Description: A digital safety box project controlled by an ATmega32 microcontroller. The password is entered through a keypad. If correct, a welcome message is displayed on the LCD; if wrong, the system denies access and shows the remaining attempts on a 7-Segment display, along with a status LED.
Components & Technologies:
•Microcontroller: ATmega32
•Input: 4×4 Keypad
•Output: LCD 16×2, 7-Segment, LED
•Programming Language: C
My Role:
•Designed the circuit using Proteus and connected all components.
•Programmed the microcontroller to verify the password and manage attempts.
•Added user-friendly messages on the LCD for better interaction.
Impact: Demonstrates the integration of hardware and software to build a practical security system, with potential use in lockers or smart locks.
