Personally I would use Xbee. 

Using Xbees is as simple as calling Serial.println().  If you are already sending data via USB I assume you are just making the same calls.

The cheapest shipping to Croatia is 15 dollars, so no thanks.

eBay is my only option and I'm looking for reliable Micro or Lenonardo board.

Surprised you cannot simply order direct from Arduino in Ivrea, Italy.  You are not that far away from there.   They sell Micros for €18.

The Big Bagpipe has a number of arduinos connected together  http://www.thebigbagpipe.com/home/concept

At one time there was a  "dual core" DIY Drone http://diydrones.com/profiles/blog/show?id=705844:BlogPost:40459

Someone also made an "ExtraCore library for Arduino"  http://hackaday.com/2012/08/31/dual-core-arduino-for-more-pins/

Adafruit sells a Micro for $25

Actually this was posted on Adafruit  recently  Arduino MK802 Based Mobile Web Server Robotic Platform Controlled via javascript with node.js http://www.adafruit.com/blog/2012/12/24/arduino-mk802-based-mobile-web-server-robotic-platform-controlled-via-javascript-with-node-js/

One way you could do this is to mount an Android phone that controls an Arduino.  The phone could also run a web server app that serves up all the html5/javascript/whatever goodness he desires.   

There are tons of examples of Arduino's being controlled by Android phones  (MIT for example:   http://appinventor.mit.edu/explore/stories/my-droid-robot-controlled-app-inventor.html)

Not saying this is the best way, its just a possibility.

Hey Learning can you post a pic of your Uno??  I am curious if it has the other 'features' of a fake arduino such as the chip markings sanded down.

You should return it to CE-Compass.  They have a 30 day return policy and a 15% re-stocking fee but if you prove it is a knock-off I think they might wave that (assuming they are reputable).   If you decide to return it let us know the outcome.

Well, excuse me for posting.

My post wasn't directed at you.  Don't take it personal.  It's just if you have red led's you more than likely got a knockoff Arduino.

I'm all for Arduino clones... just not ones posing as "official Arduino".

Red LED's did you say??   Play "Spot the Fakes" at Spotting Arduino Clones http://www.cmiyc.com/blog/2011/12/26/spotting-arduino-clones/

Here's a hint:

26  Using Arduino / Programming Questions / Re: What is the Best and Free C++ Compiler for Windows(Among other Questions) on: February 08, 2013, 06:53:16 pm

Otherwise,  I would suggest Visual Studio,  for which there is a free version,  or at least there
was about a year ago when I installed it.

It's still free but after 30 days you have to register for a license ID.  It is not bad and the VS2012 has part of C++11 implemented.
27  Using Arduino / Programming Questions / Re: SumoBot help on: February 08, 2013, 06:15:53 pm
I have no clue because you did not post code.   However if you want to get the Ping sensor to work there is an example code that comes along with the IDE for that.

In the Arduino IDE menu click File -> Examples -> 06.Sensors -> Ping.

This code assumes your Ping sensor is hooked up to digital pin 7.  If it isn't then scroll to the line that says:  const int pingPin = 7;

Change the 7 to be the digital pin you connect the Ping sensor to.

As for the code for the Arduino Motor controller look at this tutorial:  http://www.instructables.com/id/Arduino-Motor-Shield-Tutorial/?ALLSTEPS

For an additional output use a GSM shield and send out SMS text  http://labs.arduino.cc/GPRS/Index

For additional inputs did you try looking into some of these   http://en.wikipedia.org/wiki/Burglar_alarm#Sensor_types
29  Using Arduino / Programming Questions / Re: Xbee Communication on: February 08, 2013, 05:58:37 pm
So if i understand you, in the serial monitor i can send message to another xbee and he can understand that message, exemple if i send to serial monitor " analogWrite(3, HIGH); ", he will put +5v to the 3 pin

No.  The Arduino receiving the message has to parse the character stream coming through the Xbee and then act appropriately.  Sending an actual Arduino function call within a string will not automatically call that function.   You are just sending bytes over the Xbees, that is it.

You know a good way to learn this is to Google  "xbee arduino tutorial".   There are many to choose from to help you understand this.

Another good place to look is chapter 14 of the book "Arduino Cookbook".  Great explanations and good sample code.

It doesn't come with a compiler... you need a third-party compiler... hence my question...

Yes... but read the release notes:

    NetBeans C/C++ pack has been tested with the following compilers and tools (Windows):
        Cygwin 1.5.21
        Cygwin gcc-core (C compiler) 3.4.x
        Cygwin gcc-c++ (C++ compiler) 3.4.x
        Cygwin gdb (GNU Debugger) 6.5.50
