Check out the DS1338 instead as it has a battery backup switchover built in
and it can work at 3.3V too.
 
The DS1307 is a nice device but suffers from terrible clock drift when I
have used it in the past. I have a design here that gains about 5 mins per
week with it. The DS1338 based device has been almost rock solid. This is
more important if your design is going to be located away from user
intervention to change it often.

Hi,

You can use DS1307 as a RTC.

You can connect it via I2C to any AVR uC.

There are many sample codes available.

I used I2C library by peter fleurry in one of my project.

Use bcd to dec conversion to send the data from RTC to LCD.

For LCD also you can have peter fleurry library.

All the best.

Prashant

Hi dear
I am really looking for a project with atmega 16 or atmega 32 in
codevision for 
real time clock (digital appearance ) connected to lcd and its
schematic.

Thanks in advance for your help
