I build a digital alarm clock,
I program the alarm clock to direct the alarm clock one time for every day in the week
My problem is that I don't know how to store the clock in the memory
​

 

You need to provide much more information for anyone to provide a sensible answer.

eg. parts used, is it software or a pure hardware system etc...

 

I programming in C and use RTC 12C887 & 8051 micro controller

 

I will glad to recieve help
