About Course

This is a live, taught programme — not a pre-recorded course. Over 20 class days you work through 30+ sensors and modules and build 50+ real projects, with the instructor on the other side of the screen (or at your table) the whole way. Every session opens with how the day’s sensor actually works and ends with something running on your bench.

How the course works

Built around real projects, not slides.

1. Concept first
Every session opens with the fundamentals of the day’s sensor — how it works and where it’s used in the real world.
2. Build immediately
Theory is followed straight away by wiring and code, so the learning sticks through doing.
3. One display, mastered
The OLED is taught once and reused in every project, so focus stays on the new sensor each day.
4. Three projects per pair
On two-sensor days you build one project per sensor plus a combined build — three outcomes in a session.

The curriculum — 20 days, 8 phases

Duration key: 2 hrs standard · 2.5–3 hrs two-sensor / three-project days · 3–4 hrs big builds. Each phase is colour-coded by what you are working with.
