This rfid door lock can be made easily at your home and you can install it in any door.
Rfid door lock using arduino uno.
Rfid door lock with arduino.
If the wrong tag is scanned the door will stay closed and set off a buzzer.
An error occurred while retrieving sharing information.
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.
The goal is to open a door by using a specific tag that functions as an access badge.
The rfid reader module uses the spi interface in order to communicate with arduino.
Unlocks a door controls a relay actually using a rc522 rfid reader with spi interface on your arduino.
Easy user interface just one rfid tag needed whether delete or add tags to memory.
Miso pin goes to digital pin 12.
So we are going to use the hardware spi pins of the arduino uno.
Rfid and keypad based door lock using arduino.
In this post on arduino tutorial for beginners this topic about how to use module rfid rc522 with arduino uno r3.
Irq pin stays unconnected.
Next connect the keypad with arduino.
You have seen rfid door lock mechanism in some hotels and other places where you don t need a key to unlock the room.
Smart bt door lock simple arduino project showcase by arun.
With this simple tutorial we can apply this application to control the huge things in our life.
The i2c pins on arduino uno and arduino nano are a4 a5.
To open the door the user will have to first scan the right tag and then he will have to enter the correct password.
Please try again later.
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.
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.
On scanning the wrong tag or on entering the wrong password the system will deny access.
The aim is to control a door lock without keys but using a smart phone instead.
To open the door the user will have to first scan the right tag and then he will have to enter the correct password.
In this post you are going to learn about how to build an rfid and keypad based door lock using arduino.
Rst pin goes to digital pin 9.
Project this project guide will detail the steps to create an rfid radio frequency identification door lock system using an arduino mega 2560.
This is a simple project made with arduino uno r3.
Mosi pin goes to digital pin 11.
Arduino rfid door lock hardware project setup.
