NeoPixel LED Strip Server

Overview

This project helps anyone to control LEDs on a NeoPixel LED Strip, thanks to 2 simple HTTP GET / API:

• http://ip:8083/switchAllOff? will switch off all the LEDs

• http://ip:8083/changeLed?ledId=[0-7]&red=[0-255]&green=[0-255]&blue=[0-255]&brightness=[0-100] will change the ledID selected with the color (red, green or blue) and the brightness passed.

• http://ip:8083/changeLedInRange?from=[0-7]&to=[0-7]&red=[0-255]&green=[0-255]&blue=[0-255]&brightness=[0-100] will change the ledId in the range [from,to] with the color provided.

This allows easy integrations with other applications running on the RPi with a simple HTTP/Get command. The project works on Raspberry Pi boards.

How to use it:

git clone the repository 
run as root: sudo node neopixel_server.js 

The server listen on all interface by default: If the LEDs are controlled from applications inside the device, change the code in order to run the server only on localhost. Search and replace the code:

--> app.listen(8083);

with

--> app.listen(8083,'localhost');
