The 3D Map Control project lets you control the Google Earth web browser plug-in with a Wii Nunchuk connected to an Arduino development board. A photograph and a video demonstration of the 3D Map Control project, along with source code and instructions that you can use to build your own 3D Map Control, are available here.
3D Map Control is a project for the Arduino Development Environment that uses the Arduino development board to read, decode, and transmit data received from the Wii Nunchuk to a computer. A simple Processing/Java application running on the computer reads the Wii Nunchuk data from the Arduino development board and makes it available to any modern web browser through a simple web service.
After watching a recent episode of Hak5, which showcased Google Maps GPS Mashups, I was inspired to finally do something with some of my own GPS data. I had GPS data from a canoe trip taken last year and a road trip from a few years ago stored on my handheld GPS with which I had always planned to do something, but just hadn’t had the motivation until now. While a little simpler than the project described on the show, my initial goal was to draw the GPS track data in Google Maps annotated with waypoints drawn as map markers. The markers would be used to mark specific locations with descriptive text and images.
