LockBox

This is my programmed lockbox with an electronic keypad lock. 
It comes with a mini power on/off switch inside the box to turn on the locking devices. Once power-up, the user will close the drawer and the locking devices (two servo motors) will activate the lock. A blinking yellow led indicates that a key is being pressed. The user will have to match 6 correct combinations of keys in order to unlock this box. No time limit is allowed here. 
Once the correct keys are being pressed, the door will unlock and the green led will lit up. To resume the locking mechanism, just close the drawer and press any keys.
