As my first Arduino project I wanted to make something impressive but not too challenging. I entered a Christmas Hack with this project and won it! People love Christmas lights.
By the end of this you will have a set of christmas fairy lights that flash in time to jingle bells as can be seen in the attached video. Feel free to modify it and make it your own once you have completed these steps.
During this tutorial I have provided serveral links to Arduino's own tutorials and more about Arduino can be found here
No soldering required.Hovering over the image squares gives you more information.
