单片机1主要负责接收ADC0809转换后的数据，并通过比较产生控制信号并将信号发送给单片机2，而单片机2主要负责接收信号然后通过信号控制两台步进电机的运作从而达到"设计一控制系统，假设有一个太阳能电池板，为了使电池板最大限度的接受光照强度，通过控制器调节电池板的角度使电池板始终正对光线。采用步进电机作为角度调整装置，使系统能上下和左右旋转"目的.-The operation of the microcontroller 1 is mainly responsible for receiving data after the ADC0809 conversion, and by comparing the generated control signal and the signal is sent to the microcontroller 2, and single-2 is mainly responsible for the reception signal and then through a signal to control the two stepper motor so as to achieve " design a control system assume a solar panel to the battery plates to maximize acceptance of the light intensity, the battery plates always light. stepper motor angle adjustment device, so that the system can be up and down and left and right by the controller to adjust the angle of the battery plates rotation purposes.
