Interfacing of rfid with arduino can be done by the following steps.
Rfid based door lock system using arduino uno.
Arduino uno or any other arduino.
If the wrong tag is scanned the door will stay closed and set off a buzzer.
The necessity of power supply for rfid readers varies from one product to another.
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.
The components you are going to require for rfid and keypad based door lock and alert system using arduino are as follows.
But here a 12v rfid reader is used for an.
So we are going to use the hardware spi pins of the arduino uno.
The goal is to open a door by using a specific tag that functions as an access badge.
There are many rfid readers are available in the market with 5v 9v and 12v.
4x4 keypad or 4x3 keypad.
This rfid door lock can be made easily at your home and you can install it in any door.
Intermediate protip 2 hours 25 722 things used in this project.
Rst pin goes to digital pin 9.
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.
When we see sophisticated door management system s the price tag struck immediately along with the utility of course.
Rfid door lock with arduino.
Arduino uno rfid based automatic door lock system using an arduino.
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.
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.
This project guide will detail the steps to create an rfid radio frequency identification door lock system using an arduino mega 2560.
In countries like india such automatic systems are not cheap by any yardstick.
In this case we will then use a relay so we can make it work too we are using the plunger as a lock so here is the connections for it.
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.
5v 2a power adapter.
Arduino rfid door lock hardware project setup.
