This allows you more control over then a delay with trigger. This library makes this easy by allowing you to create variables (objects) that automatically increase as time elapses. So I wondered if I could write a function that I can just drop in to my sketches. Filename Release Date File Size; A: Task scheduling is handled in the Alarm. If the time for the delay has passed, update will return true. When you use a delay() function in an Arduino sketch, the processor stops everything it is doing until this delay is completed. This number represents the time (measured in milliseconds). Uses millis() and micros(), taking care of any rollovers should they occur.
