This program plays a C major scale through the NXT.

This example demonstrates how to play a song in the NXT code.

This program emits a beeping sound as an NXT vehicle backs up.  As the vehicle gets closer to another object (say, a wall or another vehicle), the beeping gets faster.  This program uses a while loop containing a case structure in order to accomplish this.  Such a program could be useful in the development of a parking aid for a car.

This example demonstrates the use of the sound sensor by reading in sound intensity and displaying a corresponding message to the NXT screen.
