Door_Security_System_AVR

Implemented via AVR atmega32 MCU with 8 MHz internal clock frequency.

Project Description

• The door is unlocked using a password entered via a keypad:
    i. The door opens by rotating the DC motor Anti-clockwise for 15 seconds.
    ii. It is then held open for 3 seconds.
    iii. Then it is closed by rotating the DC motor clockwise for 15 seconds.
  
• If the user entered a wrong password 3 consecutive times:
    i. The keypad accepts no input for 1 minute.
    ii. A buzzer and a LED are triggered for 1 minute.
  

Project Specifications

• Human Machine Interface Micro-controller Unit:
    - Responsible for interaction with the user.
    - System initialization: It prompts the user to enter a new password and confirm it.
    - It send the password input to the CONTROL ECU to be confirmed.
    - No input is accepted from keypad if the password is entered 3 consecutive times.
  
• Control Micro-controller Unit:
