ARDUINO CODE

int potPin = A0; // Potentiometer is connected on Analog Pin A0
int ledPin = 9;  // LED is connected on Pin No. 9
int potValue;    // Variable to store potentiometer value
int ledValue;    // Variable to store LED brightness value

void setup() {
  pinMode(ledPin, OUTPUT); // LED pin mode is OUTPUT
  Serial.begin(9600);      // Initialize serial communication
}

void loop() {
  potValue = analogRead(potPin);     // Read potentiometer value (0-1023)
  ledValue = map(potValue, 0, 1023, 0, 255); // Map to LED brightness (0-255)
  analogWrite(ledPin, ledValue);     // Control LED brightness
  Serial.println(potValue);          // Print potentiometer value to serial monitor
  delay(100);                        // Small delay for stability
}
