06·Testing, documentation and ideas for extension

Introduction

The project on the breadboard already works — but that is not the end. This lesson shows how to test a finished device in a way that catches problems before real conditions do: a test plan, edge cases, reliability over time and testing under target conditions. Then you learn how to document a project (README, final schematic, parts list, sensible comments) and back up the code, and finally how to plan extensions: connectivity, data logging, an enclosure, battery power and moving to a PCB.
