In the previous post you learned about rfid and keypad based door lock and alert system using arduino in which user had to scan the right tag and enter the right password to open the door lock and the system also sends us the confirmation message.
Rfid based door lock system using arduino uno.
So we decided to test a simple and cheap prototype to see if such a robust system could be developed using the tool of our choice arduino uno.
5v 2a power adapter.
The components you are going to require for rfid and keypad based door lock and alert system using arduino are as follows.
The goal is to open a door by using a specific tag that functions as an access badge.
Rfid door lock with arduino.
Interfacing of rfid with arduino can be done by the following steps.
Arduino uno rfid based automatic door lock system using an arduino.
But here a 12v rfid reader is used for an.
This rfid door lock can be made easily at your home and you can install it in any door.
So we are going to use the hardware spi pins of the arduino uno.
There are many rfid readers are available in the market with 5v 9v and 12v.
The rfid reader module uses the spi interface in order to communicate with arduino.
In countries like india such automatic systems are not cheap by any yardstick.
This project guide will detail the steps to create an rfid radio frequency identification door lock system using an arduino mega 2560.
You have seen rfid door lock mechanism in some hotels and other places where you don t need a key to unlock the room.
4x4 keypad or 4x3 keypad.
Rst pin goes to digital pin 9.
Arduino uno or any other arduino.
You are given a card and you just need to put it in front of a rfid reader box and the lock gets unlocked with a beep and a blink of led.
Intermediate protip 2 hours 25 722 things used in this project.
Irq pin stays unconnected.
As we are using a plunger it requires 9 volts to work and as we all know an arduino uno only has max 5 volts.
Rfid and keypad based door lock using 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.
When we see sophisticated door management system s the price tag struck immediately along with the utility of course.
If the wrong tag is scanned the door will stay closed and set off a buzzer.
