A single front door for the v2.0 Arduino modernization work, so it's easy to pick back up. Status as of 2026-06-26 .
⏭️ Immediate next action
Merge PR #15 (sketch-board-targeting). It is green on all 4 board jobs and mergeable . It:
assigns the correct board per sketch via sketch.yaml (closes Assign correct board per sketch via sketch.yaml #11
adds compile-CI matrix jobs for AVR/Leonardo/SAMD/nRF52,
marks the i2s-mic+mp3 sketch legacy, and
comments each sketch.yaml + documents the convention in CLAUDE.md.
Open decision before merging: merge as-is, or first fold in #16 (grow CI coverage) so it lands as one "board targeting + coverage" change. Either is fine — #16 is comfortably its own PR. Default recommendation: merge #15 now, do #16 separately.
🔭 Backlog, in suggested priority order
Grow compile-CI coverage to remaining green sketches + untracked boards #16 Assign correct board per sketch via sketch.yaml; gate in CI (#11) #15 arduino-cli sweep, add the green ones to the Uno job.Triage & migrate ESP32 sketches for Arduino core v3.x (lesson-aware) #12 Tone32.hpp → native tone() migration. Check the physcomp lesson before migrating vs. marking legacy. v2.0: fundamental review of all sketch code + comments #13 Update the headers to each .ino to reference textbook, as relevant #9 .ino headers to reference the textbook. Overlaps v2.0: fundamental review of all sketch code + comments #13 — decide whether to fold Update the headers to each .ino to reference textbook, as relevant #9 v2.0: fundamental review of all sketch code + comments #13 CI link-check for textbook lesson URLs in sketch headers #14 AnalogGraphMultipleInputs.ino - e-Ink port #7

Sketch-header template: docs/sketch-header-template.md; compile-checked copy in templates/SketchTemplate/.
Legacy policy: banner in .ino + list in docs/legacy-sketches.md + skip in CI. Check the lesson before deciding migrate-vs-legacy.
CI gotcha: arduino/compile-sketches does not read sketch.yaml — mixed-board folders must be listed per-sketch under the right matrix job.
