Arduino Project Handbook
Arduino Project Handbook

Arduino Project Handbook is a beginner-friendly collection of electronics projects using the low-cost Arduino board. With just a handful of components, an ­Arduino, and a computer, you’ll learn to build and program everything from light shows to arcade games to an ultrasonic security system.

First you’ll get set up with an introduction to the Arduino and valuable advice on tools and components. Then you can work through the book in order or just jump to projects that catch your eye. Each project includes simple instructions, colorful photos and ­circuit diagrams, and all necessary code.

Arduino Project Handbook is a fast and fun way to get started with micro­controllers that’s perfect for beginners, hobbyists, parents, and educators.

Author Bio 

Mark Geddes is a lifelong tinkerer and gadget enthusiast. Frustrated with the lack of practical, visual guides to help him teach his 10-year-old how to build with Arduino, he set out to record his own experiments, and Arduino Project Handbook is the result. Geddes has a bachelor's degree from Edinburgh College of Art. He lives in Dumfries, Scotland.

“This books walks you through not only the simple, beginner’s stuff that everyone does; but also the complex, larger projects that demonstrate the real power of Arduino. These projects will genuinely keep you motivated to continue learning. Having a practical, exciting thing to make is more motivating than simply making a thing for the sake of it.”

“If you are going to start messing around with Arduino projects, this is the book to start with, and it will get you quite far.”
Science Blogs

“This guide is ideal for both beginners and those experienced with electrical systems. Simple diagrams and pictorial guides add to the instruction without overwhelming the reader. Libraries and classrooms interested in creating makerspaces, or those building upon an established collection, would do well to consider purchasing this handbook.”
School Library Journal

Electronics Weekly features the handy plant monitor project that will show you how to set up a light and sound alarm system to tell you when your plants need watering.

“While originally written to teach his child the joys of electronics and experimentation, it is completely relevant for anyone looking to learn how to use the Arduino in the real world.”
Full Circle Magazine

“Overall this is another great Arduino book. Mark Geddes does a great job of showing how new makers can leverage an Arduino. I recommend the Arduino Project Handbook for any aspiring makers and those new to electronics!”
Milluzzi Labs

“It’s a great book for children of ALL Ages (I’m 44) to dive in with some fun projects. Anyone who wants to learn, and wants some “instant gratification” to get those positive reinforcement juices going, this book is for them!”
