Digital Door Lock System Using Arduino

Hello dear friends in this project i have tried to explain how to built a door lock security system with an arduino and keypad.

Digital door lock system using arduino.

Smart bt door lock simple arduino project showcase by arun. Digital door lock using arduino as thefts are increasing day by day security is becoming a major concern nowadays. Here the code consists of a combination of digits from 1 to 6. This article is about a simple digital code lock using arduino.

This is a simple project made with arduino uno r3. There are separate keys for locking and unlocking the system. By saddam oct 19 2015 34 digital code lock using arduino security is a major concern in our day to day life and digital locks have became an important part of these security systems. The arduino board is connected to an lcd and a servo motor.

You can simply copy paste the code using arduino ide. Connect pin 1 vee to the ground. Well i have used 4x4 keypad for this project but you can use different models but do not forget to change some parts in the code. Digital door lock using arduino.

In this project we will make a digital door lock system with keypad using arduino uno. The servo motor is used to push lock or pull unlock the latch on the door. First of all we start from the brain of this project which is the arduino uno board. After you learned that procejt you can use that for your own room door or your wardrobe drawer even you can make combination safe.

Digital code lock or digital combination lock are a type of digital locks where a combination of digits characters or both are used for unlocking the lock. Download the library for keypad h from below. The complete circuit diagram for our arduino based digital keypad door lock project is shown below. The simply compile it then finally upload it to the atmega328 microcontroller.

Connect pin 4 rs to the pin 9 of the. This idea helps in the security of the locker s in the bank list of the components required for the project. Connect pin 3 v0 to the middle pin of the 10kω potentiometer and connect the other two ends of the potentiometer to vcc and gnd. Simply it s a digital door lock system which helps in the security of the door lock with the use of a digital keypad and by using the arduino uno board.

It will open your door only when the right password is entered and it will start beeping when a wrong password is entered. One such digital code lock is imitated in this project using arduino board and a matrix keypad.
