Michiel B. / FlightSimInstrument-1

This project is about creating an airplane instrument (such as an altimeter) for a flight simulator running on a PC. The code will read in two space-separated \"words\" containing the altitude and airspeed, with units, from a \"USBSerial port\". See my notebook page for details.
