Parts list

This book also includes instructions on how to use the Raspberry Pi board, basic Linux commands for handling the Raspberry Pi, and Python coding required for sensor operation.
You can learn the sensor's operating principles and coding methods through various examples, and explanations are included so that even those who are new to Raspberry Pi can easily follow the code.
Having donated my coding talents to the Code Club Korea Committee for many years, I've also incorporated tips into the book that I hope those new to Raspberry Pi will know.
Therefore, it would be a good content for teachers who actually teach Raspberry Pi in the field to use as a teaching material.

- Step-by-step instructions for completing the project by chapter
- Includes various codes (RPi.GPIO code and gpiozero code)
- Composed of content and practice focused on implementing Home IoT
- Includes project video

Clearly, there are more opportunities to learn coding than there were in my childhood, and the world is one where anyone with the passion can create something.
We live in a world where we can easily search the internet for any question we have, anytime, anywhere. However, if we don't set clear goals amidst this deluge of information, we'll find ourselves lost in the sea of ​​information.
This book is intended to serve as a compass for beginners of Raspberry Pi, showing them where to start and what direction to take when they are first starting out and are unsure of their goals.
Finally, I hope that this book will serve as a helpful hint for those who are just starting out with Raspberry Pi and encounter questions or difficult-to-solve problems.
