I recently bought an arduino and this is the first project that I have (successfully) completed. This is a super easy project and it's mostly to get beginners to understand how arduinos work. I found this project in a book called "30 Arduino Projects for the Evil Genuis". It's a great book and it's very easy to understand! I hope every body enjoys this instructable! The book is slightly outdated so but I can still understand how to do everything. This instructable does the same thing that the book does but explains it in a way that is up to date. Enjoy!

If you use pin 13, you don't need the resistor. Pin 13 has a resistor soldered on the arduino (100 ohm as far as i know). That's why the default blink application uses pin 13.

Nice instructable!
I should look at the examples included on the arduino software - I never have tried them.
