What is argus?

Argus is a small service designed to run on a Raspberry Pi and handle hardware control tasks. Think of it as a bridge between your Raspberry Pi and your software, it lets you control physical devices (like lights, motors, or sensors connected to the Pi's GPIO pins) through code. The project is built in Java and requires Java 17 to run. It also depends on Pi4j, a library that gives Java programs the ability to interact with a Raspberry Pi's GPIO pins (the connectors where you plug in hardware). The README includes setup instructions for getting both of these dependencies installed and working on a 32-bit Raspberry Pi system. Once installed, Argus runs as a system service, meaning it starts automatically when your Pi boots up, and you can manage it like any other background process on Linux. The installation involves copying a service configuration file and enabling it through systemd (the system that manages background services on Linux). The name "Argus" and the "Justin dev-ops stuffs" label suggest this is a personal or team project rather than a general-purpose tool. It's the kind of microservice you'd build if you wanted a reliable, always-on way to integrate a Raspberry Pi into a larger system, perhaps monitoring sensors, controlling home automation hardware, or managing IoT devices. The README is minimal, so the specific functionality isn't detailed, but the foundation is there for running Java-based automation tasks on a Raspberry Pi.
