Door Locker Security System

This project is a door locker security system that uses a password to lock and unlock a door. It is designed for embedded systems applications and uses an AVR microcontroller, a keypad, an LCD screen, a buzzer, and a DC motor.

Technologies

This project was created using:

• AVR
• Proteus 8 Professional
• C language
• I2C
• Dc-Motors
• PWM
• UART
• Buzzer
• Timers
• Keypad
• Lcd

Launch To run this project, you need to:

Clone this repository to your local machine https://github.com/ZiadSheriif/Door-Locker-Security-System .

Open the project folder in eclipse .

Build the project and generate the hex file.

Open the Proteus simulation file in Proteus 8 Professional.

Load the hex file into the microcontroller in Proteus.

Run the simulation and interact with the keypad and LCD screen.

Scope of functionalities

• This project has the following functionalities:

1. Setting a new password: The user can enter a new password using the keypad and confirm it by pressing ‘#’.

2. The password should be 5 digits long and should not start with ‘#’.

   • If the password is valid, it is saved in the EEPROM memory and a confirmation message is displayed on the LCD screen.
   • If the password is invalid, an error message is displayed and the user can try again.

3. Locking and unlocking the door:

   • The user can lock or unlock the door by entering the correct password and pressing ‘#’.
     1. If the password is correct, the DC motor rotates clockwise or anti-clockwise to lock or unlock the door respectively, and a success message is displayed on the LCD screen.
     2. If the password is incorrect, a failure message is displayed and the buzzer sounds for one second.

4. User has three attempts to enter the correct password before the system is blocked for one minute.
