Hi Sang,

I understand that you want to send the data from MATLAB to Aurdino, you can use the 'serialport' function.

Follow the steps below for data transfer:

1. Ensure that your Arduino is connected to your computer.
2. Determine the COM port to which your Arduino is connected.
3. Use the 'serialport' function in MATLAB to send data to the Arduino.

Sample Code:

comPort = 'COM4';  % COM port
baudRate = 9600;   % match the baud rate set in your Arduino sketch
arduinoObj = serialport(comPort, baudRate);

dataString = 'Hello, Arduino!';

% Send the data string to Arduino
write(arduinoObj, dataString, "string");
%clear arduinoObj;

Refer the below documentation link for better understanding:

Hope it helps!
