This blog documents the creation of a kinetic solar array that was displayed in a gallery last month. The arduino was coded to move a series of large servo motors that map the function of the sun through a day. ( The movement was sped up and a small proximity sensor was also attached to allow people to interact in the gallery setting) Thanks
