DIY Microcontroller Projects for Hobbyists

By: Miguel Angel Garcia-Ruiz, Pedro Cesar Santana Mancilla

Overview of this book

We live in a world surrounded by electronic devices, and microcontrollers are the brains of these devices. Microcontroller programming is an essential skill in the era of the Internet of Things (IoT), and this book helps you to get up to speed with it by working through projects for designing and developing embedded apps with microcontroller boards. DIY Microcontroller Projects for Hobbyists are filled with microcontroller programming C and C++ language constructs. You'll discover how to use the Blue Pill (containing a type of STM32 microcontroller) and Curiosity Nano (containing a type of PIC microcontroller) boards for executing your projects as PIC is a beginner-level board and STM-32 is an ARM Cortex-based board. Later, you'll explore the fundamentals of digital electronics and microcontroller board programming. The book uses examples such as measuring humidity and temperature in an environment to help you gain hands-on project experience. You'll build on your knowledge as you create IoT projects by applying more complex sensors. Finally, you'll find out how to plan for a microcontroller-based project and troubleshoot it. By the end of this book, you'll have developed a firm foundation in electronics and practical PIC and STM32 microcontroller programming and interfacing, adding valuable skills to your professional portfolio.

Connecting an LED to a microcontroller board port and using an internal pull-up resistor

In this section, you will learn how to connect a push button to both the Blue Pill and the Curiosity Nano boards. This is a simple exercise for these microcontroller boards, and it demonstrates how to use a push button to send a logical LOW level signal to a microcontroller board to turn an LED connected to it on or off. If we want to use a push button in our electronic circuit example, we will need to connect it to an input port from a microcontroller board. Also, remember that we should debounce our push button to avoid undesirable results.

The following subsection will show you how to debounce a push button that is connected to the Blue Pill via coding. This is the simplest way to debounce a push button and you can use this method in other chapters of this book.
