The Art of Motion Control
"It is a simple task to control small electrical signals which are carried by the wires attached to the printer port of IBM-compatible computers. As with all computer information, these digital signals ("bits") are either "on" or "off." Very basic motion control can be accomplished by simply using these signals to turn on/off more powerful devices (eg. the electric valves in "Pipedream")."
