Lamp 220 Volt control

Hi all,

I’m trying to make a circuit to control a lamp (220V) does anyone have experience with this?
What are the options? does anyone know a transistor or something that can do this?

Have a look at this link:

Do a search of the forums (and google) for "BT138".

The BT138 is a TRIAC right? Don't i need some kind of DIAC for controlling the TRIAC? And the datasheet is telling that the gate trigger current is 12V; 0.1A my Arduino can't provide those 12V,0.1A?

Look at this thread http://arduino.cc/forum/index.php/topic,92181.0.html. It doesn't get much simpler than using a solid state relay.
