I have check pin configurations again and again tried different libraries. It is not reading card and red led on RC522 is consistently on.

Why is my RFID not working on my Arduino?

Step-3: Open the Arduino IDE and navigate to Sketch > Include the Library using “Add .ZIP Library…” option. Step-5: Inside Arduino IDE Navigate to File > Examples > AddicoreRFID. Select the “Addicore_RFID_Example” sketch and upload the sketch This issue is due to incorrect wiring or loose contacts to RFID sensor.

How to connect Arduino to mfrc522 module?

* * 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).

How can I see the output of my RFID reader?

To see the output: use Tools, Serial Monitor of the IDE (hit Ctrl+Shft+M). When * you present a PICC (that is: a RFID Tag or Card) at reading distance of the MFRC522 Reader/PCD, the serial output * will show the ID/UID, type and any data blocks it can read.

Why is my addicore RFID not working properly?

Select the “Addicore_RFID_Example” sketch and upload the sketch This issue is due to incorrect wiring or loose contacts to RFID sensor. You need to solder contact to get results.

How does a RFID tag work on an Arduino?

When * you present a PICC (that is: a RFID Tag or Card) at reading distance of the MFRC522 Reader/PCD, the serial output * will show the ID/UID, type and any data blocks it can read. Note: you may see “Timeout in communication” messages * when removing the PICC from reading distance too early.
