This is a really easy rfid door lock mechanism which is based on the arduino uno and the rc522 rfid sensor which allows you to use rfid tags or cards to lock and unlock a door drawer or cupboard.

Rfid door lock using arduino uno.

For example only the person with the right informat. Here we will make a smart rfid door lock by using arduino and ultrasonic sensor. Easy user interface just one rfid tag needed whether delete or add tags to memory. The aim is to control a door lock without keys but using a smart phone instead.

Rst digital pin 9. Rst pin goes to digital pin 9. So we can use an rfid system to open a door. You can load as many rfid tags as you d like onto the arduino and add or remove tags to provide more or fewer people with access.

Miso digital pin 12. Unlocks a door controls a relay actually using a rc522 rfid reader with spi interface on your arduino. In this tutorial we will learn how to use the rfid mfrc522. Arduino codes and library.

Hey friends in this video i will show you how to make rfid lock system visit my website to download codes and circuit diagrams https www viralsciencecrea. Rfid and keypad door lock and alert system using arduino. This is a simple project made with arduino uno r3. Hence number on the card is 0001080589 code and explanation.

In the below code the rfid tag number are stored in the char tag. So we are going to use the hardware spi pins of the arduino uno. The complete rfid door lock arduino code is given at the end of this project. Mosi digital pin 11.

Sck digital pin 13. 62 is xor value for 02 xor 00 xor 10 xor 7d xor 0d. The rfid reader module uses the spi interface in order to communicate with arduino. I hope you guys enjoy learning this project.

The 4x4 keypad has 8. 180088f889e1 is my rfid tag number stored in the microchip of the transponder the length of the tag number is 12 we have defined. To open the door the user will have to first scan the right tag and then he will have to enter the correct password. Smart bt door lock simple arduino project showcase by arun.

You define a master card which acts as a programmer then you can able to choose card holders who can able to unlock the door or not. Next connect the keypad with arduino. Rfid reader arduino. The rfid lock box combines arduino rfid and a solenoid to make your very own personal safe.

Sda digital pin 10.
