Introduction: RFID Home Made Door Lock

RFID Door Lock device is a practical device that you can use during your daily life. When you scan your key card you can open the door lock .

I've modified the project from this website:

You will need

Arduino Uno (Or Other) –

Arduino Power Supply –

RC522 RFID Sensor

Breadboard & Jumpers for TestingMicro Servo –

2 x LEDs -

2 x 220Ω Resistors -

3D Printer & Filament (Optional for Lock) – This One UsedContainer or Housing For Sensor & Electronics

Step 1: Step1: Connect the Wire to Your Board.

Before we install other Module to your Arduino software ; first, you need to connect the wire to your board.

Here is the picture.

The LCD sensor and the battery isn't required if you don't need. If you are going to connect your Arduino to your computer, you won't need the battery. TheLCD panel s

You will probably need a 3D printor to print the door lock

The 3D Print Files is already uploaded.

Step 2: Step 2: Coding and Combine

First , you will need to download the RFID master file so your Arduino could recognize the words in the RFID module.

Download the RFID master file :

Here is the code, just copy the code and paste it in the Arduino software.

Download the Code:

After you've download the RFID master file, you will need to insert it to the Arduino File.

You will have to read the code of your key card. Scan your key card:

You can use iron wires to combine your device

Step 3: Step 3: Congratulations!!!! It's Done!!!!!


The Final project should look like this:

Step 4:
