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.

Your first project – a blinking LED

This small project demonstrates how to connect an LED to a microcontroller board and how to program one of their I/O ports so that you can turn the LED on, wait for 1 second (1,000 milliseconds), turn the LED off, wait another second, and turn the LED on, in an endless loop.

The project also demonstrates how to upload a compiled program to a microcontroller board. This is an important starter project, since you can later reuse this code for sending a signal to a port and controlling a more complex application, such as a fan. This is like a Hello World project for microcontroller boards! We will run this project for both the Blue Pill and the Curiosity Nano microcontroller boards using their respective IDEs.

Running the blinking LED example with the Blue Pill board

This small project demonstrates how to turn an LED on for 1 second, and then off for 1 second, repeatedly. Of course, it also demonstrates how to declare and use an I...
