Attach the Brightness Sense block to the
Minimum Think block, and also attach a Knob
Sense block. Now, if you turn the Knob Sense
block all the way counterclockwise (left), then
the Minimum Think block tells the Drive Action
block, “zero”, because this is the smaller of
the numbers it’s getting. If you turn the Knob
Sense block all the way clockwise (right), then
the Minimum Think block will tell the Drive
Action block whatever number it’s getting
from the Brightness Sense block. With the
Minimum Think block, the Knob Sense block
acts like an on-off switch.
17. Use the Blocker Block to Separate Two Parts of a Robot
The dark green Blocker Think block passes
power but does not allow numbers to flow
through it. Use it to build a robot with two
parts that don’t talk to each other. Here’s
an example: One half of the robot is a
Lighthousebot with a spinning light; the other
half is a robot that chirps when it sees the
light from the Lighthousebot.
The Lighthousebot is Knob Sense block that
controls the speed of a Rotate Action block,
and on top of that, a Flashlight Action block
that points outward (sideways). When you turn
the Knob Sense clockwise (to the right), the
light goes on and spins.
