The Reverse Geocache Puzzle

Early this summer, the friend who first introduced me toAArduino amazed us with the news that he was moving to France to get married. Once I recovered from the surprise, it occurred to me that putting together some sort of Arduino-based wedding present might be a uniquely fitting thanks for his years of friendship and for helping get me started in this delightful enterprise. And so after weighing several ideas a I didn't fancy adding some ugly techno-junk to the pretty collection of tea cozies and china sets a I finally settled on building the device I describe here: a puzzle box that won't open until it is taken to a certain location.

To better understand my conception, let's fast forward and imagine the gift opening. The new couple, freshly back from their honeymoon, remove the wrapping to reveal a book-sized wooden box elaborately carved with elephant images. (I didn't carve it; I bought it that way atAWorld Market.) Mounted into the lid, perhaps incongruously, are an illuminated button, a small display, and a mysterious module that sharp-eyed readers might recognize as a GPS. There's also some kind of connector tucked away on the box's left side. More about that later.

What do they make of all this? It's hard to guess, but naturally I imagine they might try to open it up and take a look inside. When they do, however, they find the lid stuck tight a it seems to be latched from the inside. Will they push the button? Pretty buttons are awfully hard to resist, so let's assume so.
