Hi all! I'm working on a self-contained project that will be battery powered. I want it to come "on" when the user presses a pushbutton, but then turn "off" again after, say, 10 minutes of inactivity. This device must be very power conservative, because it won't be very feasible to swap out the 9V…

ON and OFF (and sleep?)

I think I get the relay, but what does the switch connect to? The same relay? Is the relay controlled (somehow) by both this "power" switch and an Arduino digital pin? Pardon my density, please.
