millis rollover

Hi I in my sketch use function millis() to make time delay for 5 sec and 10 sec. Is there possibility if the timer millis rollover to have problem in my sketch .Except time delays i do not use any code to make rollover milllis problem fixed. If the rollover problem with the millis timer exist in my sketch what is code to fix at. Regards Riste

It depends on how you use the timer. Rollover problems can be prevented:-

Note that roll over is only a problem when the same code has been running continuously for over 50 days.
