Set Up Arduino Board in MATLAB

Set Up Arduino Board in MATLAB

Guides the agent through discovering, configuring, and connecting to Arduino boards via USB, ensuring the user is informed and in control at each step.

When to Use

• User wants to connect to an Arduino board from MATLAB
• User asks to discover or list connected Arduino boards
• User's task requires an Arduino connection as a prerequisite (reading sensors, controlling actuators, scanning I2C, etc.)
• User mentions Arduino, COM port, serial port, or hardware setup

When NOT to Use

• Creating custom addon libraries for unsupported peripherals (see matlab-create-custom-arduino-library)
• Bluetooth or WiFi Arduino connections (not covered here)
• Arduino IDE or support package installation issues
• Simulink hardware-in-the-loop workflows
• Tasks that already have an active arduino object in the workspace

Workflow

Follow these steps in order. Do not skip steps or guess values.

Core principle: Never assume. Always ask the user before proceeding if any information is unclear or ambiguous.

Step 1: Discover boards

Always run both commands — do not skip serialportlist even if arduinolist already found the board. This is a hard requirement:

list = arduinolist
ports = serialportlist("available")

Both calls are mandatory. Never omit serialportlist — arduinolist alone misses boards without support package firmware.
