rfid tag red light 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. Here's a picture of the card reader I have. If yours looks identical, then this library should work: https://github.com/ljos/MFRC522. If you do not know your phone's NFC reader location, try looking up the phone's manual on the manufacturer website, and/or search online for something like "iPhone 7 NFC antenna location". Depending on your phone, you may need to use an unusual orientation/rotation of your YubiKey.

Here's a picture of the card reader I have. If yours looks identical, then this library should work: https://github.com/ljos/MFRC522. Now, when you place the RFID tag that gave you access on the RFID module, then the green LED will glow and displays “Authorized Access” on the Serial Monitor. When you place other RFID tags, the red LED will glow and displays “Access Denied” on the Serial Monitor. In this tutorial, you will build a device that uses RFID detection to turn on an LED light. This project provides an introduction to using RFID sensors to control responses with an Arduino. I have put together a sketch where I use two RFID readers, an RTC module and three leds to simulate locks. Sketch is working fine, and all looks ok. The RC522 RFID reader has an on-board led that is ligting up red when powered.
This blog post shows how to use the MFRC522 RFID reader. I'll do a quick overview of the specifications and demonstrate a project example using an Arduino.RFID Tag/card Verification System : Arduino UNO + RFID RC522 + LCD 16x2 I2C + LEDs: In this project, the RC522 RFID (Radio Frequency IDentification) module was tested, if the correct badge (or card) that was scanned, "valid badge" will be displayed on the LCD screen and the green LED will light up for a few seconds , if not, "..
Hi all, I am newbe for Raspberry PI & Arduino. I have been tested RFID-RC522 on the Arduino with the simple DumpInfo code. I have a red solid light on the RFID-RC522 and on the COM3. PIN OUT. I have a RFID RC522 board that was working perfectly, until by mistake I tried to write it with a phone as if it was a RFID tag and now it stopped working, in the way that its led still turns on but it's not recognised by the code (it says firmware version 0x0). A visual indication of the state of the RFID Card Reader is given with the on-board LED. When the module is successfully powered-up and is in an idle state, the LED will be GREEN. When the module is in an active state searching for or communicating with a valid tag, the LED will be RED. Im trying to make a security system with RFID and LED. It is actually really simple but im not sure how should i change my Code. I have already a code that works. I can light the greed led up, if i use the right card. If i use the second card the red goes on. But i .

NFC Tag Reader. To retrieve information from an NFC tag, a user is required to use an NFC tag reader. Unlike RFID, where specialized RFID readers are used (like on a store’s front door to keep check of the store’s inventory), a user may not require a dedicated NFC tag reader, his smartphone or smartwatch may be enough.
