The project is quite simple based on Arduino, there are two platforms, one with a LDR looks for the coordinates where the intensity of the light is higher and tells to the other how to orientate some solar cells in order to get the maximum light intensity. Although the project in very simple, it lets me learn how to use the beams, and even I can get more complexity adding Zigbee communications (the next step). One thing you could find interesting it's how lovely match Makerbeam with standard servos!.
