Chat With Arduino

Use Claude or other LLMs to control your Arduino microcontroller!

How it works

[demo goes here]

Features

• Control your Arduino directly through Claude
• no code writing or uploading required. Claude handles it all
• You can move motors, turn on LEDs, read sensors directly via Claude
• Claude can write it's own code and upload it to the microcontroller

Installation

Install the desktop-based LLM app. I'll show how to use Claude Desktop, but you can also use ollama paired with oterm for fully local tool-use.

1. Install Claude Desktop either from the website or via brew install --cask claude

2. Install uv: curl -LsSf https://astral.sh/uv/install.sh | sh

3. Tell Claude how to use Chat With Arduino:

   echo '{
   "mcpServers": {
       "chat-with-arduino": {
         "command": "/opt/homebrew/bin/uvx",
         "args": [ "beyarkay/chat-with-arduino" ]
       }
   }
   }' > ~/Library/Application\ Support/Claude/claude_desktop_config.json
   

Now open Claude Desktop, and you should see a small hammer icon on the bottom right of the chat window:

You are now good to go! Claude is smart enough to figure out what commands need to be called to do what you want it to.

Usage

Roadmap

• Auto-install arduino-cli
• Support for ESP32
