Electronic Safe with Arduino

This project includes a 6 digit password (123142), that must be entered if you want to unlock the safe. There are 4 buttons to submit characters(1, 2, 3, or 4), an enter button, and a clear screen/lock button. When the safe is unlocked, it will remain unlocked until the button to lock it is pressed. The locking mechanism is simple - a servo motor is mounted to the shoebox, and a slit is cut in the shoebox and the door flap. When in the locked position, the motor is turned in between the openings, making it not possible to open.”
