Digital Door Lock System Using Arduino

This is a simple project made with arduino uno r3.

Digital door lock system using arduino.

Here the code consists of a combination of digits from 1 to 6. Connect pin 2 vdd or vcc to the 5v of the arduino. First of all we start from the brain of this project which is the arduino uno board. 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.

It will open your door only when the right password is entered and it will start beeping when a wrong password is entered. There are separate keys for locking and unlocking the system. Digital door lock using arduino as thefts are increasing day by day security is becoming a major concern nowadays. 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. 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. One such digital code lock is imitated in this project using arduino board and a matrix keypad. The aim is to control a door lock without keys but using a smart phone instead.

The code for password based door lock security system using arduino keypad is given below. The simply compile it then finally upload it to the atmega328 microcontroller. In this project we will make a digital door lock system with keypad using arduino uno. 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.

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. Smart bt door lock simple arduino project showcase by arun. This article is about a simple digital code lock using arduino. Digital door lock using arduino.

The complete circuit diagram for our arduino based digital keypad door lock project is shown below. Download the library for keypad h from below. Connect pin 4 rs to the pin 9 of the. The arduino board is connected to an lcd and a servo motor.

You can simply copy paste the code using arduino ide. After you learned that procejt you can use that for your own room door or your wardrobe drawer even you can make combination safe.
