Therefore, ornamental fish is many families first indoor decorations. However, with the social development, people work, in an increasingly fast pace of life, people in the enjoyment of ornamental fish fun at the same time, often forgotten ornamental fish feeding work, resulting in ornamental fish feeding time irregular, feed uneven problems, resulting in the ornamental fish get sick or even die. This paper based on the basic concept of intelligent home, around the key problems of household aquarium automatic feeding system to carry out design work. The concrete design content is as follows:(1) On the basis of investigation and Research on the structure of domestic fish tank in the current market, a kind of automatic food feeding mechanism is designed, which can satisfy the function of the fish food storage, the quantity of food, the regulation of food intake and so on.(2) According to the design of the automatic out of food structure, with DSP as the core unit, the development of automatic control system of food, including the stepper motor control, fish food shortage alarm and other aspects of the function.(3) To facilitate the function of human
