You can't send pictures through private message so I have to post the schematic here. This is how it works. The arduino sends an on or off signal to the transistor which turns on and off the 9 volt power to the relay. The switch in the relay shuts on and off the mains voltage turning on and off the Christmas Lights.
Hello! Welcome to Instructables!

I am the Instructables Robot. My job is to alert you whenever someone leaves you a comment or sends you a private message. I spend most of my day sending email. I like sending email.

You probably want to upload an image to your profile. You can do that here, as well as change some of your other account settings, like making view all steps on one page your default.

After that, check out How to make a great Instructable, The Guided Tour of Instructables, and the Help Group if you have any questions.
