Password Based Door Lock System Using Arduino Simulino Uno

After 5 seconds the electrical door opener will be automatically be locked.

Password based door lock system using arduino simulino uno.

It consists of 16 keys soft switch 4 keys in rows r1 r2 r3 r4 and 4 keys in columns c1 c2 c3 c4 when a key pressed it establishes a connection in between the corresponding rows and columns. The below table shows how to connect your arduino with keypad. You can simply copy paste the code using arduino ide. Const byte rows 4.

Just thought of making a password based door lock system in which you can enter the password via the keypad. Download the library for keypad h from below. So a digital code lock can secure your home or locker easily. Password based door lock system using arduino simulino uno code include include initialize the library with the numbers of the interface pins liquidcrystal lcd 9 8 7 6 5 4.

Arduino controls the complete processes like taking password form keypad module comparing passwords driving buzzer rotating servo motor and sending status to lcd display. In this project we will make a digital door lock system with keypad using arduino uno. By using this system you will be able to unlock a door for 5 seconds. It will open your door only when the right password is entered and it will start beeping when a wrong password is entered.

Circuit of this project is very simple which contains arduino keypad module buzzer servo motor and lcd. We need a keypad for password input and manually lock our customized door locker. The password based door lock system allows only authorized persons to access the restricted areas. It will open your door only when the right password is entered.

It was an interesting project which required beginner s level skill in programming and very easy to connect circuit. The code for password based door lock security system using arduino keypad is given below. A 4 4 or 4 3 keypad can be used to enter the desired password. This is a door lock security system made with arduino.

The simply compile it then finally upload it to the atmega328 microcontroller. The entire project is controlled by using the arduino. About the 4 4 keypad.
