About the Controller Board
25
The Controller board is the brains of ARobot. It contains circuitry to control the steering and drive mo-
tors, read the whiskers, control LEDs, speaker, buttons, etc. The controller board has a socket that ac-
cepts a Basic Stamp II control computer chip designed by Parallax Inc. www.parallaxinc.com
The Basic Stamp II is programmed with a desktop PC through the serial port in the PBasic Language
which is much like standard Basic but with some interesting additions.

Basic Stamp II Installation
The Basic Stamp II is the computer that controls the robot. It plugs into the controller board. When in-
stalling the Basic Stamp II, remove the battery cable from the controller, then insert the pins into the
socket noticing the pin 1 indicator. Make sure that no pins are bent. Installing the Basic Stamp II in-
correctly may damage it or the controller board. To remove the Stamp, remove the battery cable and
use a small screw driver to pry it up without bending any pins. **NOTICE PIN 1 INDICATORS!!!
