  4. Tomb raider

    Tomb raider

    The idea of this challenge is to have students set up several light sensors to log data over time. After the setup is complete, run the programs, turn off the lights in the room, and have the students leave. Walk around the room near the different sensors with a flashlight....

  6. Light sensor scavenger hunt

    Light sensor scavenger hunt

    How can you determine the light conditions in different parts of a room? Can you find light sensor readings in the range of 0-30? 60-90? 90-100? Can you draw conclusions and make generalizations about light intensity in the room?

  7. Light theremin

    Light theremin

    In this activity, use an NXT brick equipped with two light sensors to emulate a theremin. One sensor will change pitch as the amount of light sensed changes, and the other sensor will change volume as the amount of light sensed changes. The theremin is meant to be controlled with the...
