      "description": "An Arduino manages two lasers, a two line LCD display and an MP3 player to provide a simulation of a track-side defect detector.  It counts axles, gives the train's scale speed and length and reports the temperature.\nRandom defect announcements are planned but not yet implemented.\nVisit www.trainelectronics.com for more information\nhttp://www.trainelectronics.com/Arduino/DefectDetector/index.htm",
