Graphical User Interface consists of clickable boxes, and visual representation of the peripherals action is helpful visuals that can allow the user to determine the move on of the operation. In summary, this software is necessary for control over the interface. check port can be used to interface: LEDs - maneuver on or off, display a pattern Motors - first gear or stopping, controlling further operations Sensory devices - such as miniature robots Printer - executing printing operating instructions Scanner - executing scanning...
