Into The Wild: Group Project Kickoff ¶

With a basic understanding of code structuring (classes and modules - and TDD), let’s hack something. Idea: a “data logger” application.

Configurable set of sensors
Polymorphic data sinks
Acquisition engine in the middle
CSV log format initially; if there’s time, we could add more (XML? MQTT?)

Spoiler: Group Project Outcome ¶

This is what became of it, at the end of day 3:

A set of sensors, arranged in a class hierarchy
A set of data loggers, arranged in a class hierarchy
A set of error handlers, arranged in a class hierarchy
An acquisition loop class which uses sensors, loggers, and error handlers
