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 . If you wire up a RC522 to a 5V processor you need level shifters to protect the .

If you wire up a RC522 to a 5V processor you need level shifters to protect the chip from the output signals from the 5V chip. Despite many on line tutorials showing nothing in the way of level shifting it is needed to avoid damaging the RFID reader. It can be done simply with a bunch of resistors.

The RC522 works fine for a while, so should be no wiring problems, but after a few minutes it just starts either. sending an identical gliched readout from any RFID card; stops reading or sending RFID data completely; After I close and open the COM port window, it works fine for a few minutes again.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.I was attempting to make an RFID system for a long time now, and I consistently ran into one problem: The reader would not ever read a card. I even tried the built-in self-test function and it passed (See Attachments).
Arduino is Nano (Old Bootloader) and RFID reader is RC522. Magnetic Hall sensor is just a normal sensor with a magnet mounted on door beneath it so it knows when the door is opened/closed. The whole idea is this: When door open - lights up and stay up for 6 more seconds after closing the door. I am working with RFID-RC522 and Arduino UNO. I have check pin configurations again and again tried different libraries. It is not reading card and red led on RC522 is consistently on. The RC522 RFID module is a popular choice for such projects due to its ease of use and compatibility with the Arduino platform. Paired with an I2C LCD display, this system can provide real-time feedback to the user. You can read more about the RC522 RFID module in this article: How to Use RFID RC522 with Arduino: A Complete Beginner's Guide Some of the RC-522 RFID card reader modules that can be bought on ebay / aliexpress have a problem: they do not read all (types of) cards they should be able to read. In this blog post I want to explain how to recognize these faulty readers and how to fix them.
