This book is a project-based guide designed to bridge the gap between basic electronics and modern intelligent systems. The Raspberry Pi has transformed physical computing, the Internet of Things (IoT), and edge artificial intelligence by making powerful computing accessible to everyone. Along with the origins, setup, and troubleshooting of the Raspberry Pi, this book guides you through Linux terminal navigation, file management, and beginner-friendly Python programming. Readers learn to configure Raspberry Pi OS and develop essential Linux command-line skills for working with Raspberry Pi-based systems. You will also learn Python programming for hardware automation and device control. With these fundamentals in place, the focus shifts to hardware interfacing. You will learn to interface with real-world sensors such as the BME280 for environmental monitoring, ultrasonic sensors for distance measurement, and LDRs for light detection
