Temp reading code for Johnny-FIve

var five = require("johnny-five");
var board = new five.Board();

// !! Seems to read too high a temp.

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

  // Create an analog Thermometer object:
  var temp = new five.Thermometer({
    pin: "A3", 
    freq: 1000
  });

  temp.on("data", function() {
    console.log("celsius: %d", this.C);
    console.log("fahrenheit: %d", this.F);
    console.log("kelvin: %d", this.K);
  });

});

This was a demo of code that didn't work as expected. It turns out I needed to initialize the temperature sensor like this:

  var temp = new five.Thermometer({
    controller: "LM35",
    pin: "A3", 
    freq: 1000
  });
