Plants need sunlight to grow, but when we grow plants indoors, there is no guarantee that the plants will get enough sunlight. Because sunlight may be blocked by buildings and other reasons, it is almost impossible for the same place to have sunlight throughout the day. The theme of this project is to make a light-seeking car. The main function of the car is to carry the plant to find the place where the indoor light is strongest, and the car will change its position as the light intensity changes, so as to ensure that the plant can get enough light indoors. While looking for sunlight, the car will automatically avoid obstacles to ensure plant safety.
