description: Generate Arduino/embedded C++ code snippets and patterns on demand for UNO/ESP32/RP2040. Use when users request Arduino code for sensors, actuators, communication protocols, state machines, non-blocking timers, data logging, or hardware abstraction. Generates production-ready code with proper memory management, timing patterns, and board-specific optimization. Supports DHT22, BME280, buttons, I2C/SPI, EEPROM, SD cards, WiFi, and common peripherals.

# Arduino Code Generator

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

## Quick Start

**Browse example sketches:**
```bash
# 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:**
```bash
uv run --no-project scripts/generate_snippet.py --list
```

**Generate code for specific pattern and board:**
```bash
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:**
```bash
uv run --no-project scripts/generate_snippet.py --interactive
```

## 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
