Password Based Door Lock System Using Arduino Simulino Uno

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.

Password based door lock system using arduino simulino uno.

In this project we will make a digital door lock system with keypad using arduino uno. The code for password based door lock security system using arduino keypad is given below. The below table shows how to connect your arduino with keypad. A 4 4 or 4 3 keypad can be used to enter the desired password.

Connect your hardware as shown in circuit diagram above and now upload hex file generated from below code to the arduino uno board. By using this system you will be able to unlock a door for 5 seconds. Const byte rows 4. We need a keypad for password input and manually lock our customized door locker.

Circuit of this project is very simple which contains arduino keypad module buzzer servo motor and lcd. It will open your door only when the right password is entered. 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. 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. 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.

The password based door lock system allows only authorized persons to access the restricted areas. After 5 seconds the electrical door opener will be automatically be locked. In this guide i will help you to make it easily on breadboard by using the arduino uno board and i will give you some extra tips on how you can make your own arduino based custom circuit. Arduino controls the complete processes like taking password form keypad module comparing passwords driving buzzer rotating servo motor and sending status to lcd display.

The entire project is controlled by using the arduino. It will open your door only when the right password is entered and it will start beeping when a wrong password is entered. This is a door lock security system made with arduino.
