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:
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!
