FastPixel* LPD8806 is an RGB LED strip controller.

    sensor = new upm::LPD8806(10, 7);
    usleep (1000000);

    sensor->show ();

    while (!doWork) {
        // Back-and-forth lights
        scanner(127, 0, 0, 30);        // red, slow
        scanner(0, 0, 127, 15);        // blue, fast
        usleep (1000000);
    }
