In this paper, the design is with the single chip microcomputer as the core of automatic tracking controller. The system is mainly composed of the signal acquisition part, the signal conditioning part, a control circuit and a drive circuit. The signal collection circuit composed of photosensitive resistance sensors to collect light signal, signal conversion circuit with voltage follower LM324 convert the change of light intensity to the change of the voltage, through the voltage comparator LM393 produce high and low level control stepping motor rotation; Control circuit use the AT89S52 as the main control device, output different control signals to the driving circuit; Driving circuit use the ULN2003 as driver stepper motor. Is obtained by simulation debugging, physical test, the error rate is less than 5%, in order to realize the efficient utilization of solar energy.
