Abstract
In this paper, the design of the Automatic Sun Traces is introduced. This instrument is used to track the sunlight; and it consists of Photosensitive Sensor module, digital control module, A/D conversion module, button control module, SCM control module. Through the stepper motor group A and B of the rotation to control the position of the dark, to determine the location of the sun. The instrument I have designed is significantly more convenient than the traditional ones; hence potentially it can be much more widely used in future.
Furthermore, during the design, we have gotten more familiar with knowledge in the fields of digital control based on SCM, data acquisition and processing, as well as circuit design.
