Assignments:

• View the videos in the video section of this lesson.
• Read and follow the instructions in Robotics with the Boe-Bot  Chapter 3. 
• Complete the Boe-Bot activities assigned by your instructor. If self-study, do all the “Your Turn” parts for each activity in the chapter.  Fill out the Observations section in this lesson for each Activity. (Note: It is only by typing in the commands that you truly begin to understand programming. So don’t short change yourself.)
• Review the Key Points or FAQs below.
• Use the Observation again to Answer the questions at the end of the chapter.
• Check your answers.
• When complete, turn in the Observations Word Doc to your instructor (print, email or other method defined by your instructor). Self-study students can optionally send to a parent, mentor or friend.

Key Points or FAQs:

What is the FREQOUT command? What electrical component is it used in conjunction with?

The FREQOUT command stands for Frequency Out and is used with the piezo-electric speaker.

What units is the Duration argument of the Pulsout command measured in?

They are measured in Microseconds.   A microsecond is a millionth of a second.  It’s abbreviated µs. For example, 8 microseconds is abbreviated 8 µs.

What command do you use to get input from the debug terminal?

The DEBUGIN command places the value you type in the Debug window into a variable.  For Example:

DEBUGIN DEC pulseWidth 

This command will assign the value typed into the debug window to the variable pulseWidth.
