//This is a sketch to turn on an led attached to in 13
//once a potentiometer gets to a certain level

const byte ledPin = 13;      //led attached to pin 13
const byte potPin = A0;      //potentiometer attached to pin A0

void setup()
{
  pinMode(ledPin,OUTPUT);   //led is an output
  Serial.begin(9600);            // initialise serial port
}

void loop()
{
  int potRead = analogRead(potPin);       //read input from potentiometer
  int potValue = potRead / 4;                  //convert input from potentiometer value between 0 and 255
  digitalWrite(ledPin, potValue >= 125 ? HIGH : LOW);
  Serial.println(potValue);                       //print the value of the potentiometer on a new line
}

I have not compiled nor run this code.
