In this activity, use an NXT car equipped with an ultrasonic sensor to navigate without bumping into obstacles such as walls or people.

In this activity, use an NXT brick equipped with two ultrasonic sensors to emulate a Theremin, an electronic instrument. One sensor will change pitch as distance to an object changes, and the other sensor will change volume as the distance to an object changes. The Theremin is meant to be played wit...
