Now a Netflix film starring and directed by Chiwetel Ejiofor, this is a gripping memoir of survival and perseverance about the heroic young inventor who brought electricity to his Malawian village. When a terrible drought struck William Kamkwamba's tiny village in Malawi, his family lost all of the season's crops, leaving them with nothing to eat and nothing to sell. William began to explore science books in his village library, looking for a solution. There, he came up with the idea that would change his family's life forever: he could build a windmill. Made out of scrap metal and old bicycle parts, William's windmill brought electricity to his home and helped his family pump the water they needed to farm the land. Retold for a younger audience, this exciting memoir shows how, even in a desperate situation, one boy's brilliant idea can light up the world. Complete with photographs, illustrations, and an epilogue that will bring readers up to date on William's story, this is the perfect edition to read and share with the whole family. Read more

In this book, we will work together step-by-step to create five exciting and great projects using the Arduino Uno microcontroller. We will use Autodesk's free Tinkercad software and its block-based programming approach. We will also use sensors in each of the projects, such as a temperature sensor or an ultrasound sensor and many more components.I am an engineer (M.Eng.) and would like to introduce you to the topics of electronics, Arduino, and block-based programming with Tinkercad. I will try to do this in an application-oriented, playful, and simple way using DIY projects. In the first chapters of this book, you will find a short theoretical introduction or a refresher – depending on your level of knowledge – about the Arduino, Tinkercad and electronics in general. In the following chapters, you will find five exciting projects that we will build together step by step. For each project, you'll learn about the components you'll need, how to build the circuit, and how to create the code using block-based programming.No matter what age you are, whether you are still in school, whether you are already an adult, whether you are a student or a retiree, if you are interested in any of these topics, this book is for you! This book is intended for both those who have no knowledge and those who already have some basic knowledge in any of the following areas: Arduino, Tinkercad and Electronics.Take a look inside now and get your copy as an ebook or paperback!

Attention: This book is a sequel to the book "Arduino Projects with Tinkercad" as well as to the beginner's book "Arduino Step by Step". This book is aimed at advanced Arduino users and therefore requires some basic knowledge. It is recommended to work through the two books mentioned above before starting with this book.In this book, we will create some quite difficult but awesome projects for the Arduino Uno microcontroller. We'll use Autodesk's free online software Tinkercad to simulate and program the projects – just as we did in the preceding book. In Tinkercad, we will create – together and step by step – the circuit for each project, the block-based programming, and will simulate how it works. In each of the projects we will use sensors, e.g., a force sensor, a tilt sensor, a soil moisture sensor, an ambient light sensor and many more components. In addition, we will integrate actuators (servo motor, piezo …) that will perform a specific programmed action.I am an engineer (M.Eng.) and I want to introduce you to the topics of electronics, Arduino and block-based programming in Tinkercad. I will do this in a hands-on, enjoyable and easily explained way using DIY projects. You will find a very short refresher about the Arduino and Tinkercad (about 5 pages) in the first two chapters. If you need a more detailed introduction, it is recommended to take a look at the previous books in this series. After that, five quite difficult projects follow. We will realize them step by step (components, schematic, wiring, programming) by selecting the required components and creating the circuit and programming.No matter what age you are, whether you are still in school, whether you are already an adult, whether you are a student or a retiree, if you are interested in electronics, Arduino, or Tinkercad, this book is perfect for you! This book is for anyone who already has basic knowledge of using the Arduino and Tinkercad, as well as general basic knowledge of electronics. So, this book is for advanced users.Take a look inside now and get your copy as ebook or paperback! Read more

The spellbinding true account of the scientific competition to light the world with electricity.In the mid-to-late-nineteenth century, a burgeoning science called electricity promised to shine new light on a rousing nation. Inventive and ambitious minds were hard at work. Soon that spark was fanned, and a fiery war was under way to be the first to light―and run―the world with electricity. Thomas Alva Edison, the inventor of direct current (DC), engaged in a brutal battle with Nikola Tesla and George Westinghouse, the inventors of alternating current (AC). There would be no ties in this race―only a winner and a loser. The prize: a nationwide monopoly in electric current. Brimming with action, suspense, and rich historical and biographical information about these brilliant inventors, here is the rousing account of one of the world’s defining scientific competitions.
