The Axidraw can be manipulated and controlled through Processing.
This is a brief look at how this can be implemented, download and unzip the files to continue.
If this is your first time using an Axidraw, I recommend checking out this tutorial first.
This project makes use of an Arduino, a car chassis, a bluetooth module, and an android phone to make a Remote Control Car that is controlled by tilting the phone like a steering wheel. This post is a high level overview of the project and requires a solid understanding of coding.
