or atleast triggering it? i gutted one of those birthday cards with the sound device in it because i thought it'd be a good thing to learn to get the sound out of them. but with no help from google im stuck.
well more like geese? ha!
i was thinking maybe just using a sound sensor to go towards to sounds of the geese..
would that be the best way?i dont think infared would be the best since the geese are outside and it could sometimes be bright.
