Materials and Help to build a Domotic project

Hi. I want to do a domotic house model built with Arduino and controlled by Internet. But I have no knowledge about it, so I need your help. What materials should I buy? (sensors, Arduino, etc.)(All will be simulated by LEDs)? And what do you recommend to start learning Arduino?

Thank you!

Well, the first thing you will need is knowledge. Several cartons of knowledge. Then, you'll need some more.

Next, you'll need some requirements. Without those two items, your project is a non-starter.

If you don't know what you want to do, you won't know what you need to accomplish the requirements.

A quick peak at the forum topics reveals that there is a category for Home Automation and Networked Objects. Spending some time lurking there would be useful.
