Place your Boe-Bot so that both IR LED/detector pairs are focused directly at the
center of your electrical tape stripe (see Figure 8-10 and Figure 8-11).
Then, adjust your Boe-Bot’s position (toward and away from the tape) until both
zone values reach the 4 or 5 level indicating that either a far away object is
detected, or no object is detected.
If you are having difficulties getting the higher readings with your electrical tape
course, see Trouble Shooting the Electrical Tape Course on page 289.
