I am currently working on a project that will use two separated electronic motors driving the back wheels of a go kart (see stolen drawing below). As an intermediate step I am building a small scale model to test first. I am looking at using an Arduino Mega with a seeed studio motorshield to drive two small electric motors from radioshack. The arduino will take in a signal from two potentiometers (one that simulates a throttle, and one that simulates steering angle). Based on these inputs the arduino will change the output to the motors and allow them to act like a mechanical differential.
I have experience coding in C as well as some other languages, but I am relatively new to Arduino Programming. Does anyone have some leads on where I can find a similar project or some helpful resource that may help get me started on this? (Google searches are not yielding anything helpful, unfortunately) The project will eventually be expanded to incorporate some type of traction control, but I will worry about the basics first and try to familiarize myself a little more before I take more advanced steps.
Thanks in advance!
