The problem is that you don't tell your Arduino which bytes you want to read, do it like this. UID[i] = mfrc522.uid.uidByte[i]; Get rid of the UID1 and do this and add this in the same for loop.I connected a RFID-reader with Arduino Nano, so I can read the Cards UID with the Serial M.
if(mfrc522.PICC_IsNewCardPresent()) { unsigned long uid = getID(); if(uid !== 0){ Serial.print("Card detected, UID: "); Serial.println(uid); } } Based on the answer by Thomas . Learn how to extract the unique identification (UID) from RFID tags using Arduino! In this step-by-step tutorial, we’ll explore the MFRC522 RFID module, demo. An RFID system uses: tags attached to the object to be identified, in this example we have a keychain and an electromagnetic card. Each tag has his own identification (UID). .RC522 RFID/NFC reader (also called RFID-RC522 Module) can: Read the UID of RFID/NFC tag. Change the UID of RFID/NFC tag (only if the tag is UID-writable) Write data to RFID/NFC tag. .
In this guide, we'll explore how to use the MFRC522 RFID module with an Arduino. By the end of this article, you'll be able to create a simple RFID reader system and understand how RFID technology works.You’ve unlocked the secrets of UID & Learned How to Read RFID Tags, the Unique Identifier, and learned how to make Arduino read it from RFID tags. Armed with this knowledge, you can . I connected a RFID-reader with Arduino Nano, so I can read the Cards UID with the Serial Monitor. My code: MFRC522 mfrc522 (SS_PIN, RST_PIN); // Create MFRC522 .
Hello guys, in this tutorial you will learn how to get the number of your RFID (Radio Frequency IDentification) tag or card using the RFID reader RC522. This number is called UID (Unique . The problem is that you don't tell your Arduino which bytes you want to read, do it like this. UID[i] = mfrc522.uid.uidByte[i]; Get rid of the UID1 and do this and add this in the same for loop. if(mfrc522.PICC_IsNewCardPresent()) { unsigned long uid = getID(); if(uid !== 0){ Serial.print("Card detected, UID: "); Serial.println(uid); } } Based on the answer by Thomas Matthews in a similar discussion .

In this post we will go over how to use the RC522 RFID Module with Arduino. We’ll focus on basics, module pins, how to connect to Arduino, programming in Arduino IDE, and testing. The main focus will be around reading an RFID tag’s UID (Unique ID).Learn how to extract the unique identification (UID) from RFID tags using Arduino! In this step-by-step tutorial, we’ll explore the MFRC522 RFID module, demo.
An RFID system uses: tags attached to the object to be identified, in this example we have a keychain and an electromagnetic card. Each tag has his own identification (UID). two-way radio transmitter-receiver, the reader, that send a signal to the tag and read its response.
RC522 RFID/NFC reader (also called RFID-RC522 Module) can: Read the UID of RFID/NFC tag. Change the UID of RFID/NFC tag (only if the tag is UID-writable) Write data to RFID/NFC tag. Read data from RFID/NFC tag. In above capabilities, for Arduino, reading the UID is .
