Embedded Based Digital Calendar LCD Display

Abstract

This project is developed for the users to use a digital calendar. The main parts of this project are key pad, microcontroller unit and LCD display. In normal operation mode, the LCD display displays the Current time, date and day like an ordinary calendar. The user can set the time, date and day using the key pad. When the user sets the timings, the settings will be displayed in the LCD display. The settings are stored in the microcontroller memory. When the function key is turned on, the microcontroller sends data to the LCD display to display the current time, date and day. If necessary, the user can modify the settings using the key pad. This project is very cheap and compact. Since microcontroller is used, the operations will be very accurate. The microcontroller program is written in Assembly language and the microcontroller used is PIC 16F73.
