This page explains how to build an RFID reader with just an Arduino (Nano 3.0 was used in testing, but other models may be compatible), a wire coil made by hand, and various affordable common components. Credits The hardware and software designs for this project are based in part on the ideas, code and schematics
Intro: RFID Cat Door Only the pet with the correct RFID tag can unlock this specific cat door/flap. Arduino is responsible for overseeing the process. It features a custom antenna large enough to function as a gate, enabling the animal to easily and consistently activate it. Some methods and techniques are borrowed from my previous
In this tutorial you can make an RFID access system. It’s very simple and can be used with a wide variety of end-uses. Updated 18/03/2013 The purpose of this project is to prototype a basic RFID access system. Although it is not that complicated, this article is my response to a kit reviewed in the Australian “Silicon
RFID tags are all over the place. They’re used in building access control systems, passports, inventory tracking . . . This instructable will show how you can use an Arduino and a few simple components (wire coil, transistor, capacitor, resistor) to make a device that can spoof an 125 KHz (low frequency) RFID tag.
Dear friends welcome to another Instructable. This is Nick from educ8s.tv and today we are going to learn how to use this RFID Reader with Arduino in order to build a simple lock system. For the first time, we are going to use RFID tags with Arduino. I have built a simple project which reads
RFID is a non-contact, automatic identification technology that uses radio signals to identify, track, sort and detect a variety of objects including people, vehicles, goods and assets without the need for direct contact or line-of-sight contact (as found necessary in bar code technology). RFID technology can track movement of objects through a network of radio-enabled
Surya Mattu is a creative technologist who loves to make things. He’s based in NYC and working at ITP, a two-year graduate program exploring the imaginative use of communications technologies. Today he’s sharing with us how feasible it could be to build an RFID-controlled entry for students using Arduino Yún. Read other guest posts on Arduino Yún.
I just received my RC522 RFID reader and made this simple Arduino access control system that uses the reader, a buzzer for the alarm and a relay shield for the security system. The relay can be used to open a door lock and if you need a louder alarm then you can replace the small

If you ever wanted to integrate RFID functionality into your project, this small tutorial might help you accomplish that. I used the RDM630 module from seeedstudio in its UART version. It comes on a small board with presoldered connectors which fits perfectly on a breadboard. You only need to connect the antenna to the two pin socket.
