Arduino Code Generator

Generate production-quality Arduino code snippets for sensors, actuators, communication, and embedded patterns.

Quick Start

Browse example sketches:

# See 9 production-ready examples in examples/ folder
ls examples/
# config-example.ino, filtering-example.ino, buttons-example.ino,
# i2c-example.ino, csv-example.ino, scheduler-example.ino,
# state-machine-example.ino, hardware-detection-example.ino,
# data-logging-example.ino

List available patterns:

uv run --no-project scripts/generate_snippet.py --list

Generate code for specific pattern and board:

uv run --no-project scripts/generate_snippet.py --pattern i2c --board esp32
uv run --no-project scripts/generate_snippet.py --pattern buttons --board uno --output button.ino

Interactive mode:

uv run --no-project scripts/generate_snippet.py --interactive

Target Gate

Read the shared contract and the board profile before selecting pins, APIs, or libraries. Keep board-specific branches isolated, check memory and peripheral constraints, and state whether the result has build proof only or also has upload, hardware, and system proof. The generator's board flag is a template selector, not evidence that the generated code works on a similar-looking board.

Code Generation Workflow

• [ ] [Identify Pattern Type](workflow/step1-identify-pattern.md) - Analyze user request to determine core pattern category
• [ ] [Read Reference Documentation](workflow/step2-read-reference.md) - Consult pattern-specific reference files for implementation details
• [ ] [Generate Code](workflow/step3-generate-code.md) - Create production-ready code following quality standards
• [ ] [Provide Instructions](workflow/step4-provide-instructions.md) - Include wiring diagrams and usage guidance
• [ ] [Mention Integration](workflow/step5-mention-integration.md) - Suggest combinations with other patterns when relevant

Quality Standards & Rules

• [ ] [Quality Standards](rules/quality-standards.md) - Compilation, timing, memory safety, and error handling requirements
• [ ] [Board Optimization](rules/board-optimization.md) - UNO, ESP32, and RP2040 specific optimizations and features
• [ ] [Common Pitfalls](rules/common-pitfalls.md) - Critical mistakes to avoid in Arduino development

Code Output Template

• [ ] [Code Template](templates/code-output-template.md) - Standardized structure for generated Arduino sketches
