I want to control a button from the website

Hi, all Im new to this forum and arduino, but I want to try some experiment - Lets say I would have a light switch that I want to turn on and off. Would it be possible to build an online interface that does that - I know flash, html and php. So is there a way to accomplish this using arduino? Would it be possible to create a User interface for being used online?

Thank you

Look at your Arduino. Do you see a place to plug a network cable in? If not, you need an ethernet shield.

Once you have one (and don't go cheap, trust me), what you want to do is possible.

Please publish the URL when you are done, so we can turn your lights on and off at all hours of the day and night.

You could also run a server on your pc and use the arduino as the control interface on the pc serial port.
