Sunlight controlled reflection for lighting up a dark room

This project is focused on taking advantage of the light reflection in order to illuminate a dark room. In order to achieve this objective, a prototype was developed, which consists of a mirror mounted on a base with capabilities of rotating in the X and Y axis, a sensor that allows to know in which direction the sun is located and the necessary program code to maintain the illumination spot in the same position in a room, despite the movement of the sun through the day. Data was obtained through measurements, which allows to conclude that the energy invested in the prototype is lower than the energy needed to illuminate that room.
