This ought to be a work putting together most of my previous research and efforts. The hardware is made up of:
- Arduino MEGA main board
- Arduino MEGA IO extension board by DFRobot (with MicroSD socket)
- LCD4884 shield for Arduino
- MTK3389 GPS receiver (with 5Hz update speed)
- OBD-II UART adapter
After being able to record the realtime vehcile data and GPS data, I need a rendering program so that I can view the recorded data graphically. Finally I didn’t take time to make my own one but made use of Google Earth for doing this. I wrote a utility program to convert all the recorded binary data into a KML file which can be loaded into Google Earth.

Finally a video showing my Arduino Mega data logger working in the car.
