UPM module for the Line Finder sensor. It outputs a digital signal indicating whether it is detecting black on a white background, or white on a black background.

  // Instantiate a  Line Finder sensor on digital pin D2
  upm::LineFinder* finder = new upm::LineFinder(2);
  
  // check every second for the presence of white detection
  while (shouldRun)
    {
      bool val = finder->whiteDetected();
      if (val)
        cout << "White detected." << endl;
      else
        cout << "Black detected." << endl;

      sleep(1);
    }
