 +===== Overview =====
 +The Yun is a single board computer that combines an Arduino microcontroller with a Linux-based system, allowing for easy internet connectivity and the ability to run complex applications. It features built-in WiFi, supports various programming languages like Python, and is designed for projects that require both hardware control and network capabilities.  It’s useful when a project needs Arduino-style sensor and actuator control alongside Linux networking, scripting, and file handling.
