Rfid Door Lock Using Arduino Uno
In this post you are going to learn about how to build an rfid and keypad based door lock using arduino.
Rfid door lock using arduino uno. 62 is xor value for 02 xor 00 xor 10 xor 7d xor 0d. Rst pin goes to digital pin 9. Sda digital pin 10. Hence number on the card is 0001080589 code and explanation.
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. 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. 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.
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. So we are going to use the hardware spi pins of the arduino uno. Rst digital pin 9. The complete rfid door lock arduino code is given at the end of this project.
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. The rfid reader module uses the spi interface in order to communicate with arduino. Arduino codes and library. 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.
This is a simple project made with arduino uno r3. In this tutorial we will learn how to use the rfid mfrc522. For example only the person with the right informat. Unlocks a door controls a relay actually using a rc522 rfid reader with spi interface on your arduino.
The aim is to control a door lock without keys but using a smart phone instead. Mosi digital pin 11. Here we will make a smart rfid door lock by using arduino and ultrasonic sensor. Rfid reader arduino.
Miso digital pin 12. 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 4x4 keypad has 8. In the below code the rfid tag number are stored in the char tag.
The i2c pins on arduino uno and arduino nano are a4 a5. The rfid lock box combines arduino rfid and a solenoid to make your very own personal safe. I hope you guys enjoy learning this project. Easy user interface just one rfid tag needed whether delete or add tags to memory.
