Device Control with Password Protection project is developed for the users to control Electric and Electronic devices with password protection. The user can control all the domestic appliances for example, Light, TV, Fan, Fridge etc using different password.

The user can on and off the devices by giving password through keypad. A LCD display displays the settings and other details given the user. The details set by the user are stored in the microcontroller.

As soon as the user enters the code, the microcontroller receives the signal and accordingly controls the controlling section. The controlling unit drives a corresponding relay in the external electronic circuit. The relay is used as a switch to operate the particular device. By this way the user can control any of the Electric or Electronic devices.

The microcontroller program is written in assembly language. The microcontroller used is PIC 16F73.

This project is used in areas where the devices are to be controlled in a secured manner
