Arduino Project Builder
Assemble complete, working Arduino projects from requirements. This skill combines multiple patterns (sensors, actuators, state machines, logging, communication) into cohesive systems.
Quick Start
List available project types:
uv run --no-project scripts/scaffold_project.py --list
Create a complete project:
uv run --no-project scripts/scaffold_project.py --type environmental --board esp32 --name "WeatherStation"
uv run --no-project scripts/scaffold_project.py --type robot --board uno --output ./my-robot
Interactive mode:
uv run --no-project scripts/scaffold_project.py --interactive
Intake And Evidence Boundary
Before assembling a project, read [the shared contract](../../docs/arduino-skill-contract.md) and fill [the board profile](../../docs/board-support/board-profile-template.md). Record the exact board, framework, toolchain, versions, pins, memory, power, protocols, and recovery path. Keep build, upload, hardware, system, and deployment proof separate; a generated scaffold is not hardware validation.
The scaffold script emits its supported board targets and PlatformIO structure. For another board or vendor framework, reuse the requirements and architecture workflow, then provide a toolchain-specific implementation rather than changing the script's claimed support.
