The simply compile it then finally upload it to the atmega328 microcontroller.
Smart door lock system project using arduino.
We ll discuss the arduino code and circuit design later in this tutorial.
Smart bt door lock simple arduino project showcase by arun.
This will signal the arduino to lock the door.
For locking we use the digitalmultiwrite method from library to write high value to d0 and low value to d3.
Make sure you get a fingerprint sensor that works with the arduino through the serial communication.
The code for password based door lock security system using arduino keypad is given below.
The aim is to control a door lock without keys and using a smartphone to accomplish this.
We don t use keypad or complicated mechanical elements and these are advantages of this system.
More about einzigartig arun this is a simple project made with the arduino uno r3 the aim is to control a door lock without keys and using a smart phone to accomplish this the communication medium will be the internet wifi module esp8266.
The default pins for serial communication on the arduino uno are pin 0 rxd and pin 1 txd of the board but we are going to use other pins for serial communication.
Probably you have seen smart locks for doors that have a keypad or use a fingerprint to set the door lock or unlock.
Just thought of making a password based door lock system in which you can enter the password via the keypad.
This will signal the arduino to unlock the door.
This is a simple project made with the arduino uno r3.
The aim is to control a door lock without keys but using a smart phone instead.
For the proper working demo check the video at the end.
Download the library for keypad h from below.
I have already posted an tutorial about the same project with bluetooth module you can refer it for any clarifications.
It was an interesting project which required beginner s level skill in programming and very easy to connect circuit.
You can simply copy paste the code using arduino ide.
Similarly for unlocking we ll write low value to d0 and high value to d3.
First of all connect the fingerprint sensor to the arduino uno.
This is a simple project made with arduino uno r3.
