * ----------------------------------------------------------------------------------------- 25 | * MFRC522 Arduino Arduino Arduino Arduino Arduino 26 | * Reader/PCD Uno Mega Nano v3 Leonardo/Micro Pro Micro 27 | * Signal Pin Pin Pin Pin Pin Pin 28 | * ----------------------------------------------------------------------------------------- 29 | * RST/Reset RST 9 5 D9 RESET/ICSP-5 RST 30 | * SPI SS SDA(SS) 10 53 D10 10 10 31 | * SPI MOSI MOSI 11 / ICSP-4 51 D11 ICSP-4 16 32 | * SPI MISO MISO 12 / ICSP-1 50 D12 ICSP-1 14 33 | * SPI SCK SCK 13 / ICSP-3 52 D13 ICSP-3 15 34 | */ 35 | 36 | #include 37 | #include 38 | 39 | #define RST_PIN 9 // Configurable, see typical pin layout above 40 | #define SS_PIN 10 // Configurable, see typical pin layout above 41 | 42 | MFRC522 mfrc522(SS_PIN, RST_PIN); // Create MFRC522 instance 43 | 44 | void setup() { 45 | Serial.begin(9600); // Initialize serial communications with the PC 46 | while (!Serial); // Do nothing if no serial port is opened (added for Arduinos based on ATMEGA32U4) 47 | SPI.begin(); // Init SPI bus 48 | mfrc522.PCD_Init(); // Init MFRC522 49 | mfrc522.PCD_DumpVersionToSerial(); // Show details of PCD - MFRC522 Card Reader details 50 | Serial.println(F("Scan PICC to see UID, SAK, type, and data blocks...")); 51 | } 52 | 53 | void loop() { 54 | // Look for new cards 55 | if ( ! mfrc522.PICC_IsNewCardPresent()) { 56 | return; 57 | } 58 | 59 | // Select one of the cards 60 | if ( ! mfrc522.PICC_ReadCardSerial()) { 61 | return; 62 | } 63 | 64 | // Dump debug info about the card; PICC_HaltA() is automatically called 65 | mfrc522.PICC_DumpToSerial(&(mfrc522.uid)); 66 | } 67 | -------------------------------------------------------------------------------- /README.md: -------------------------------------------------------------------------------- 1 | # RFID 2 | Download the librarby.
