You may be wondering why I am posting a non-technic Lego brick house on the Mindstorms Community. There is more to this house than meets the eye--some of the functions include an opening garage door and a skylight that opens and closes depending on the lightness or darkness outside. The garage door is controlled by two touch sensors on the side of the house, while the skylight is controlled by a light sensor within the house. When it is dark outside and the skylight closes, a blue light within the house turns on. Enjoy!
