Arduino RGB Led Node.js Example

A example for serial communication with Arduino and Node.js to control a Common Cathode RGB LED using an Arduino and 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. The server uses the Express framework and 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

Example Circuit

Incoming data format

The format that is used to configure the colors is R255G255B255\n.
