Hello,

You will need to setup Hardware Support Package for MATLAB.

You can do so in Environment > Add-Ons > Get Hardware Support Packages > MATLAB Support Package for Arduino Hardware.

After installing the support package for MATLAB, we need to check if it has been installed properly or not. You can do so by connecting Arduino to your system and typing the following command in MATLAB command window. If connected successfully, MATLAB will then display the properties of the Arduino board connected to your system.

a = arduino()

Code for controlling LEDs using MATLAB and Arduino is as follows :

%create an object of arduino
a = arduino()
%blinking led for 5 secs
for i=1:5
    writeDigitalPin(a,'D10',1);
    pause(0.5);
    wrteDigitalPin(a,'D10',0);
    pause(0.5);
end
