Windows

Via @ThomasDeutsch on https://github.com/rwldrn/johnny-five/issues/48#issuecomment-7696662

Install Node.js 0.10.x 32 bit (unless anyone can confirm success with 64 bit)
Install Visual Studio Express 2010 32 bit (make sure you have the C++ dependencies checked)
Install Python 2.7.3
Open up cmd (Start > Run.. > cmd) and enter set PATH=%PATH%;C:\Python27
Install node-gyp npm install -g node-gyp

Hello World

Generally Arduino boards (Uno, Mega, Leonardo, Fio, Mini) come pre-flashed with the compiled StandardFirmata firmware. In most cases, getting started is as simple as...

mkdir nodebot && cd nodebot;

npm install johnny-five;

Now open your text editor and create a new file called "strobe.js", in that file type or paste the following:

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

board.on("ready", function() {
  // Create an Led on pin 13
  var led = new five.Led(13);

  // Strobe the pin on/off, defaults to 100ms phases
  led.strobe();
});

Make sure the board is plugged into your host machine (desktop, laptop, raspberry pi, etc). Now, in your terminal, type or paste the following:

node strobe.js

Success should look like this

Trouble Shooting

If the above didn't work as expected, make sure that StandardFirmata is installed on the board:
- Download Arduino IDE
- Plug in your Arduino or Arduino compatible microcontroller via USB
- Open the Arduino IDE, select: File > Examples > Firmata > StandardFirmata
- Click the "Upload" button.
- If the upload was successful, the board is now prepared and you can close the Arduino IDE.
Sometimes Windows systems will fail to compile native dependencies, if you run across this case try:

npm install johnny-five --msvs_version=2012
