Question

I need help converting this arduino code into matlab code.  

The set up has two resistors(10&330) with a button and a led.  

Here is what I have so far......

a = arduino('COM4');

a.pinMode(13,'OUTPUT');

a.pinMode(5,'INPUT');

while isvalid(a)

..I think it is right up to here.......

a.digitalWrite(13, led);

a.digitalRead(5);

=======same as picture==================

#define LED 13 // the pin for the LED

#define BUTTON 5 // the input pin where the

// pushbutton is connected

int val = 0; // val will be used to store the state

// of the input pin

void setup() {

pinMode(LED, OUTPUT); // tell Arduino LED is an output

pinMode(BUTTON, INPUT); // and BUTTON is an input

}

void loop(){

val = digitalRead(BUTTON); // read input value and store it

// check whether the input is HIGH (button pressed)

if (val == HIGH) {

digitalWrite(LED, HIGH); // turn LED ON

} else {

digitalWrite(LED, LOW);

}

}

===================================

Explanation / Answer

a = arduino('COM4');

a.pinMode(13,'output'); % 13 pin output

a.pinMode(5,'input'); % 5th pin input

loop=1; % variable for looping

val=0; % val will be used to store the state

while loop==1

     val=a.digitalRead(5); % read button

     if val==1 % if val is high

        a.digitalWrite(13,1); % write high on 13th pin

     else

       a.digitalWrite(13,0); % write low on 13th pin

      end

end
