What is Standard Firmata?

Priming the Board with Firmata

npm install johnny-five

Installing Johnny 5

var five = require("johnny-five"),board = new five.Board();

board.on("ready", function() { //board is ready to use });

Enabling the Board

board.on("ready", function() { (new five.Led(13)).strobe(3000);});

Controlling an LED Light

board.on("ready", function() { servo = new five.Servo(10); servo.to( 90 ); this.wait(1000, function() { servo.sweep(); });});
