var five = require("../lib/johnny-five.js"),

board.on("ready", function() {

  // Create a new `potentiometer` hardware instance.
  potentiometer = new five.Sensor({

    freq: 250
  });

  // Inject the `sensor` hardware into
  // the Repl instance's context;
  // allows direct command line access
  board.repl.inject({
    pot: potentiometer

  // "data" get the current reading from the potentiometer
  potentiometer.on("data", function() {
