Real-time web control for light decorations (no server side coding)

Arduino Ethernet is an awesome device. This is how to operate your festive seasonal lights from wherever you want:
-by a simple click on your web-page (a few lines of HTML, no javascript, or any other coding is required);
-by entering a simple "http://..." line into any browser on any device like a phone, a computer, or a tablet
-from any other internet enabled device such as another Arduino Ethernet.

Step 1 Gathering details and preparation

The solution utilises a cloud-based real time web publishing tool Partcl.com  that allows you to publish any data with about 0.1 second latency.
First you will need:

-  Arduino Ethernet (which is in fact is Arduino + Ethernet Shield)
-   NPN transistor, like BC548
- 5.6 kOhm resistor
- wires
- ethernet cable
-power adaptor for Arduino
- Free account on Partcl.com (when registered you will get your publishing and web keys which you will put into Arduino code and in http code on your website)
- seasonal lights themselves (I used what I had, small 100mA chain of leds) - you may need to add an additional resistor for different "led architecture", or even use a relay to power some major decoration )) - up to you.
As a holder for LEDs I used something that was called "Tree" in a  shop. I thought it would look cool.

Cool. Do the same thing with old pc;s all the time.
