Rfid Door Lock Using Arduino Uno

180088f889e1 is my rfid tag number stored in the microchip of the transponder the length of the tag number is 12 we have defined. The aim is to control a door lock without keys but using a smart phone instead. In this post you are going to learn about how to build an rfid and keypad based door lock using arduino.

Here we will make a smart rfid door lock by using arduino and ultrasonic sensor.

Rfid door lock using arduino uno.

In the below code the rfid tag number are stored in the char tag. Rst digital pin 9. 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. Unlocks a door controls a relay actually using a rc522 rfid reader with spi interface on your arduino.

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. 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. Miso digital pin 12. The rfid reader module uses the spi interface in order to communicate with arduino.

To open the door the user will have to first scan the right tag and then he will have to enter the correct password. Sck digital pin 13. This is a simple project made with arduino uno r3. Rfid reader arduino.

Sda digital pin 10. The i2c pins on arduino uno and arduino nano are a4 a5. So we can use an rfid system to open a door. Arduino codes and library.

62 is xor value for 02 xor 00 xor 10 xor 7d xor 0d. Rfid and keypad door lock and alert system using arduino. Mosi digital pin 11. Smart bt door lock simple arduino project showcase by arun.

So we are going to use the hardware spi pins of the arduino uno. In this tutorial we will learn how to use the rfid mfrc522. For example only the person with the right informat. The 4x4 keypad has 8.

Hence number on the card is 0001080589 code and explanation. I hope you guys enjoy learning this project. Next connect the keypad with arduino. Rst pin goes to digital pin 9.

Easy user interface just one rfid tag needed whether delete or add tags to memory. The rfid lock box combines arduino rfid and a solenoid to make your very own personal safe. The complete rfid door lock arduino code is given at the end of this project. Rfid rc522 and arduino uno pin configuration rfid rc522 arduino uno ss sda d10 sck d13 mosi d11 miso d12 irq not connected gnd gnd rst d9 3 3v 3 3v note.
