Cat Dissuader

I have left the Dissuader disconnected for a few days now, and there have been no further "incidents". I think it's worked.

I finished putting all the pieces together and wrote a little code to tie it all together. It waits 5s after a motion event to let the cat get nice and settled, triggers a 1s burst, waits for 10s to let it clear the field of view and let the PIR settle, then goes back to waiting. Testing seems to indicate it should work well; now to see if any actual training occurs....

Switching VIN as I originally planned isn't going to work. With a 9V 1A wall wart, the motor startup current is too high and resets the Arduino. Dedicating a second power supply to drive the motor and switching it through a relay works, and will isolate circuit ground from any inductive spikes when the motor stops.
