Hur man gör en musikal, motordriven glöd-i-the-dark-ghost mobil (16 / 17 steg)

This program drives a unipolar or bipolar stepper motor.
The motor is attached to digital pins 4 - 7 of the Arduino.
The motor should revolve one direction
following a sinusoidal rate of rotation.

The program also allows the user to remotely activate and deactivate the
glowing ghost mobile of doom. It sends control signals to the mobile for 10
during which time the audio from the disk in the CD player will play 10
seconds of audio. After 10 seconds the code will send the pause and skip
command to go to the next track.
