#nodebot with express, sparkjs and particle-io

A proof of concept for communicating between a Particle Photon board and an express server via events.

The express server will first publish an event named Foo with a value. The server will then listen for any events named Bar
On the event of Bar, the server will emit Foo again - with a value.

The device will listen for any events named Foo. On the event of Foo, the device will :

• turn the LED on or off
• emit Bah with a value.

##Requirements

Make sure you've flashed your Photon with the voodoospark firmware.

It is also recommended that you store your Particle token/device ID in a dot file like .particlerc so they can be accessed as properties of process.env.

Make sure you include your login/password creds at the bottom of device.js and server.js. You could also just store these in your .particlerc.

##Usage

Install the dependencies:

% npm install

Because I'm a slave to ES6, you'll need to make sure you have babel installed:

% npm install -g babel

First run the device.js script so the Photon is ready and listening. I've included the port the micro USB is connected to.
To find you port run ls /dev/tty.* (Mac)

% babel-node index.js device.js /dev/cu.usbmodem1421

Now the device is ready, run the server in another terminal window:

% babel-node server.js

If you've wired things up correctly, you should have a flashing LED that turns on every time Bar is emitted. I just included the button for funsies using particle-io.
