Door-Locker-Security-System

Developing a system to unlock a door using a password.

• Drivers used to build the project: GPIO, Keypad, LCD, Timer, UART, I2C, EEPROM, Buzzer and DC-Motor
• The used Microcontrollers in the project: ATmega32.
• The project is designed and implemented based on the layered architecture.

Human Machine Interface(HMI_ECU):

This unit is just responsible of the interaction with the user through a Keypad that takes inputs, either an option or the password, and Liquid Crystal Display(LCD) screen that displays messages to the user.

• The architecture layer of HMI_ECU unit:

Control_ECU:

This unit is responsible of all the processing and decisions in the system like password checking, comparing to that saved in the external Electrically Erasable Programmable Read-Only Memory (EEPROM), opening and closing the door through a DC-motor, and activating the system alarm.

• The architecture layer of Control_ECU unit:
