The Velleman MK129 Crawling Microbug minikit is easy to build and fun to watch crawl around your house. The miniature crawling robot always heads for the light and will stop in total darkness. The light sensitivity is adjustable with trimmer potentiometers and the microbug’s LED eyes light up to indicate the direction it’s heading. You can choose between two different walks and adjust the speed. The Crawling Microbug minikit circuit operates on batteries and has an on board on/off switch.
