Arduino in a Nutshell

Downloaded over 70,000 times!

The Arduino is a family of microcontroller boards to simplify electronic design, prototyping and experimenting for artists, hackers, hobbyists, but also many professionals.

This little booklet, written by Prof. Jan Borchers, introduces you to using an Arduino. It covers the latest beginner-friendly board, the Arduino Uno R3, and the latest version of the Arduino IDE, 1.0.5. It comes with shopping tips and a SparkFun online wish list to get the parts you'll need.

Book size is 8 x 6 inches. Print at original size (100% scale!) onto larger paper and cut to size outside the cropmarks on the cover. The size is also perfect for reading on an iPad.

The latest version is 1.8, from August 5, 2013. See the last page in the book for a version history.

About this booklet

I've taught Arduino in class for a few years now, mostly to CS students, and just the other day introduced two friends to it again. Being on sabbatical and all, I couldn't keep myself from just writing through the rest of that night and adding some Fritzing diagrams the next morning, and the result was a short little booklet introducing Arduino basics. I've since debugged it and added a bit more polish.

Yet another one, you say? Yes - the Arduino boards and IDE change so frequently that first-step tutorials and books are bound to become outdated after just a few months. I wanted something that got people started with the latest stable "beginner's" board and IDE. I plan to update it as new boards and IDE versions come out, but I'll keep older versions online too, so you can use them if you start out with an older board.

I'm forcing myself to keep it to one book page per experiment wherever possible - as I add information, I tighten up my writing to stay within that limit. Helps keep me from rambling on.

I also wanted to capture the fun of our hands-on learning session, with very little overhead. It's written for people who've done a bit of programming at some point in their lives, but are new to electronics, and all experiments together can be completed in a long-ish night.

Finally, I wanted something that doesn't take up your laptop screen while you're working in the Arduino IDE, so it's a PDF you can print, cut and bind into a 8x6" booklet. That also happens to be the screen size of an iPad. :)

Feel free to use this for yourself, with your friends, or in your classes, and let me know how it goes! A request: instead of hosting a local copy of the PDF on your servers, simply link to That way we can make sure everybody always gets the latest version, instead of old copies floating around. I'll archive older versions here too. Thanks!

Version 1.8:
  • In Chapter II ("Getting Started"), Mac OS X 10.10 "Yosemite" users should be warned that they may need to install Java manually, using, e.g., Apple's JRE6 installer.
  • In Chapters VI ("Digital Input") and VII ("Internal Pullup Resistors"), the variable "button" should be called "pushbutton" throughout the code examples.


  • Dr. Gerald Ardito covers Arduino in a Nutshell in his Inventing Learning blog. (Aug 15, 2012)

Teaching with this booklet

The material in this book is based on a (long) evening of introducing some friends with a technical background to Arduino. I used it to teach a 3.5-hour Arduino workshop at UCSD in September 2012, covering everything in the book as of version 1.5. Here's our schedule, which worked out pretty well. At GUI&DESIGN 2014, with a more homogeneous developer audience and 16 boards, we were able to complete all experiments (Chapters I-XI), and briefly touch upon shields (XII) and next steps (XIII), in 2.5 hours.
