Hacking the Code Activity
With the example as a reference, try creating a new sketch to move the TaskBot in
a different-size circle. Remember what we learned from our previous activities and
experiment with different parameters to make the circle diameter larger or smaller.
Challenge yourself to add behaviors. What would it take to make your robot drive in
an oval or a figure eight?
Tip: In the sketch window
the PRIZM library functions
change color when they
are typed or spelled
correctly. Consequently,
if spelled incorrectly they
will not change. In Arduino,
the PRIZM functions are
recognized by the software
as keywords and will turn
orange when the syntax is
correct.
Tip: An example library of
code to help you get started
with this challenge can be
found in the appendix. If you
have a digital copy of this
guide, you can simply copy
and paste the sample code
for each activity into your
sketch window. A digital
download can be found at
