what MCU is it on the shield
I decided on using an Atmega328 because it had the I2C hardware built in and I wasn't sure how big the code was going to be.
type 2 alarm: longitude exceeded; with 2 long registers one can define an allowed area - similar for latitude; (and height) if both long & lat alarms set define a square (don't go outside the cave)
I've been pretty busy building these things...apparently they're getting pretty popular (why oh why did I use 0402 parts!!!!)
I do plan on releasing the code soon.
