Using Johnny-Five with Grove's Compass (HMC588L) component on the Intel Edison Arduino Breakout. This shield and component will work with any Arduino pin-out compatible hardware platform.

Run this example from the command line with:

node eg/grove-compass-edison.js

var five = require("johnny-five");
var Edison = require("edison-io");
var board = new five.Board({
  io: new Edison()
});

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

  // Plug the HMC5883L Compass module
  // into an I2C jack
  var compass = new five.Compass({
    controller: "HMC5883L"
  });

  compass.on("headingchange", function() {
    console.log("headingchange");
    console.log("  heading : ", Math.floor(this.heading));
    console.log("  bearing : ", this.bearing.name);
    console.log("--------------------------------------");
  });

  compass.on("data", function() {
    console.log("  heading : ", Math.floor(this.heading));
    console.log("  bearing : ", this.bearing.name);
    console.log("--------------------------------------");
  });
});
