Did this experiment a few days back and thought of placing it here today

//Constants:
const int ledPin = 3; //pin 3 has PWM funtion
const int sensorPin = A0; //pin A0 to read analog input
//Variables:
int value; //save analog value
void setup(){
pinMode(ledPin, OUTPUT); //Set pin 3 as 'output'
Serial.begin(9600); //Begin serial communication
}
void loop(){
value = analogRead(sensorPin); //Read and save analog value from potentiometer
Serial.println(value); //Print value
value = map(value, 0, 1023, 0, 255); //Map value 0-1023 to 0-255 (PWM)
analogWrite(ledPin, value); //Send PWM value to led
delay(100); //Small delay
}
