VariableBlink-Serial

/*
  Blink with variable frequency
  
  Turns on an LED on for x seconds, then off for x seconds, repeatedly.
  x is given by variable resistor:
 * left and right pins of resistor to respectively +5V to analog and 0 
 * Middle Pin to A0
 */
  
// Pin 13 has an LED connected on most Arduino boards.
// Pin 11 has the LED on Teensy 2.0
// Pin 6  has the LED on Teensy++ 2.0
// Pin 13 has the LED on Teensy 3.0


int led = 13;   // output of the LED
int thisSensor = 0;  // input A0 of the resistor


// the setup routine runs once when you press reset:
void setup() {
  //start serial connection
  Serial.begin(9600);
  // initialize the digital pin as an output.
  pinMode(led, OUTPUT); 
}


// the loop routine runs over and over again forever:
void loop() {
  int sensorReading = analogRead(thisSensor);
  Serial.println(sensorReading);

  digitalWrite(led, HIGH);   // turn the LED on (HIGH is the voltage level)
  delay(sensorReading);               // wait for a second
  digitalWrite(led, LOW);    // turn the LED off by making the voltage LOW
  delay(sensorReading);               // wait for a second
