XX () 1 15 7805AT89C51 L293D II Abstract The shoe polisher is the use of a new generation of electrical products, integrated circuit, receiving the infrared emission control, reasonable design, easy operation. The foot is open, oil foot 15 second delay shutdown, automatic work. All you have to do is put my foot shoe polisher, other things are done by it. The design and application of single chip microcomputer to design an automatic shoe machine. Based on single-chip microcomputer automatic shoe machine hardware including voltage transformer, the integrated module 7805, infrared emitting and receiving tube, AT89C51 chip, L293D chip and other components of the power circuit, infrared emitting and receiving circuit, SCM system control circuit, motor drive circuit and display circuit. The normal operation of the circuit is used to control the whole system controlled by single chip microcomputer system, is the core of the whole system. The system mainly through infrared emitting and receiving circuit testing signals, the u
