Culloden Elementary
April 13, 2006
Today the students built a traffic gate similar to those seen in a parking garage. Once the gate was built,
they programmed it to rotate up, stay for a period of time, and rotate back to the original closed position.
The students then decided to add a light sensor to the build. Shown below, the light sensor continuously
reads a dark reading from the black Lego piece. The students manipulated the program so that when the
light sensor read a brighter reading than the black, then the gate would rotate as before.
