pitsco TETRIX PULSE

Experiment with the Line Finder Sensor on different surfaces and different heights
to see how the sensor reacts.
Extension Activity
With the example as a reference, try creating a new sketch to use your Line Finder
Sensor. Remember what you learned from your previous activities and think of
additional creative actions to perform based on the condition of the Line Finder
Sensor.
Real-World Link
There are many uses for a robot that can follow a line. Automated robots are being
developed to follow lines to deliver materials within hospitals. In the future, they
could also move materials around warehouses or transport goods.
