AVR : Interfacing Seven Segment Dispay (Atmega16/32)

Here we had made use of 7 segment common cathode display for the Interfacing. Along with the Atmega16.
Simulation work is done in Proteus Software.
Header file: avr is providing its own header filr "avr/io.h"
                  for using delay in the avr , we had used util/delay.h
This header file can provide the delay in milli and micro seconds.
