Build complete Arduino and embedded projects across Arduino IDE, Arduino CLI, PlatformIO, and vendor-specific toolchains. Use when users request an application combining firmware, sensors, actuators, networking, power, or deployment rather than a code snippet. The bundled scaffold targets UNO, ESP32

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: Create a complete project: Interactive mode: 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.
