Responding to an Object Detection on the Side
This code for side IR object detection works about the same as the examples from the
previous activity. They can be added to the
example program's main routine. They will make the SumoBot respond by rotating in
place to turn toward objects it detects on either side. If an object is on the SumoBot's left
side, the
makes the SumoBot rotate left until either one of the front IR detectors sees the object.
