Creative DIY Microcontroller Projects with TinyGo and WebAssembly

By: Tobias Theel

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.

Building a home automation dashboard

After you have finished this book, you might want to build lots of cool projects that could include LED stripes or a motion-sensor-controlled light, or you might add a motor to your curtains to open or close them based on the light intensity or the time. These would be really cool projects, but now imagine that you're sitting on the couch and want to watch a movie, but the sun is too bright and did not exceed the threshold to start the motor that controls the curtains. What can we do in such a situation? Do we stand up and close the curtains manually, or do we open a Wasm app on our smartphone or tablet in order to control the motor for the curtains by just pressing a button on an app? You might also want to check if the LED stripe in the living room is still turned on, but you do not want to get out of bed to check. In that case, it would be great to have a dashboard that informs you about its status. In this section, we are going to build...
