Infrared remote control device with small size, low power consumption, the function is strong, cost low characteristic. Is the widespread use of a close wireless communication and remote control. This design includes the infrared signal transmitter, LED indicator light, dc motor drive several important function module. Based on the analysis of the infrared remote control work, based on AT89C51, design code for infrared remote control circuit, write infrared emitting and receiving procedures; In dc motor of the steering control aspect, this design USES the ends of dc motor control to achieve high and low level of motor steering control; Through the infrared remote control device can also control dc motor start and stop. This design USES the monolithic component infrared remote control motor steering system, simple structure, reliable operation, strong function of the motor to, speed, good control of the timing.
