so give it a try... go to download section and DOWNL...[more]

doubt in rtc
Forum -> Project Addition or Changes
thanks for the advice...

wanted to know why exactly time flag and alarmflag used...and also the increament and decreament flag.
can we do without using switches.i.e is it for setting time in clock or setting time for alarm......[more]
