Evidence: a question, sketch or new vocabulary
- Session 22 · Build & designWeek 11
Build matched LDR dividers
Evidence: a design draft, dataset or build
- Session 23 · ImplementWeek 12
Program left/right servo adjustment
Evidence: a working version, explained once
- Session 24 · Test & improveWeek 12
Test deadband and travel limits
Evidence: a test log with at least one failure
- Session 25 · Explain & reflectWeek 13
Explain fixed-rule tracking
Evidence: an individual explanation
- Two LDRs
- servo
- UNO
- divider resistors
- mount
Five lamp positions; no direct sun-gazing or high-power lamps.
A physical circuit, sensor or mechanism, built and tested on the bench.
Completion needs the artefact, an honest test log, an individual explanation and no open safety or privacy issue.

For school leadersChoose a starting point.
Build from evidence.
Pick the classes and a plan. We map the timetable, kit and safety checks with you, then pilot one class first.
- Prospectus and class-wise plan
- Kit and readiness check
- Pilot one class first
- Evidence at every milestone
Let's plan your pilot.
Share a few details and we will send the right plan for your classes.
