DiscRover: Bug Report & Troubleshooting Ideas

Mistake in Motor Controller Diagram: In Chapter 9: DiscRover, Pg. 278, Figure 9.6, the pin-outs for the Motor Controller are incorrectly labeled. The label that reads:

"Motor 1 to GND on Motor I/O"

should read:

"Motor 1 to Left Motor Negative"

and the one that reads:

"Motor 2 to GND on Motor I/O"

should read:

"Motor 2 to Right Motor Negative"

In other words, the wires attached to these pins go to the negative motor wires on the motors themselves, not to the negative (or GND) pin on the motor I/O on the OOPic microcontroller.

Switch Clarification: In the book, we were somewhat unclear about figuring out what terminals on a switch you should connect to if the switch has more than two. This should clear things up.
