MICROCONTROLLER BASED DIGITAL CALENDAR

ABSTRACT Microcontroller has actually revolutionized the world economy as virtually every facet of life is benefiting in one way or the other on the great impact of Microcontroller  today.Meanwhile,the technology of Microcontroller has gone long way of which monitoring and interfacing of real world devices to Microcontroller systems can not be left out. There is the need for this because virtually every home now has a Microcontroller .This project covers the steps involved in the development of control software that is able to monitor as well display Calendar in a digital manner and the development of the hardware involved for the interfacing.This project has a good explanation of the Microcontroller port  pin layout and how to interface devices using the port. There is a detailed explanation of the pin layout and functions and how the interface can be programmed to send and receive data from the port using visual Basic, c++, java language, With this technology, you can easily monitor and display time, date, month, year .
