Hello everyone! Today we will explore the Arduino Yún and connect it to a local network. This board combines familiar Arduino programming with an onboard Linux system, allowing a project to read physical inputs and communicate with network services without keeping a desktop computer attached. We will start by understanding its two processors, then follow the original illustrated Wi-Fi configuration procedure. After that, we will upload a simple sketch, distinguish USB communication from Bridge communication, and plan a small sensor-logging application. This tutorial concerns the original Arduino Yún, a legacy board. Its screenshots show the original configuration interface, so menu details can differ with the installed Linux image and development tools. Identify your board revision before ...
