DIGITAL CALENDER USING ATmega16

Introduction :-
In this project we use ATmega16 controller and a 16x2 alphanumeric LCD. Program is loaded in the ATmega16 and the digital calender is ready to run. This calender is starts from 2013 and ends in 2100. You can reduce delay for seeing results quickly.

Lcd Interfacing :-
see.. LCD INTERFACING WITH ATmega16 IN 4-BIT MODE

ATmega16 :-

Components required :-

10k ohm registance
10k ohm variable registance
8 MHZ crystal oscilltor
16x2 LCD
ATmega16 IC
12v battery
Toggle button
7805 IC
330 ohm resistance
1N4007 diode
1000uf capacitor
Green LED

Circuit Diagram :-

In 4-bit mode ground the first 4 data pins of LCD means pin 7-11. make the connections as shown above.

Code (compiled in CVAVR) :-

(see.. CVAVR TUTORIAL (CODE VISION AVR))

Note :- In CVAVR program window delete all the lines and paste the code given below. because there are so much unnecessary lines.
