Cash box guard with lighting security system

Nowadays, vaults and cash box recently happen rapidly among our community. The security system that been applied to these vaults are normally pin coded numbers. But, it only protects the vault from being broke into but does not provide a security system that will alert the owner when the vaults are broken. This project namely as Cash Box Guard With Lighting Security System. It created to give a supportive system to the pin coded numbers system. It acts as the secondary security system after the pin coded numbers. The system will be operated when the door of the vault is open. The switch behind the door will activated the light security system that is drive by IC 555. The timer IC are going to turn on the bulb thus the Light Dependent Resistor from Cash Box Guard system detects the light and drive the Piezobuzzer to produce an alarm sound. With this output, the owner will be aware when their vault or cash box were being broken at that time.
