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.GroveLineFinder finder = new upm_grovelinefinder.GroveLineFinder(2);
        // check every second for the presence of white detection
        while (true) {
            boolean val = finder.whiteDetected();
            if (val) {
                System.out.println("White detected");
            } else {
