Requirements

• Node.js
• Libusb for Mac OSX and Linux

Requirements for Mac OSX

Install Node with npm and libusb using homebrew:

$> brew install node
$> brew install libusb

Requirements for Windows

Install Node for Windows and make sure it's added to your PATH environment variable.

Requirements for Linux

$> sudo apt-get install libusb nodejs npm

Raspberry Pi

The apt repositories keep a very old version of NodeJS. Please install the Node ARM Binaries from the official site. Run the following command to confirm the architecture of your Raspberry Pi.

$> uname -m

Addionally, you will need to install libudev-dev rather than libusb.

$> sudo apt-get install libudev-dev -y

Install BlinkStick node module

Install using npm:

$> npm install blinkstick

Getting started

var blinkstick = require('blinkstick');

To get the first blinkstick on your system:

var device = blinkstick.findFirst();

To set the color:

led.blink('random', function(){
    led.pulse('random', function(){
        led.setColor('red', function(){
        });
    });
});
