arduino-cli

What This Skill Does

The arduino-cli skill enables seamless integration between OpenClaw and the Arduino Command Line Interface. It empowers developers to manage the entire lifecycle of embedded projects directly from their agent interface. The skill handles complex platform management tasks, including core installations, library dependency resolution, board discovery, and code compilation. By abstracting the command-line intricacies, it allows users to focus on hardware logic rather than path configuration or toolchain setup.

Installation

To integrate this skill into your OpenClaw agent, use the command: clawhub install openclaw/skills/skills/547895019/arduino-cli. Ensure you have the official Arduino CLI binary installed on your system PATH before triggering the skill, as the agent acts as an interface layer over the existing local installation. Once installed, verify your configuration by running arduino-cli config init to set up your local workspace.

Use Cases

This skill is designed for IoT development, rapid prototyping, and automated firmware testing. It is perfect for developers needing to compile multiple sketches across various board architectures, manage library dependencies for collaborative projects, or automate the flashing of firmware to connected hardware. It is particularly useful when working with headless environments or remote servers where traditional GUI-based IDEs are impractical.

Example Prompts

1. "arduino-cli: list all connected boards and show me their FQBN strings so I can prepare for compilation."
2. "Can you help me install the ESP8266 board core and make sure all necessary libraries for my sensors are up to date?"
3. "Please compile my sketch 'LightController' for the MKR1000 and upload it to the available serial port."

Tips & Limitations

Always run arduino-cli core update-index after adding new board URLs to ensure the agent recognizes the latest hardware definitions. When working with 3rd party boards like ESP8266 or ESP32, remember that you must explicitly pass the --additional-urls flag unless you have pre-configured them in your arduino-cli.yaml. Note that this skill requires physical access to the device port for uploads; if using a virtualized environment or Docker, ensure you have correctly mapped your USB device path (e.g., /dev/ttyUSB0) to the container. The agent relies on the host's existing arduino-cli installation, so ensure your user account has sufficient permissions to access hardware serial ports.
