Run this example from the command line with:

node eg/altimeter-BMP180.js

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

board.on("ready", function() {
  // By including a base `elevation` property, the values
  // received will be absolute elevation (from sealevel)
  var alt = new five.Altimeter({
    controller: "BMP180",
    // Change `elevation` with whatever is reported
    // on http://www.whatismyelevation.com/.
    // `12` is the elevation (meters) for where I live in Brooklyn
    elevation: 12,
  });

  alt.on("change", function() {
    console.log("altimeter");
    console.log("  feet         : ", this.feet);
    console.log("  meters       : ", this.meters);
    console.log("--------------------------------------");
