Hi,I'm fairly new to Arduino and programming in general.I recently made a quick sketch that would have a servo lock a door. While searching around for ways to make it more efficient, I read about the Watchdog timer.I'd like to know how the watchdog improves efficiency, as far as I can tell, all it does is protect code from hanging. Can it also be used to make my arduino enter a power save state for ~8 seconds between cycles?
