Project description

A reusable Arduino communication framework that connects physical cockpit controls (switches, rotary encoders, potentiometers) to the X-Plane flight simulator over UDP, using an Arduino Ethernet Shield (W5500). 1. The Problem X-Plane isn't a typical flight game — it models aircraft systems in professional-grade detail and exposes two things over the network for external hardware to interact with: Commands — trigger simulator actions (landing gear, autopilot functions, etc.) DataRefs — represent internal simulator variables (airspeed, altitude, switch states, etc.) The catch: every new…
