• 1 Make a diagrammatic sketch for the device showing the outer shape of device

3. Download the library of LED LiquidCrystal_I2C

4. Write the code and modified it Arduino using Arduino IDE

// Include the Servo library to control a servo motor

#include <Servo.h>

// Variable to store the LDR sensor value

int LDR_Value = 0;

// Include the LiquidCrystal_I2C library for the LCD display

#include <LiquidCrystal_I2C.h>

// Initialize the LCD with I2C address 0x27, 16 columns, and 2 rows

LiquidCrystal_I2C lcd_1(0x27, 16, 2);

// Create a Servo object to control the servo motor on pin 9

Servo servo_9;

void setup() {

  // Initialize the LCD with 16 columns and 2 rows

  lcd_1.begin(16, 2);

  // Set pin 13 as an input for mode selection (Automatic/Manual)

  pinMode(13, INPUT);

  // Set pin A0 as an input for the LDR sensor

  pinMode(A0, INPUT);

  // Begin serial communication at a baud rate of 9600

  Serial.begin(9600);

  // Attach the servo to pin 9 with a pulse range of 500 to 2500 microseconds

  servo_9.attach(9, 500, 2500);

  // Set pin A1 as an input for manual control of the servo

  pinMode(A1, INPUT);

  // Display "Solar tracker" on the LCD

  lcd_1.print("Solar tracker");

}

void loop() {

  // Check if pin 13 is HIGH (Automatic Mode)

  if (digitalRead(13) == HIGH) {

    // Reinitialize the LCD

    lcd_1.init();  

    lcd_1.backlight();  // Turn on the LCD backlight

    lcd_1.print("Automatic Mode");

    lcd_1.setCursor(5, 1);  // Move the cursor to the 2nd row

    delay(1000);  // Wait for 1000 milliseconds (1 second)

    // Read the value from the LDR sensor

    LDR_Value = analogRead(A0);

    // Display the LDR value on the LCD

    lcd_1.print("LDR=");

    lcd_1.print(LDR_Value);

    delay(1000);  // Wait for 1000 milliseconds (1 second)

    // Send the LDR value to the serial monitor

    Serial.println(LDR_Value);

    // If LDR value is less than 500, move the servo to 80 degrees

    if (LDR_Value < 500) {

      servo_9.write(80);

    }

    // Otherwise, move the servo to 105 degrees

    else {

      servo_9.write(105);

    }

  }

  // Manual Mode

  else {

    lcd_1.init();  // Reinitialize the LCD

    lcd_1.backlight();  // Turn on the LCD backlight

    lcd_1.print("Automatic Mode");

    lcd_1.clear();  // Clear the LCD screen

    lcd_1.print("Manual Mode");

    // Map the analog input from A1 to a value between 82 and 105 degrees for the servo

    servo_9.write(map(analogRead(A1), 0, 1023, 80, 105));

    delay(100);  // Wait for 100 milliseconds (0.1 second)

  }

}

5.verify the code and upload it to Arduino using Arduino IDE  

• The Electrical circuit simulation on TinkerCad

2. make a wiring diagram for the circuit on tinker CAD by :

• add breadboard, Arduino, 

• LDR Sensor

Connect one leg of the LDR to 5V (Arduino).

Connect the other leg of the LDR A0 (Arduino).

Connect the Ground to GND (Arduino).

• connect the LED

 (GND (LCD) → GND (Arduino),

VCC (LCD) → 5V (Arduino)

SDA (LCD) → A4 (Arduino)

SCL (LCD) → A5 (Arduino)

• connect the Servo Motor 

Red Wire (Servo VCC) → 5V (Arduino)

Brown Wire (Servo GND) → GND (Arduino)

Orange Wire (Servo Signal) → Pin 9 (Arduino)

connect the Potentiometer Connections 

Middle Pin (Potentiometer) → A1 (Arduino)

One Outer Pin (Potentiometer) → 5V (Arduino)

Other Outer Pin (Potentiometer) → GND (Arduino)

connect the Slide Switch

1. • Pin 13 (Arduino) → Breadboard (Button or Switch)

•  alternatively and connect them to power and GND too.

6. wiring the circuit according to the sketch in thinkercad   

6.make the circuit  for the device (like the wiring diagram shown above on tinker CAD) and check its functionality 

5. cut the cardboard to build the outer shape of the device taking into consideration the place of Arduino opening,  LDR Sensor, Potentiometer, toggle switch, LCD Screen  and servomotor 

the device consists of 5 components: the box containing the circuit components and the upper room containing the shaded device.

7.verify the code and upload it to Arduino using Arduino IDE  

9.make a place for  all component then attach its .

8. build the shaded device and add the circuit to it ( LDR Sensor, Potentiometer, slider switch, LCD Screen  and servomotor ). 

Burning in wire so the plastic is melten 

The damaged potentiometer has not given any response in any position.
