# Fun with Sensors

This is the code from my talk at [JSConf.asia 2014](http://2014.jsconf.asia/) in Singapore.

The slides you can find [here](http://www.slideshare.net/janjongboom/fun-with-sensors-jsconfasia-2014).

It's a set of four demo's that you can run on multiple devices and use to demo

fun things to do with sensors. The demo's are:

* Hide and seek, clients can work together to find a WiFi access point

* Theremin, use multiple devices to control oscillator on a server that generates music by leveraging device light sensors

* Orientation, uses orientation data to control a 3D model on a server that mimics behavior of the device in real life

* Juggling visualizer, plots z-axis accelerometer data from multiple devices into a graph

For all this to work you need:

* Host machine

* One or more devices running Firefox OS or Firefox for Android

    (hide & seek is Firefox OS only)

* A WiFi network where all of them are connected to. 3G would work too, but you don't want a large delay.

## I'm lazy, don't want to set up anything

I have hosted a server at http://janjongboom.com:8321.

The clients are at http://janjongboom.com/jsconf-asia/client/.

F.e. to do the juggling thing, open http://janjongboom:8321/devicemotion

in Firefox on your computer. Then open:

http://janjongboom.com/jsconf-asia/client/devicemotion in Firefox on your devices.

## Setting up host machine

1. Get node.js

2. Go into the /server folder and run `node server.js`

3. To open one of the demo's run:

    * Hide and seek: http://localhost:8321/wifi

    * Theremin: http://localhost:8321/devicelight

    * Orientation: http://localhost:8321/deviceorientation-multi

    * Juggling: http://localhost:8321/devicemotion

4. Note the IP address that you are connected to on the WiFi network

## Setting up clients

1. In the /client folder do a search-and-replace. Find `10.10.0.247` and replace it with your own IP.

2. On Firefox OS, use WebIDE or App Manager to install the apps on your phone

3. On Android you need a web server or something on your host machine,

    and then go to that URL in Firefox for Android.

4. Now open the app related to the demo:

    * Hide and seek: wifi-stumbler

    * Theremin: deviceorientation

    * Orientation: deviceorientation

    * Juggling: devicemotion
