This Arduino project implements a simple safe/locker system using a keypad, LCD display, LED, relay, and a buzzer. Users can input a password through the keypad, and based on the correctness of the password, the system will either open the "safe" or trigger an alarm.
- Input password via keypad
- Display text on an LCD display
- LED and relay activation upon correct password entry
- Alarm (red LED and buzzer) upon incorrect password entry
- Countdown timer after 3 unsuccessful attempts
- Password change functionality with automatic EEPROM storage
- Arduino Uno Board
- Keypad
- LCD Display
- Green LED (for successful attempt)
- Red LED (for unsuccessful attempt)
- Buzzer (for alarm)
- Relay (to simulate safe opening)
- EEPROM (for password storage)
Include a wiring diagram or textual description of how the components are connected to the Arduino.
