This project is part of the graduation internship at Arab Academy for Science, Technology & Maritime Transport (AAST) in collaboration with Valeo Egypt.
It implements a secure garage door locking system using an embedded microcontroller and a keypad interface to authenticate users before granting access.
- 3-attempt password entry system.
- Password confirmation via pressing the 'C' key.
- Ability to clear digits before entering the 4th digit using the 'C' key.
- Two types of access:
- Normal User:
1111 - Admin:
2112
- Normal User:
⚠️ Important: Pressing any key other than 'C' after a failed attempt will be counted as an incorrect trial and may lock the system after 3 failures.
- Microcontroller: AVR ATmega32
- LCD Display: 16x2 LCD (I2C or standard interface)
- Keypad: 4x4 Matrix Keypad
- Communication Interfaces:
- SPI
- I2C
- UART
- Atmel Studio 7
- Proteus (for simulation)
- Embedded C
- Power up the system.
- Enter your 4-digit password using the keypad.
- Press the 'C' key to confirm.
- If correct, access is granted.
- If incorrect, two more trials remain.
- You can press 'C' at any time before entering the fourth digit to clear and re-enter the password.
- After 3 incorrect attempts, the system locks and displays an error message.
This project was developed during the internship program at AAST & Valeo Egypt as part of the graduation requirements for Electrical & Electronics Engineering.
