xBoard(TM) v2.0 Sample Programs
------------------------------------
Description : Demonstrate the use of DC motor. Teaches you how to control
the speed and direction od DC motors.
The program starts the MOTOR - A in CW direction with
with Full Speed. Then it changes speed to half.
After that the direction is reversed and speed is again
set to MAX. After some time speed is reduced to 50%
This whole process is repeated again and again.
