Rfid Door Lock Using Arduino Uno
In this post on arduino tutorial for beginners this topic about how to use module rfid rc522 with arduino uno r3.
Rfid door lock using arduino uno. Next connect the keypad with arduino. The rfid reader module uses the spi interface in order to communicate with arduino. The goal is to open a door by using a specific tag that functions as an access badge. With this simple tutorial we can apply this application to control the huge things in our life.
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. On scanning the wrong tag or on entering the wrong password the system will deny access. Project this project guide will detail the steps to create an rfid radio frequency identification door lock system using an arduino mega 2560. To open the door the user will have to first scan the right tag and then he will have to enter the correct password.
An error occurred while retrieving sharing information. Rst pin goes to digital pin 9. In this post you are going to learn about how to build an rfid and keypad based door lock using arduino. This is a simple project made with arduino uno r3.
Rfid and keypad based door lock using arduino. Smart bt door lock simple arduino project showcase by arun. To open the door the user will have to first scan the right tag and then he will have to enter the correct password. 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.
Miso pin goes to digital pin 12. Arduino rfid door lock hardware project setup. The aim is to control a door lock without keys but using a smart phone instead. Mosi pin goes to digital pin 11.
So we are going to use the hardware spi pins of the arduino uno. Please try again later. This rfid door lock can be made easily at your home and you can install it in any door. 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.
Rfid door lock with arduino. Irq pin stays unconnected. If the wrong tag is scanned the door will stay closed and set off a buzzer. You have seen rfid door lock mechanism in some hotels and other places where you don t need a key to unlock the room.
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. The 4x4 keypad has 8 connections but we don t require the last column of keypad.
