One of the most common mistakes in robotics projects is trying to make all the parts
work together in one fell swoop. The end result is usually a programming bug that's too
difficult to find. It's best to make sure each part of the project works before integrating it
into a larger system. With this point in mind, this activity is separated into four steps:
Step 1 - Rebuild, Test, and Trouble-Shoot the IR Detection System
Figure 3-1 shows the circuits for IR detection and user indicators from Robotics with the
Boe-Bot, Chapter 7, Activity #2, and Figure 3-2 shows a way to build these circuits with
wiring diagrams.

Build the circuits shown in Figure 3-1 and Figure 3-2.
Test the circuits following the instructions from Robotics with the Boe-Bot,
Chapter 7, Activity #2. You will use both TestIrPairsAndIndicators.bs2 and
IrInterferenceSniffer.bs2.
Rebuild, test, and trouble-shoot the IR detection system by following the
steps in Robotics with the Boe-Bot, Chapter 7, Activites #1 and #2.
Test the roaming with IR object detection and IR interference programs
that were introduced in Robotics with the Boe-Bot, Chapter 7, Activity
#5.
Modify the program so that you can control roaming speed with a
DEBUGIN
Integrate the roaming with speed control function into the IR remote
application program that supports keypad entry of large numbers.
