Learning about microcontrollers? Want to avoid the mistakes that I made along my learning journey? All the tips and tricks that will help you advance your skills, demonstrated using a Raspberry Pi Pico. If you've heard about the Raspberry Pi Pico you may know that it provides a fantastic method to learn about using a microcontroller and to develop some skills that go beyond the basics. This will be a journey of discovery for both of us. By experimenting with microcontrollers we will be learning about interfacing from the computing world to the physical world. There’s a lot of information in the book. There’s ‘stuff’ that people with a reasonable understanding of microcontrollers and programming will find excessive. Sorry about that. I have gathered a lot of the content from other books I’ve written to create this guide. As a result, it is as full of usable information as possible to help people who could be using the Pico and coding for the first time. MicroPython is a programming language that is an implementation of the core of Python 3 and includes a small subset of the Python standard library. The simplicity of the Python programming language makes it an excellent choice for beginners who are new to programming and hardware. However, in spite of its name, MicroPython is reasonably full-featured and supports most of Python’s syntax so if you’re comfortable with Python you will be in familiar territory.
