[0047] In the present invention, the microcontroller uses Arduino Uno, which has abundant digital and analog input and output pins, is easy to develop, and is convenient for quickly realizing project functions; the light sensor uses a photoresistor, which is low in price and sensitive to changes in ambient light intensity.

[0048] In the present invention, the code of the microcontroller is:

[0049] const int sensorPin = A0;

[0050] const int in1 = 2;

[0051] const int in2 = 3;

[0052] int sensorValue;

[0053] int threshold = 512;

[0054] void setup(){

[0055] pinMode(in1,OUTPUT); pinMode(in2,OUTPUT);

[0056] Serial.begin(9600);

[0057] }

[0058] void loop(){

[0059] sensorValue=analogRead(sensorPin);

[0060] Serial.print("Light intensity value: ");

[0061] Serial.println(sensorValue);

[0062] if(sensorValue>threshold){

[0063] digitalWrite(in1,HIGH);

[0064] digitalWrite(in2,LOW);

[0065] }else{

[0066] digitalWrite(in1,LOW);

[0067] digitalWrite(in2,HIGH);

[0068] }

Then the read light intensity value is compared with the preset threshold threshold; if the light intensity is greater than the threshold, the in1 pin is set to a high level and the in2 pin is set to a low level through the digitalWrite function, so that the motor rotates forward, drives the electrode to adjust to the appropriate position, and reduces the fill light; if the light intensity is less than or equal to the threshold, the in1 pin is set to a low level and the in2 pin is set to a high level, so that the motor reverses, and the electrode position is adjusted to increase the fill light. A delay of 100 milliseconds is added after each judgment to prevent the motor from frequently switching directions due to slight changes in ambient light.

[0072] In the present invention, since the light angles in the morning, noon and evening are different, the angle between the photovoltaic panel 5 and the ground needs to be adjusted according to the time period. Ordinary technicians in this field know that the photovoltaic panel 5 is basically set to face south, but the angle between the photovoltaic panel 5 and the ground is changed according to the amount of light in each area to obtain more electricity and maximize the benefits; taking Beijing as an example, the best angle between the photovoltaic panel 5 and the ground in the morning is 30°, the best angle between the photovoltaic panel 5 and the ground at noon is 35°, and the best angle between the photovoltaic panel 5 and the ground in the afternoon is 33°; the present invention can determine the forward and reverse rotation time or number of rotations of the motor according to the transmission efficiency of the motor 205 through the turbine 2033, the worm 2032 and the rack 204, and then adjust the angle between the photovoltaic panel 5 and the ground. The present invention can adjust the angle between the photovoltaic panel 5 and the ground automatically, and the benefits are maximized.

[0073] In an exemplary embodiment, Figure 4 As shown, an angle mark is provided on the surface of the rack 204 facing the opposite direction of the motor 205 .

[0074] In the present invention, the angle mark is the angle between the photovoltaic panel 5 and the ground displayed by the rising rack 204 when the photovoltaic panel 5 is parallel to the ground, which is convenient for adjustment; when the application location of the present invention is not flat, the first lifting support leg 1 cannot adjust the photovoltaic panel 5 to be parallel to the ground. At this time, it is necessary to measure the angle between the photovoltaic panel 5 and the ground. On this basis, the angle mark displayed by the rising rack 204 is added to obtain the angle between the photovoltaic panel 5 and the ground.

[0076] The embodiments described above are only descriptions of the preferred modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
