|| '''Slide 4:'''

'''About Solar tracking system'''
||
* <div style="margin-left:1.27cm;margin-right:0cm;">'''Solar tracking system'''<span style="background-color:#ffffff;color:#001d35;"> is used </span>to increase the energy output of solar panels</div>

* <div style="margin-left:1.27cm;margin-right:0cm;">It is done by automatically adjusting their orientation to follow the sun's path</div>

|- style="border:1pt solid #000000;padding:0.176cm;"
|| '''Slide:5'''

'''Code file'''
||
* <div style="margin-left:1.27cm;margin-right:0cm;">The following code file is required to practise this tutorial</div>
* <div style="margin-left:1.27cm;margin-right:0cm;">'''Solar Tracking System.zip'''</div>
* <div style="margin-left:1.27cm;margin-right:0cm;">This file is provided in the Code Files link of this tutorial page</div>

|- style="border:1pt solid #000000;padding:0.176cm;"
|| Type

https://electroblocks.org/
|| Let us open the '''ElectroBlocks''' website in the Chrome browser.
|- style="border:1pt solid #000000;padding:0.176cm;"
|| Only narration
|| Let us open a new blank project.
|- style="border:1pt solid #000000;padding:0.176cm;"
||

Click on the Projects icon located on the toolbar.

Select the Choose File option.

Locate and open the solar tracking system.xml file.

A pop-up window will appear on the screen.Click OK.

|| Extract the zip file downloaded in the download folder.

In this tutorial, we will see how to load an existing saved project and work on it.

On the toolbar Click on the '''Projects''' icon.

Select the '''Choose File option.'''

And open the Solar Tracking System.xml file in the extracted zip folder.

A pop-up window will appear on the screen.Click '''OK'''.

The''' Solar Tracking System''' project is loaded with the required blocks for this experiment.

|- style="border:1pt solid #000000;padding:0.176cm;"
||
|| This is the complete setup of the '''Solar Tracking System.'''
|- style="border:1pt solid #000000;padding:0.176cm;"
|| Point to simulation window and zoom the circuit

Point according to the narration
|| The circuit is displayed in the simulation window.

Here, two Light sensors are used to detect the light.

The servo motor rotates according to the movement of the sun.
|- style="border:1pt solid #000000;padding:0.176cm;"
|| Only narration
|| Now, let’s explore the code and the corresponding blocks to understand how it works.
|- style="border:1pt solid #000000;padding:0.176cm;"
|| Click on the code icon
|| Click on the '''Code''' icon.

|- style="border:1pt solid #000000;padding:0.176cm;"
|| <nowiki>#include <Servo.h> // Includes the Servo library for controlling servo motors</nowiki>

|| '''Servo.h''' is the the Servo header library, which provides built-in functions to control servo motors
|- style="border:1pt solid #000000;padding:0.176cm;"
|| Servo servo_2; // Creates a servo object

|| Creates a Servo object named servo_2, which is used to control a connected servo motor.
|- style="border:1pt solid #000000;padding:0.176cm;"
|| double spoint = 0;

|| '''Spoint''' is the variable which stores the current angle of the servo motor.
|- style="border:1pt solid #000000;padding:0.176cm;"
|| pinMode(A5, INPUT);

pinMode(A4, INPUT);

|| In the working area, two analog setup blocks are displayed.

These blocks are used to configure the analog sensors.

The sensors are connected to analog pins A5 and A4.

In the code window , within the '''void setup() '''function, pins A5 and A4 are defined as input.

In the setup blocks, sensor readings of 512 and 1024 are shown.

These values represent the analog readings from the photo sensors.

|- style="border:1pt solid #000000;padding:0.176cm;"
|| servo_2.attach(2);

|| The servo motor is connected to pin 2 in the block so that this code is generated.
|- style="border:1pt solid #000000;padding:0.176cm;"
||
|| In the working area, the servo motor is linked to a variable called '''spoint'''.
|- style="border:1pt solid #000000;padding:0.176cm;"
|| if (((double)analogRead(A5) < (double)analogRead(A4))) {

spoint = (spoint + 9);
delay(1000); /
|| Let us see the condition in the <span style="color:#000000;">First IF-THEN Block.</span>

It checks whether the analog reading from A5 is less than the reading from A4.

If true, the servo motor arm is rotated by 9 degrees to move towards the light.

A short delay is added to slow down the movement, making the rotation smooth and realistic.
|- style="border:1pt solid #000000;padding:0.176cm;"
|| if (((double)analogRead(A5) > (double)analogRead(A4))) {

|| Now in the second IF-THEN Block, it compares the analog values at A5 and A4,

If the light is more on the A5 the servo rotates to the left.

|- style="border:1pt solid #000000;padding:0.176cm;"
|| spoint = (spoint - 9);

|| If the light on A4 is more when compared to A5 then the motor rotates to the right side.
|- style="border:1pt solid #000000;padding:0.176cm;"
||
|| Let’s check the output using the simulator.
|- style="border:1pt solid #000000;padding:0.176cm;"
|| Click on '''Home''' icon on the tool bar.

Click on the '''Play''' button
|| Click on '''Home''' icon.

Now click on the '''Play''' button to start the simulation.
|- style="border:1pt solid #000000;padding:0.176cm;"
|| Point to simulation window
|| We can see the servo motor rotates from 0 to 126 degrees when sensor1 value is less than sensor 2.
|- style="border:1pt solid #000000;padding:0.176cm;"
|| Only narration.

Click on the first setup sensor reading number box and change it to 1024.

Similarly Click on the second setup sensor reading number box and change it to 512

Again click on the '''Play''' button to start the simulation

Point to simulation window

Only narration
|| Let us check the output of the project if sensor1 value is greater than sensor2 value.

Click on the '''first setup sensor''' reading number box and change it to 1024.

Then Click on the '''second setup sensor''' reading number box and change it to 512.

Next change the '''spoint''' value to 126.

Click on the '''Play''' button to start the simulation.

Now we can see the servo motor rotates from 126 to 0 degrees.

'''Assignment''':

* <div style="margin-left:1.27cm;margin-right:0cm;">Add an LED to pin number 4 in the existing project instead of servo motor</div>
* <div style="margin-left:1.27cm;margin-right:0cm;">If the value from Sensor 1 > Sensor 2, the LED should turn ON</div>
* <div style="margin-left:1.27cm;margin-right:0cm;">If the value from Sensor 1< Sensor 2, the LED should turn OFF</div>

|| As an assignment, please do the following
