when iam trying to run the third code (given below) the arduino status led blink that show it receive some thing but my actual led which is connected to pin 13 still off. It takes care of the serial communication between MATLAB and Arduino for you and maps most of the Arduino commands into MATLAB functions. i have tried may changes but cant able to do. But actually what i am trying to do is when matlab run code it automatically send 1 to arduino and the led become on.

arduinoserial ('COM4','BaudRate',9600) Now we need to open the arduino as if it were a file. Next set the baud rate you set in the Arduino code above. Establish a connection between MATLAB and the device using the serial port. Then it sends a uint16 (2 bytes) value of 500 to the arduino. matlab arduino simulink serial-communication arduino-due Share. Set the port to the port you are using to program the Arduino, am using COM4 to program it. After opening the serial port, the Arduino sends a 'Ready' command to matlab. Both code work fine and when i press 1 led lights up and when press 2 led become off. First we want to create an object of the class serial. I am trying to send data from MATLAB to ARDUINO using the following code for arduino and the second one for the matlab.
