Hi guys, I want to make like this code using matlab ...

void loop() {
  for (int thisPin = 2; thisPin < 8; thisPin++) {
    digitalWrite(thisPin, HIGH);
    delay(500);
    digitalWrite(thisPin, LOW);
  }

but the problem is the matlab has this format and you can not change the pins in loop see this

writeDigitalPin(arduino, 'D2', 1);

Here I can only change the pins manually but how I can make like above code in loop which the pin change every time ..

Hi

You can use num2str() and change the number during every loop. I tested using Matlab R2016a with this code and LEDs hooked up an Arduino on pins 3-5.

for i = 3:5 
  writeDigitalPin(a, ['d' num2str(i)] , 1)
  pause(1)
  writeDigitalPin(a, ['d' num2str(i)], 0)
end
