Raspberry Pi

The Raspberry Pi is a low-cost, credit-card-sized single-board computer that serves as a powerful, accessible tool for learning fundamental computer science concepts and building Internet of Things (IoT) applications. By running a full operating system and providing General-Purpose Input/Output (GPIO) pins, it allows users to write code that directly controls electronic components like sensors, lights, and motors. This unique ability to bridge software with the physical world makes the Raspberry Pi a popular choice as the central 'brain' for prototyping smart devices, enabling it to collect data, process information, and communicate over a network to create interactive, connected systems.
