Addendum - Pin # change on the Arduino

If you're actually using the code, you may have noticed that I changed the signal pin numbers (t_chassis.h). They were originally 12 (steering) and 13 (drive). However, pin 13 also connects to the Arduino's onboard LED, so I'd prefer to leave that one unused, or connect it to an LED on the outside of the robot for debugging purposes. Thus, I have changed the signal pins to pins # 11(steering) and #12(drive). I had to make a new adapter board to accommodate this. The only difference is that the connector going to the Arduino has four pins instead of three, plugging into digital pins GND, 13, 12 and 11. Pin 13 is currently not connected to anything. Aide from the pin # changes, everything else is the same.
