1. 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...

  3. Rotation sensor challenge

    Rotation sensor challenge

    Rotation sensors are very important in the field of engineering because they track and measure the motion of rotating objects. The NXT motors and EV3 large motors have built- in rotation sensors that are accurate enough for most purposes, but what if you need something even more accurate? How can...
