Introduction

If you need an intermediate GPS project to tickle your fancy, we've got one ready to go. In a previous tutorial, we slapped some boards together to see our GPS locations on an OLED Screen. It was a great learning experience, but we need something more. Today we'll do some more good 'ol board slappin', and we'll save multiple coordinates in a KML file and take over the world! Okay, not take over, but we can easily see collections of coordinates all over the world with Google Earth.
