Rfid door lock using arduino uno.
Miso pin goes to digital pin 12.
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.
Easy user interface just one rfid tag needed whether delete or add tags to memory.
This is a simple project made with arduino uno r3.
Smart bt door lock simple arduino project showcase by arun.
The 4x4 keypad has 8 connections but we don t require the last column of keypad.
So we are going to use the hardware spi pins of the arduino uno.
Rfid door lock with arduino.
Mosi pin goes to digital pin 11.
In this post you are going to learn about how to build an rfid and keypad based door lock using arduino.
Please try again later.
Rfid and keypad based door lock using arduino.
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.
Project this project guide will detail the steps to create an rfid radio frequency identification door lock system using an arduino mega 2560.
On scanning the wrong tag or on entering the wrong password the system will deny access.
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.
The rfid reader module uses the spi interface in order to communicate with arduino.
If the wrong tag is scanned the door will stay closed and set off a buzzer.
Irq pin stays unconnected.
The aim is to control a door lock without keys but using a smart phone instead.
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.
Arduino rfid door lock hardware project setup.
You have seen rfid door lock mechanism in some hotels and other places where you don t need a key to unlock the room.
The i2c pins on arduino uno and arduino nano are a4 a5.
Next connect the keypad with arduino.
Unlocks a door controls a relay actually using a rc522 rfid reader with spi interface on your arduino.
In this post on arduino tutorial for beginners this topic about how to use module rfid rc522 with arduino uno r3.
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.
With this simple tutorial we can apply this application to control the huge things in our life.
Rst pin goes to digital pin 9.
To open the door the user will have to first scan the right tag and then he will have to enter the correct password.
