Door Lock Security System - ATmega32

The Door Lock Security System project aims to create a robust and secure mechanism for unlocking a door using a password. The project leverages two ATmega32 Microcontrollers, each operating at 8MHz, and is designed based on a layered architecture model for efficient and modular functionality.

System Overview

The project consists of two main components:

  1. HMI_ECU (Human Machine Interface):

    • Equipped with a 2x16 LCD and a 4x4 keypad.
    • Responsible for user interaction, taking inputs through the keypad, and displaying messages on the LCD.

  2. Control_ECU:

    • Incorporates an EEPROM for data storage, a Buzzer for alarms, and a DC-Motor for door control.
    • Manages all processing and decision-making tasks, such as password checking, door opening, and system alarm activation.

Usage

  • Hardware target

    In order to run the code on a real hardware target (ARmega32), follow these steps:
  1. Setup: Connect the components as per the circuit diagram.
  2. Compile: Use an appropriate compiler (e.g., AVR GCC) to compile the provided source code.
  3. Program: Program the ATmega32 Microcontroller with the compiled binary using a suitable programmer (e.g., AVR ISP).
  4. Run: Power up the circuit. The Stopwatch will start counting immediately.
  5. User Interaction: Start by creating a password of 5 digits, then make a choice of either opening the door or changing the password

  • Simulation

  1. Setup: Install proteus 8 professional v10.0 or higher
  2. Install Add-ons: Add the necessary arduino and avr add-ons (Arduino_Proteus_Libraries)
  3. Run: Run the .pdsprj file in the /Proteus Simulation folder in any of the versions
