Detailed Description

• ID: grovelinefinder
• Name: Grove Line Finder
• Category: color
• Manufacturer: seeed
• Connection: gpio

UPM module for the Grove 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 Grove Line Finder sensor on digital pin D2
  upm::GroveLineFinder* finder = new upm::GroveLineFinder(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);
    }
