Try Me
The Try Me [Try Me] feature (see page 17) includes several 
programs already prepared for experimenting with the NXT 
and the Motors. For example, try this program controlling 
Motor and Sounds:
As you turn the Motor, a series of sounds in a scale 
will be played. The tone increase one note for every 10 
degrees. Turning the Motor direction toward the right 
(clockwise) increases the pitch. Turning the Motor to the left 
(counterclockwise) decreases the pitch.
Program
You can also use the Program [Program] feature to create 
programs right on the NXT without using a computer.
See the Program section on page 15 to create a program 
using the Motors.
