Beaglebone Led Brightness

First, let's import Cylon:

var Cylon = require('cylon');

Now that we have Cylon imported, we can start defining our robot

Cylon.robot({

Let's define the connections and devices:

  connections: {
    beaglebone: { adaptor: 'beaglebone' }
  },

  devices: {
    led: { driver: 'led', pin: 'P9_14' }
  },

Now that Cylon knows about the necessary hardware we're going to be using, we'll tell it what work we want to do:

  work: function(my) {
    var brightness = 0,
        fade = 5;

    every(0.05.seconds(), function() {
      brightness += fade;
      my.led.brightness(brightness);
      if ((brightness === 0) || (brightness === 255)) { fade = -fade; }
    });
  }

Now that our robot knows what work to do, and the work it will be doing that hardware with, we can start it:

}).start();
