Generate Arduino and embedded C++ snippets for sensors, actuators, buses, state machines, timing, data logging, and hardware abstraction. Use when a user requests implementation code and provide the exact board, framework, toolchain, pins, voltage, memory, and library versions first. Bundled templat

Arduino Code Generator Generate production quality Arduino code snippets for sensors, actuators, communication, and embedded patterns. Quick Start Browse example sketches: List available patterns: Generate code for specific pattern and board: Interactive mode: Target Gate Read [the shared contract](../../docs/arduino skill contract.md) 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.
