  6. Random motion

    Random motion

    The code will run Motor A in a random direction (via a Random-Comparison Block combination), at a random speed, for a random amount of time. The motor speeds will fall between 0-100 and the time will fall between 0-3 seconds. Resources Random Motion.rbt (ZIP)

  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...

  8. Things that go bump

    Things that go bump

    Design and construct a car and program it to travel in a straight line until it hits a wall. Once it hits the wall, program the car to reverse direction and continue until it hits another wall at which point it stops.   Tip: What sensors can be used to...

    NXT-A-Sketch

    Just like its little red counterpart, the Etch-A-Sketch®, the NXT-A-Sketch lets you turn two knobs to draw your picture. However, rather than using a stylus and aluminum powder, the LEGO NXT model is entirely digital, making use of the Servo motors and the LCD display. Building To build the NXT-A-Sketch,...
