Security Access Using RFID Reader - Arduino Project Hub

About this project

What is an RFID reader?

RFID tagging is an ID system that uses small radio frequency identification devices for identification and tracking purposes. An RFID tagging system includes the tag itself, a read/write device, and a host system application for data collection, processing, and transmission.

In simple words an RFID uses electromagnetic fields to transfer data over short distances. RFID is useful to identify people, to make transactions, etc...

You can use an RFID system to open a door. For example, only the person with...

Arduino Ethernet Rfid card reader - Arduino Project Hub

About this project

Have you ever thought of adding an RFID tags/card security system or monitoring system in your home and/or office. Well if you got here i bet you already looked up how freaken expensive they are ranging from $200 to $2000, TOO MUCH RIGHT!?? Well a friend and I have decided to make a system that would cost under $100 and could do even more than just access a door, so this...

Arduino Ethernet Rfid card reader - Arduino Project Hub

A internet enabled arduino rfid tag reader. that for $20 more can open doors. This system was designed to track students at our highschool and we hope the school approves it.

Here is the prototype:

You might be thinking it might take a long time, yatta yatta yatta. Yet this thing only took me about 6 hours (Because I had power issues), but this could take you about 30 minutes to setup like the...

Interface RFID Shield With Arduino - Arduino Project Hub

RFID Reader

Arduino RFID Reader Code

This RFID kit comes pre assembled so all you will need to do is plug your Arduino in it and you will be good to go.

This RFID works on UART protocol so to read the RFID tag we will need to read the UART data. In this sample code we will read the RFID tag and will display it on the serial monitor.

int count = 0; // count...

RFID Door Unlock - Arduino Project Hub

Here is a diagram of the wiring.

Setting up the Arduino MKR1000

We will load StandardFirmataWifi ( https://github.com/firmata/arduino ) on the Arduino. We then need to make some changes to wifiConfig.h, Make sure Option A is not enabled. We want to use Option B for WIFI_101. Enter in your SSID and password.

Now under the main page scroll down and uncomment SERIAL_DEBUG, we need to get the...

RFID Door Lock with Arduino - Arduino Project Hub

Panel Mount Dual Power Cable

Wire Nut, Electrical Tape, Solder, or other wire connection method.

Note that using a straight door latch solenoid requires power to unlock the door. If you lose power, you will be effectively locked out and unable to open your door until power is returned to the system. With the electronic strike plate, you can still use your regular key to open the door in the case...

Security Access Using RFID Reader - Arduino Project Hub

Reading data from an RFID tag

After having the circuit ready, go to File > Examples > MFRC522 > DumpInfo and upload the code. This code will be available in Arduino IDE (after installing the RFID library).

Then, open the serial monitor. You should see something like the figure below:

Approximate the RFID card or the keychain to the reader....
