The RFID Door Lock System is constructed using 4 major components these are Arduino, RFID Redder Module, RFID Card or Key Fob Tag, IR Sensor, Servo Motor, and LCD Display. This system is also known as the card door lock system or key card door lock system. If you put the wrong card or key tag in front of the RFID door locks system box (RFID Reader) then the door would not unlock. In this system, you need a particular card or key tag and put it in front of the RFID door locks system box (RFID Reader) to unlock the door. So, see you in the next project or tutorial.In this project tutorial, we’ll learn how to make RFID based Electronic door locks systems using Arduino and RC522 RFID Module.

Now, save this script and click the run button.

Lcd.lcd_display_string('Door is open',2,2) Lcd.lcd_display_string('Door is locked',2,1) Lcd.lcd_display_string('Place your Tag',1,1) Lcd.lcd_display_string('Door lock system',1,0) Full details of this project - Download.Then, save this script and click the run button.

For that, copy and paste the following program on the Thonny IDE. Now let’s create the python script for this project. If you want to know whether I2C is working or not, run the following code on the terminal. Because the LCD screen and RFID module required these communication methods. OK, the RFID library is ready for this project.

sudo apt install python3-dev python3-pip.

At this point, the Raspberry Pi board must be connected to the Internet.

First, open the terminal and run the following commands one by one.

Ok, now let’s install the RFID library into Raspberry Pi OS. Then, connect the GPIO ribbon cable to the Raspberry Pi board and provide a power supply to the board. Now, connect the keyboard, mouse, monitor, ethernet cable, and SD card(OS installed) to the Raspberry Pi board. Also, connect the LCD and relay module to the extension board. And then, connect it to the extension board. Next, place the buzzer on the breadboard. Thirdly, connect the RFID module to the GPIO extension board. And then, connect the GPIO ribbon cable to the extension board. Secondly, connect the GPIO Extension board to the breadboard.
