Electronic Password Lock drawer

                                       Electronic Password Lock drawer


Objective: Build a electronic password lock system for a drawer to replace the old keylock.


 Reason:
Keylocks requires designated keys to open the drawer, without the key there is no other way the open it safely. It is more complicated if there are multiple users as more keys would be needed.

However in the case of the electronic password lock, user(s) only have to know a simple set of numbers to open the drawer.

Security is also more flexible with the electronic password lock. User(s) may change the password easily, without having to change the entire lock.
