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.

Technical requirements

We are going to need the following components for this project:

  • An Arduino UNO
  • Capacitive Soil Moisture Sensor v1.2
  • K-0135 Water Level Sensor
  • Passive buzzer with 2 pins
  • Micro submersible water pump DC 3V-5V
  • Breadboard power supply module
  • Jumper wires
  • One breadboard
  • One 100 Ohm resistor

These components can usually be found in online stores and also in local electronic supply stores. Most components used in this book are also part of so-called Arduino Starter Kits.
