Resources
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(){
});
});
});
