From the project
Im Schuljahr 2025/2026 wurde im Rahmen der Ausbildung zum staatlich geprüften Techniker diese Technikerarbeit in Zusammenarbeit mit der Gottlieb Daimler Schule 2 in Sindelfingen sowie der SOTEC GmbH & Co KG in Ostelsheim erstellt.
Der Hardware Prüfadapter ist ein Embedded-System auf Basis eines ESP32-S3, das entwickelt wurde, um externe Hardwarekomponenten und Baugruppen automatisiert zu testen und zu simulieren. Das System stellt eine Brücke zwischen analoger/digitaler Hardware und modernen Web-Technologien dar.
Das Hauptaugenmerk der Entwicklung lag auf einer sauberen Systemarchitektur (Clean Architecture), extremer Ausfallsicherheit (Fail-Safe-Mechanismen) und einer hohen Testabdeckung durch systemunabhängiges Unit-Testing (TDD).
