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 hands, but any object that changes the amount of light that the sensors pick up can be used.
What other sensors could be used instead of light sensors?
