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.

Finding drivers for TinyGo

As of the time of writing, there are 53 devices supported by TinyGo. The driver we just wrote, which I am going to contribute to TinyGo, will support 54 devices. But where can we find drivers for devices that we want to use? The answer is simple: there is a repository for this purpose. You can find it at

In the next chapter, we will learn how to use such drivers when using different types of displays.

Contributing drivers to TinyGo

The TinyGo community happily appreciates all contributions. If you develop a driver for a device and want to contribute it to TinyGo, you can follow these simple steps:

  1. Open an issue and explain what you want to add and how you plan to implement it.
  2. Fork the repository.
  3. Create a new branch based on the dev branch.
  4. Create a pull request.

You can find the contribution guidelines at the following link:
