Finally got my Arduino dual LED matrix clock working. Time is kept by DS1307 RTC module which I got on eBay. To demonstrate scrolling capability I programmed it to scroll current date every minute. Also time can be set with two switches (I didn't have any buttons so I used those for now). Next step is add Alarm functionality and Wave shield which can play sounds during alarms. I should have just barely enough inputs for this on my Arduino Uno board.
