A Node.js Library to Interact with Blinkt

Install

npm install node-blinkt

Usage

var Blinkt = require('./Blinkt'),
	leds = new Blinkt();

leds.setup();
leds.clearAll();
leds.setAllPixels(0, 156, 0, 0.1);
leds.sendUpdate();

Methods

setup()

Connects to the GPIO and sets the GPIO pin modes. Must be called before any other commands.

clearAll()

Sets all pixels to white.

setPixel(pixelNum, red, green, blue, brightness)

Sets the specififed pixel to the passed rgb and brightness level. The pixelNum is an integer between 0 and 7 to indicate the pixel to change.

setBrightness(pixelNum, brightness)

Sets the brightness level between 0.0 (off) and 1.0 (full brightness) for the specified pixelNum. The pixelNum is an integer between 0 and 7 to indicate the pixel to change.

setAllPixels(red, green, blue, brightness)

Sets all pixels to the passed rgb and brightness level.

sendUpdate()

This method is the most important. You can set pixels colours as much as you want but they will not update until you call this method.
