Employee code is displayed on LCD screen. EPROM has been used to store the password in the default location even not to be erased in the absence of power supply. In this project we use I-Button as a key to a system for security purpose.

This system is developed to provide security system using micro controller , digital lock is a access control system which will  authorize persons to access a secured data.
