General Info (Information not valid yet)

Arduino is an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software. It's intended for artists, designers, hobbyists, and anyone interested in creating interactive objects or environments.

Arduino can sense the environment by receiving input from a variety of sensors and can affect its surroundings by controlling lights, motors, and other actuators. The microcontroller on the board is programmed using the Arduino programming language (based on Wiring) and the Arduino development environment (based on Processing). Arduino projects can be stand-alone or they can communicate with software running on a computer (e.g. Flash, Processing, MaxMSP).

Setting up Arduino Uno and LinuxMCE to be able to control a RGB LED string

In the following I want to give an overview what needs to be done to have LinuxMCE control a RGB LED (string) through an Arduino. The string is within brackets as the only added to the Arduino to be able to control a ledstring is some mosfets and a powerblock.

First is setting up Linuxmce.

For now define Arduino as a vendor via Advanced -> Device Templates. Select the "Add Manufacturer" button and provide "Arduino" as manufacturer followed by save and close.

Define a new template for the Arduino Uno (which I am using atm)

Advanced -> Device Templates, selected "Add device template". Name the template "Arduino Uno", select Implements DCE, Device Category is "Interfaces - Specialized #97". Specify that your device is controlled via category "Device Category:Core" ("Computers - Core"). Otherwise the driver will not be started on the core. As I am using an Ethernet shield select "Is IP based", set "Comm Method" to Ethernet and under "Device data" add #69 TCP Port (int). Give the TCP Port the value "69", set it to required and allowed to modify.

Now set up the rest of the template according to http://wiki.linuxmce.org/index.php/How_to_add_your_own_GSD_device
