Soft potentiometer tutorial

1-  int sensorPin = A5;    // select the input pin for the potentiometer  int ledPin = 13;      // select the pin for the LED  int sensorValue = 0;  // variable to store the value coming from the sensor  void setup() {    // declare the ledPin as an OUTPUT:    pinMode(ledPin, OUTPUT);  }  void loop() {    // read the value from the sensor:    sensorValue = analogRead(sensorPin);    // turn the ledPin on    digitalWrite(ledPin, HIGH);    // stop the program for <sensorValue> milliseconds:    delay(sensorValue);    // turn the ledPin off:    digitalWrite(ledPin, LOW);    // stop the program for for <sensorValue> milliseconds:    delay(sensorValue);
