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("--------------------------------------");
});
});
