Acknowledgment

At this moment of accomplishment, we are presenting our work with great pride and pleasure, we would like to express our sincere gratitude to all those who helped us in the successful completion of our project. First of all, we would like to thank our HOD Prof. Rupesh Dubey who provided us with all facilities and amenities for the development of our project. We are exceedingly grateful to our project Professor, Mr. Rajesh B Ahirware who gave us constant guidance and throughout this journey of turbulence.

We also sincerely thank all other faculties of department of Electronics and Communication for their constant and encouragement for our project.

We would also like to thank our parents and friends for their over whelming and whole hearted encouragement and without which this would not have been successful.

ABSTRACT LED's are a fantastic way to illuminate any kind of sign, be it lettering or s. LED Dot-Matrix Displays are a common sight nowadays on streets, malls, buildings, parks and other public places. It is a way of visual information where large LCD and other display become too much expensive. While the display we are using in our project are very cheap and ready to use. The system is comprised of an 8x8 dot matrix display with an interface circuit to a Arduino nano. It also comprises an executive program that runs on the Arduino for the display control of characters, decorative pattern or messages on the display . We can use these display for displaying any information or for even in bright daylight conditions can use an Indoor Advertising Display. The display board displays any character that is through programing of Arduino, which is interfaced using USB to a microcontroller that initializes the led driver MAX7219. The advantage of this project is that size of the display board can be increased row wise and column wise without making any changes in the circuitry since display board is the repetition of a small independent module. We can even extend its display content by making different zones and giving many animations to display. In our project we are using matrix display foe displaying class time table by interfacing the RTC for time keeping.
