Cool! A couple of comments based on the esc examples Rick created last week:

Use destructuring on the J5 import to grab just the classes you need rather than grabbing the parent five object.

Let the board ready handler be bound to board. It is the most likely target for this throughout a J5 program (the REPL, accessing the io object, etc ). In other words, no fat arrow on board.on("ready", function() { ... });.

I was about to say something about grunt examples but I see you just updated your PR so I'm guessing you saw the error.

const {Board, LED} = require("../lib/johnny-five.js");
const board = new Board();

board.on("ready", function() {
  const led = new Led(13);

  // This will grant access to the led instance
  // from within the REPL that's created when
  // running this program.
  this.repl.inject({
    led
  });

  led.blink();
});

LGTM!

If someone wants to do the work of replacing all the occurrences of this with board (where appropriate), we could move the examples to use an arrow in the "ready" handler.
