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 and fill the board profile. 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.

Project Assembly Workflow

• Requirements Gathering - Analyze user request and gather project specifications
• Architecture Design - Design component connections, data flow, and state machines
• Code Assembly - Combine patterns and customize for user hardware
• Testing & Validation - Verify compilation, memory usage, and functionality
• Documentation - Create wiring diagrams, usage instructions, and troubleshooting guides

Quality Standards & Rules

• Quality Standards - Hardware abstraction, non-blocking code, error handling, and memory safety requirements
• Integration Checklist - Pre-delivery verification for sensor validation, timing, and reliability
• Board Considerations - UNO, ESP32, and RP2040 specific optimizations and constraints

Project Output Template

• Output Template - Standardized format for delivering complete Arduino projects

Resources

• examples/ - Complete project examples with full implementations
• scripts/scaffold_project.py - CLI tool for project scaffolding with config.h, main.ino, platformio.ini, README
• assets/workflow.mmd - Mermaid diagram of project assembly workflow
• workflow/ - Step-by-step project assembly process
• rules/ - Quality standards and board-specific optimizations
• templates/ - Project output templates and documentation standards

Shared Output Contract

Use the shared Arduino skill contract: state assumptions, required tools and versions, implementation steps, tests/evidence by proof stage, known limitations, and recovery/security notes.
