Once you have the parts, you can wire them into the Breadboard AppMod using
the diagram shown in Figure 6-21. While it is not very hard to wire, I found that it
took me a bit of time to plan it out correctly. I suggest that when you are wiring the
10-LED bargraph display to the BS2 you start with bit “P7” and work your way back
to “P0.” This should give you a bit more space to put in the wiring.
To test out the application you can use the code below. It is found in the
C:\tabrobotkit\Cylon Eye
subdirectory of your PC’s hard drive. When you first program the robot, you might
want to take out the commented code that “Stops the Robot from Running.” This
way you will be able to test out the application code without having to use the remote
control to stop the robot when it is on your workbench.
