store data in sd card as well in serial but at different period of time

hi

i have arduino uno board,

my concept is store data in SD card at different time period & serial print at different time period;
and both string format also different.

is it possible?

plz help'''''''

You could open the IDE, click on "File" / "Examples" / "SD", and see if there's anything useful there for you.

As long as you can identify which period is which, and when, you can print whatever, wherever, and whenever it is. I guess you could do this with a clock or simply by counting loop cycles.
