node-dash-button

Place it. Hack it. Press it. Get it.

This module was inspired by this fantastic article by Edward Bensen.

It is a simple library that will allow you to utilize a dash button to emit an event. I am using the same strategy of watching for dash generated ARP requests as the article above.

Installation Instructions

The following should work for ubuntu, the main thing for any os is getting the libpcap dependancy.

# dependancy on libpcap for reading packets
$ sudo apt-get install libpcap-dev
$ npm install node-dash-button 

Find a Dash

To find a dash on your network, run the following from the node-dash-button directory in node_modules:

# you may need to use sudo due to libpcap running in permiscuous mode
$ cd node_modules/node-dash-button
$ node bin/findbutton

It will watch for new arp requests on your network. There may be several arp requests, so press it a few times to make sure. Copy the hardware address as shown below

Example Usage:

//warning this may trigger multiple times for one press
//...usually triggers twice based on testing for each press
dash_button = require('node-dash-button');
var dash = dash_button("8f:3f:20:33:54:44"); //address from step above
dash.on("detected", function (){
	console.log("omg found");
});
