Such as the following requirements, what do you need any modules or components list, please industry leaders and experts tell, please please very urgent,

Requirements: detection of sunlight, and through the SCM driving a stepper motor rotation, makes the photosensitive resistance affected by vertical light irradiation (like a sunflower, in order to improve the utilization rate of solar energy) in the absence of light (night) there is a light intensity detection, if the light intensity not reached the critical value (set a threshold) system of dormancy, the morning reached the critical value, the system automatically start the spotlight,

Track light source detection cycle is set to 15 minutes (once every 15 minutes to detect the sun and correcting this part involves the DS1302 clock chip)


Do with photoresistor light data acquisition unit, the system start-stop detection device available photosensitive diode, with stepping motor and stepping motor driver module the spotlight, a motor driven horizontal direction, vertical direction driven by a motor,

I saw a very simple circuit, two light diode add some simple components, it is not necessary to do so complicated
