Arduino - Matlab

currently i use IO package for Matlab, i can light on LED by using digitalWrite function, but now i wan try to blink the LED but don't know how to do it, can someone help me?

You can check the elapsed time and toggle the output written to the LED every few seconds.

(It is not clear whether you are using the Simulink Arduino target, or something else here. If this answer doesn't help, please provide more information)

i didnt use simulink arduino target, just using IO packages, is possible i blink the LED without using it?

[Kaustubha Govind]

I'm not familiar with the IO package - does it let you read the clock on the Arduino? If yes, you can continuously poll the clock time and toggle every few seconds (maybe take the modulus of the time, and toggle the output value when it reaches a certain value).

It's not that hard. Check out the below code if you're using MATLAB Support for Arduino (aka ArduinoIO Package)

    % code
% ArduinoIO code for Blinking LED
% Connect to Arduino
MyArduino = arduino('COM1');
% Specify Pin Mode
MyArduino.pinMode(13, 'output');
for i = 1:10
    % LED on
    MyArduino.digitalWrite(13,1);
    % Delay for LED on time
    pause(.5);
    % LED off
    MyArduino.digitalWrite(13,0);
    % Delay for LED off time
    pause(.5);
end
% Close session
delete(MyArduino);

Or else, if you're using MATLAB Support Package for Arduino Hardware Try the below code. Hope this helps.

    % code
% Arduino MATLAB Support Package code for Blinking LED
% Connect to Arduino
MyArduino = arduino('COM1', 'UNO');
for i = 1:10
    % LED on
    writeDigitalPin(MyArduino,13,1);
    % Delay for LED on time
    pause(.5);
    % LED off
    writeDigitalPin(MyArduino,13,0);
    % Delay for LED off time
    pause(.5);
end
clear MyArduino;
