Sound input module + UNO board + LED .. Help !

arduinodlb:
This inbuilt function should give you what you need to determine when 10 seconds has passed:

millis() - Arduino Reference

I added this function, however, my time didn't return back to zero. It keeps counting the time.
I need it to count 10 seconds only and then start again from 0 to 10.

Thanks a lot ..
