For software testing, I thought it would be helpful to create a simulator. For simplicity I chose Data Dashboard. The tablet app is powered by a basic web based XML protocol. There is a good deal of information about creating and parsing this format online, so I won't elaborate. For now, the actual car also uses this format to accept commands, though I will likely switch to something else once the simulator no longer proves useful.

Currently I display the speed and direction of the car. For debugging purposes the direction is shown in both a text and raw enumeration format.
