Adding Real Time Clock ( RTC Module) in your project

Hello Guys ! Adding RTC Real Time Clock in your Project is necessary if accurate time requirement in project is needed. I bought this RTC module only in 5$ from amazon. It has DS3232 Real Time Clock circuit powered by 3 Volt Lithium cell which is enough to power the module for years.

I connect it to arduino duemillanove. And after setting the time it is now showing continuously real time.
