Your Turn – Improving performance
You can improve your Boe-Bot’s performance by commenting some of the subroutine
calls that were designed to help the Boe-Bot back away from obstacles and then turn to
avoid them. Figure 6-6 shows an example where the two
commented from the
detect a shadow. Then, when only individual photoresistors detect shadows, the
subroutine calls are commented so that the Boe-Bot only turns in response to a shadow.
