/* SparkFun Inventor's Kit
 Example sketch 02 -- POTENTIOMETER
 
 Measure the position of a potentiometer and use it to
 control the blink rate of an LED. Turn the knob to make
 it blink faster or slower!
 
 This sketch was written by SparkFun Electronics,
 with lots of help from the Arduino community.

int sensorPin = A0;    // The potentiometer is connected to analog pin 0                  
int ledPin = 13;      // The LED is connected to digital pin 13
int sensorValue;	//We declare another integer variable to store the value of the potentiometer

{
  pinMode(ledPin, OUTPUT);
}

void loop() // this function runs repeatedly after setup() finishes

  sensorValue = analogRead(sensorPin);    

  digitalWrite(ledPin, HIGH);     // Turn the LED on
  delay(sensorValue);             // Pause for sensorValue in milliseconds
  digitalWrite(ledPin, LOW);      // Turn the LED off
  delay(sensorValue);             // Pause for sensorValue in milliseconds
