Because it is characterized by smart at a high level, design with simplication and convenience, low expense and high reliability. It was widely used in the household electric appliances, industry and aviation field. Meanwhile, our society has focused widely on its research. DC motor was widely used in common life, we do not simply take it as a motor equipment, and we need a efficient and convenient way to begin or start motor and regulate its speed. The wide use of infrared remote control and the mature of 51-MCU technology make DC motor smart, thus, we can connect a remote control to it for any time, which is in man-machine separation. In order to control DC motor in time and accurately, we should measure speed firstly. Photoelectric sensor is used to measure and control the speed of DC motor in time. The person who has remote control equipment can regulate speed in time, according to the speed displayed. Based on the demand of market, My topic design a system of infrared remote control for DC motor, with the factors of simplication, convenience and low expense. System uses 51-MCU as control chip to send and receive infrared remote control signal, the keys drive infrared light-em
