Fake Sensor

We have been programming over the internet on SENSORS CITY.

It is exciting to get data over the internet while in a science class.

Part of the fun is to see the Monorail move closer and farther away.

Using a motor as a sensor seems counter intuitive.
However one time I wanted to demonstrate the use of data logging using
RoboLab and did not have a sensor with me.  I did however have a motor.
Writing a program in Investigator using a light sensor on input 1
and placing the motor on input 1 gives good though interesting results.

Holding the motor still gives a reading of 100 and letting it run gives a reading of 0.
Students tried to make an "M" for Merry Christmas.
