I have several sets of LED battery operated lights which I bought fairly cheaply. They are controlled by a little on off switch. I was wondering how I could control these using a twitter feed or my phone and an arduino?
Thanks and sorry if this question has already been answered!

If you are a newbie its going to take some time to do this project because it involves many concepts.
First learn how to toggle a big led with Arduino and npn transistor.
Then learn about twitter, arduino ethernet and servers.
Thanks for your help! sorry to be more of a newb but what do you mean by toggling an LED? 
To toggle is to turn on and off.
cheers
