ON and OFF (and sleep?)

Wow! I'm much obliged for the plethora of great responses. It's a good lesson: phrase your request succinctly and you'll get a better response. Thanks.

So to summarize helpful ideas I got:

  1. Connect a relay on the power line.
  2. Use AA or AA batteries.
  3. Use a flip-flop
  4. Latching relay to sustain power until Arduino comes up
  5. The pololu proprietary solution
  6. Remove all power draining stuff and just put the Arduino in a sleep state
  7. 555 timer to sustain power

but my favorite, and the one I think I'll try first (I'm extrapolating here)

  1. wire up an off-center motor that, when activated, knocks my little box onto its side, turning off BroHogan's mercury tilt switch. :slight_smile: Seriously, though, thanks Bro, and thanks for the latching circuit diagram. As a SW guy it will probably take me a day to understand how that works, but I am determined to figure it out.

Thanks, all!
