Tracked vehicle controlled by accelerometer of mobile phone

This video is of one of my hobby projects. What I've done is written a application in Basic4Android that runs on any Android device. This application gets the accelerometer data for two axis.

This data is translated into two variables that represent the direction and speed of both motors. These two variables are send to the Arduino using the bluetooth shield. Arduino translates these two variables are converted to a PWM signal that is send to the home build dual speedcontroller.
