Creative DIY Microcontroller Projects with TinyGo and WebAssembly

Overview of this book

While often considered a fast and compact programming language, Go usually creates large executables that are difficult to run on low-memory or low-powered devices such as microcontrollers or IoT. TinyGo is a new compiler that allows developers to compile their programs for such low-powered devices. As TinyGo supports all the standard features of the Go programming language, you won't have to tweak the code to fit on the microcontroller. This book is a hands-on guide packed full of interesting DIY projects that will show you how to build embedded applications. You will learn how to program sensors and work with microcontrollers such as Arduino UNO and Arduino Nano IoT 33. The chapters that follow will show you how to develop multiple real-world embedded projects using a variety of popular devices such as LEDs, 7-segment displays, and timers. Next, you will progress to build interactive prototypes such as a traffic lights system, touchless hand wash timer, and more. As you advance, you'll create an IoT prototype of a weather alert system and display those alerts on the TinyGo WASM dashboard. Finally, you will build a home automation project that displays stats on the TinyGo WASM dashboard. By the end of this microcontroller book, you will be equipped with the skills you need to build real-world embedded projects using the power of TinyGo.

Chapter 1: Getting Started with TinyGo

In my opinion, Go is easy to learn, easy to read, and easy to write. The language is not overloaded with fancy features but rather focuses on being concise. The built-in concurrency, fast compile times, high execution performance, and rich standard libraries make a great mix for an awesome language. This is why I want to take you on a journey from very basic high-level Go programs to the depths of microcontrollers utilizing the full power of TinyGo.

In this chapter, we are going to set up TinyGo and learn how to get code completion to work in VS Code and different editors. After this is done, we will have a look at the Arduino UNO and its technical specifications. We are going to compare TinyGo with Go and talk about what makes TinyGo special compared to other languages on microcontrollers. At the end of this chapter, we will write, compile, deploy, and run our first TinyGo program on a real microcontroller. Having all these topics covered...
