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.
