Before buy: is it possible to handle a 220V lamp?

I'd like to build this, but i'm not sure if Arduino is able to handle all of this things.

With a remote (the standard VISA 6-button blue remote) I want to command one single 220V lamp.

Key 1; lamp always on Key 2; lamp always off Key 3; lamp on when a movement sensor reactm off after 60 seconds Key 4; lamp on, auto-off after 60 seconds

If I can realize this with Arduino ... tell me where to start and wich component must i buy, other than arduino itself !!!

Thanx from an interested newbie !

Have a read through on this product:

Ok, you linked me a Relay. I know i need this, but ... is it possible to connect this relay DIRECTLY to out pin of Arduino?

And Arduino has got a radio sensor or must I buy the radio receiver for remote ? Which must I buy?

Well the data sheet says the minimum trigger is 10ma, so you should be good. Though, I always like to play it safe and just use a transistor.

And radio sensor? The Arduino doesn't come with a RF receiver, transmitter, or transceiver.

I'm not 100% sure what kind of remote it is, but if it's for a light I would be willing to bet it's an Infrared remote, rather than RF, though I'm more often wrong than right. :)

Yes, the Arduino is capable, using relays, of switching mains voltage devices on and off.

Yes, you can remotely control it using either RF modules or IR sensors.

A nice remote to use:

It costs a lot !

Is there any alternative from ITALY ?

You may want to try one of these: http://www.dealextreme.com/details.dx/sku.27126

The $8.99 price includes shipping to anywhere in the world.

Thanks for reply, but this is a remote for Power Supply only...

I must buy a remote and a radio sensore for arduino.

Perhaps you could hack this one for input to arduino : http://www.dealextreme.com/details.dx/sku.23633 Disconnect the alarm from the receiver and connect the signal to an arduino input pin. Have a search on that site for other remote control options

These items usually have a capability to change codes so the transmitters wont conflict with each other.

This approach will require some electronics tinkering to get it going but has the advantage that you don't need to get near the mains voltage.
