Processing with maths and physics

Processing with maths and physics · Course page

Turn raw numbers into physical quantities (tilt angle, energy, altitude, dBFS), derived values like dew point and heat index, and classify with rules before reaching for ML.

Module goal

Use maths and physics to give numbers meaning, and know when a plain rule is enough.

Lessons

Lesson	Topic	Time (min)	Slides
3.1	From raw numbers to physical quantities: tilt angle, energy, altitude and dBFS	65	slides.md
3.2	Hands-on: four physics gauges on screen	75	slides.md
3.3	Derived values and rule-based classification: dew point, heat index and a rule ladder	60	slides.md
3.4	Hands-on: a rule-based comfort classifier	75	slides.md

Lessons come in pairs: a concept lesson followed by a hands-on lesson with a practice file, a solution, and a lab.

Module checkpoint

You pass this module once you can do all of the following (details are in the Lab section of each hands-on lesson):

• A raw signal → a computed quantity → shown on screen, the full loop working for at least one quantity (lesson 3.2).
• Write your own classify() with a rule ladder, and have the board or emulator show a class that genuinely changes as temperature or humidity changes (lesson 3.4).
