Changing the intensity of an LED using a Potentiometer and Arduino Nano

Circuit:-

Code:-

const int analogPin = 0;
const int ledPin = 9;
int inputValue = 0;
int outputValue = 0;

void setup()
{
  Serial.begin(9600);
}

void loop()
{
  inputValue = analogRead(analogPin);
  Serial.print("Input: "); 
  Serial.println(inputValue); 
  outputValue = map(inputValue, 0, 1023, 0, 255); //Convert from 0-1023 proportional to the number of a number of from 0 to 255
  Serial.print("Output: "); 
  Serial.println(outputValue);
  analogWrite(ledPin, outputValue); 
  delay(1000);
}
