To Jean White, my mom.

Audrey O'Shea is a New York State licensed technical instructor teaching electronics and CompTIA certification courses at a technical high school. She also has taught college-level IT courses, holds numerous industry certifications, and has been a mentor to teachers who are new to the profession. Prior to beginning her teaching career, she served as CEO of a consulting company that provided computer training, along with custom software and network installation and support.

O'Shea has degrees in accounting and information technology as well as her teaching license, and she is a member of the Phi Kappa Phi honor society, a public speaker, and a proponent of encouraging women to set their sights on STEAM careers. She has written two books in the self-help genre and served as technical editor on another technology book. In her spare time she enjoys hiking and kayaking in the Adirondack Mountains of New York State, gaming, building and fixing things, and automating her home.

Mike Hitsman is a mechanical engineer working for a small construction company in Central New York. It affords him the luxury to pursue machining, welding, electrical diagnostics, and programming as needed day to day. He attributes his technical breadth to FIRST Robotics, where he started as a student and now mentors the local team. His knowledge of electronics is entirely self-taught, through lots of reading, lots of trial, and lots of errors.

Hitsman lives with Audrey O'Shea's daughter at their country homestead, where he is slowly adding more and more automation to the old farmhouse. He's as likely to be tweaking an IoT device as he is repairing something from 100 years ago.

I would like to shower praise on the people who have helped me provide this book for your amusement and education. First, Kenyon Brown for giving me the opportunity. Next, Jan Lynn, my project editor, for pushing me to get it done. Also, a big thank-you to Michael Hitsman, my technical editor, for his polite and concise suggestions on how to make it better. I would be remiss if I failed to mention my friend and fellow author, Mike Meyers, who encouraged me to start writing in the first place, and I would not have made it this far without my mom, who always had my back when the world said, You can't, and I said, Yes, I can. Finally, to my family and friends, thank you so much for understanding all the times I said, I'm sorry, I can't. I have a chapter due. Thank you all.

Welcome to the world of electronics! This is an exciting place to be, and I'm so glad that you've decided to join me in this journey. IoT and electronics are inseparable, as you'll soon see. We'll start with learning about electronic components and creating some useful circuits. In addition to traditional electronic circuits on breadboards, many chapters have circuits that use the programming power of an Arduino board. Finally we'll be connecting your circuits to the Internet so you can control them from anywhere. This book starts small and helps you grow in knowledge as it progresses and encourages you to reach even further. My true hope is that it will get you excited about working with electronics, regardless of whether it's a hobby or a new career, and that it will give you confidence to do whatever it is that makes your heart sing, no matter who or where you are in life.
