[![devDependency Status](https://david-dm.org/franciscodelahoz/arduino-rgb-led-nodejs-example/dev-status.svg)](https://david-dm.org/franciscodelahoz/arduino-rgb-led-nodejs-example?type=dev)

A example for serial communication with Arduino and NodeJs to control a Common Cathode RGB LED using an Arduino and [Node SerialPort](https://github.com/node-serialport/node-serialport).

## Connecting the RGB Led to Arduino
The project is a web application to control a common cathode RGB LED using Arduino and [Node SerialPort](https://github.com/node-serialport/node-serialport). The server uses the [Express](https://github.com/expressjs/express) framework and [Socket.io](https://github.com/socketio/socket.io) to transmit data in real time between the server and the client.

### Led Connection
The led connection in the hardware is

| Color   | Pin |
| ------- | --- |
| Red     | 9   |
| Green   | 10  |
| Blue    | 11  |
| Cathode | GND |
