PotControl_LED by BREVIG http://alexanderbrevig.com
This demonstrates how to control two LEDs using a Potentiometer. The ledBelow lights up when the potentiometer is below middle, and the ledAbove lights up when potentiometer is above middle

    #include <Potentiometer.h>
    #include <LED.h>

    LED ledBelow = LED(12); //object LED below  at digital 12
    LED ledAbove = LED(13); //object LED above  at digital 13
    Potentiometer potentiometer = Potentiometer(2);       //a Potentiometer at analog in 2

    void setup()
    {
      potentiometer.setSectors(2); //split the Potentiometer into two sectors
    }

    void loop()
    {
      if (potentiometer.getSector()==0)
      {
        ledBelow.on();
        ledAbove.off();
      }
      else
      {
        ledBelow.off();
        ledAbove.on();
      }
    }
