The setup is as shown below we have only added leds to show the state of the lock.
Password based door lock system using arduino and keypad.
The password based door lock system allows only authorized persons to access the restricted areas.
Just compile it and finally upload it to the atmega328 microcontroller.
The entire project is controlled by using the arduino.
It will open your door only when the right password is entered.
Password security lock system using arduino keypad program code.
After learning how the 4 4 keypad with arduino works we can now demonstrate how this keypad can be used to make a simple keyword based door lock.
So a digital code lock can secure your home or locker easily.
You can simply copy paste the code using arduino ide.
Download the library for keypad h from below.
The code is provided for a password security lock system using arduino keypad project.
The code for password based door lock security system using arduino keypad is given below.
Just thought of making a password based door lock system in which you can enter the password via the keypad.
We have used eeprom in the arduino to store the password in it.
A 4 4 or 4 3 keypad can be used to enter the desired password.
The default password stored in it will be 1234.
It was an interesting project which required beginner s level skill in programming and very easy to connect circuit.
On scanning the right tag and on entering the right password it will send us a confirmation message that the door has opened.
As thefts are increasing day by day security is becoming a major concern nowadays.
The simply compile it then finally upload it to the atmega328 microcontroller.
