Locker guard based on Arduino Uno

You can protect your locker using this simple locker guard system. This system generates a beep sound whenever someone attempts to open the locked safe. This system generates an alert sound when some light falls on it, in an open condition. If someone tries to open it then defiantly some light will fall inside the locker, that light will be detected by the Light-dependent resistor and the buzzer will generate an  alert beep sound.
