RFID door lock access control system | How to make an RFID door lock system using Arduino
Hello, friends in this post I'll show you How to make RFID based door lock system using Arduino Uno RC522 RFID module in a simple way. To make this project I used Arduino Uno as a microcontroller. I have 2 RFID cards & 1 RFID tag/Keychain. The LCD display is used to show instructions to the user. I used a 12V solenoid lock to unlock the door.
I make a detailed article on my website, you can visit my website for complete details of this project.

I already make a complete tutorial video on this project so you can also refer to my YouTube channel for more interesting projects.
Copy the following code and upload it to the Arduino
For Complete Article visit my WEBSITE for more details.
In this project, we will be using an Arduino board to control an RFID door lock. The lock will be activated when the correct RFID tag is presented to the reader, and will remain locked until the tag is removed.

RFID stands for Radio Frequency Identification and is a contactless technology widely used in many industries for personnel tracking, access control, supply chain management, library book tracking, toll systems, etc.
An RFID reader is a device used to gather information from an RFID tag, which is used to track individual objects. Radio waves are used to send data from the tag to a reader.
How RFID works?
An RFID system consists of two main components: a transponder or tag located on the object we want to identify and a transceiver or reader.
The RFID reader consists of a radio frequency module, a control unit and an antenna coil that generates a high-frequency electromagnetic field. On the other hand, the tag is usually a passive component, consisting only of an antenna and an electronic microchip, so when it comes close to the electromagnetic field of the transceiver, due to induction, a voltage is generated in its antenna coil and This Voltage serves as power for the microchip
Specifications
Input voltage: 3.3v
Frequency: 13.56MHz
That's all guys let's get into the Connections & Coding part.
RFID With Arduino
So that's the basic working principle and now let's see how we can use RFID with Arduino and build our own RFID door lock. We will be using tags based on the MIFARE protocol and the MFRC522 RFID reader, which cost only a couple of dollars.
These tags have 1kb of memory and have a microchip that can perform arithmetic operations. Its operating frequency is 13.56 MHz and the operating distance is up to 10 cm depending on the geometry of the antenna. If we bring one of these labels closer to a light source, we can see the antenna and microchip we discussed earlier.
The RFID reader module uses the SPI protocol for communication with the Arduino board and this is how we must connect them. Note that we need to connect the VCC of the module to 3.3V and as for the other pins we don't have to worry as they are 5V tolerant.
