# Arduino CLI

> Use this tool when you need to automate Arduino development workflows, from dependency management to serial communication, to streamline hardware operations and ensure electrical safety. It solves problems such as manual board and port configuration, sketch compilation, and upload errors, while providing features like automatic detection and preflight checks. The Arduino CLI takes in sketch files and board configurations as inputs and outputs compiled and uploaded code, serial communication data, and safety check results.

## Description

Arduino development automation server that wraps arduino-cli to provide end-to-end hardware workflows from dependency management through serial communication. Features automatic board and port detection with FQBN inference, sketch compilation and upload, stateful serial sessions with pattern matching, and electrical safety preflight checks that verify wiring, voltage limits, and pin capabilities before hardware operations. Includes a curated board reference database covering popular Arduino and ESP32 boards with detailed pinout specifications.
