Create an Arduino object using arduino before you use read and write functions. See Connect to Arduino Hardware for more information. You can also use Arduino Explorer app to configure each pin of the Arduino to read and write data.

You can use the MATLAB Function block to generate readable, efficient, and compact C/C++ code that can be deployed to the Arduino hardware. For a detailed overview of the MATLAB Function block, see Implement MATLAB Functions in …

Use the arduino function to connect Arduino or Arduino-compatible ESP32 hardware to MATLAB ®. After you create the object, you can program your hardware and use custom add-on libraries directly from MATLAB using the Object Functions .

This example shows how to use MATLAB® Support Package for Arduino® Hardware to perform basic operations on the hardware such as turning an LED on and off, blinking LEDs and playing sound on a speaker.

MATLAB ® Support Package for Arduino Hardware enables you to use MATLAB to communicate with several Arduino boards under the entry-level series, MKR, and Nano families of Arduino. You can read and write sensor data through the Arduino and immediately see the results in MATLAB without having to compile.

[dataOut,payloadSize] = sendCommand(arduinoObj,libName,commandID,dataIn,timeout) sends a command to the Command Handler implemented by your add-on library with a user-specified acknowledgment timeout.

Tasks represent a series of MATLAB commands. To see the commands that the task runs, show the generated code. Common tasks available from the Live Editor tab on the desktop toolstrip: • Clean Missing Data • Clean Outlier • Find Change Points • Find Local Extrema

MATLAB Compiler produces an installer that installs the standalone application and all the required dependencies on a target computer. For more details on the application compiler app, see Create Standalone Application from MATLAB Function (MATLAB Compiler) and Manage Support Packages (MATLAB Compiler) .

hwtable = arduinolist returns a table of Arduino ® boards connected via USB. hwtable = arduinolist(Timeout=tlimit) limits the time to wait for hardware queries to tlimit seconds. The default Timeout value is 20 seconds.

This example shows how to connect to Arduino ® or ESP32 hardware in MATLAB ®. Make sure the Arduino or ESP32 hardware is connected to the computer. If the device is unofficial, note the port and the board name.
