Matlab Arduino: Problem with turning on Leds in Sequence

Hello

Before anything I just clarify I´m still a noob in matlab. That said Im working in a script wich makes a real time adquisition of some voltage values via the Arduino A0 analog input. Depending on the voltage the leds must turn on in a sequence like a roulete (in circles). The problem is the code im using to turn on the leds

while t<inf
    
% All the adquisition and plotting code here

    if PB(t)<PBC(t) % This is my conditional and works fine
        writeDigitalPin(a,'D7',1)
        pause(0.5)
        writeDigitalPin(a,'D7',0)
        writeDigitalPin(a,'D8',1)
        pause(0.5)
        writeDigitalPin(a,'D8',0)
    
    % And so ON
    end

end

The thing is that Im plotting in real time the values and the Pause inside the code is disrupting my adquisition. Is there a way to run the conditionals in paralel with the adquisition script so it doesnt disrupt the plotting? Cause another idea on the way is that when the conditional is not met again to do a "break" and stop the leds from "rotating".

I would be most grateful for any help, idea, hint or clue in this matter.

Thanks to all in advanced for the help

Assuming if your condition works properly,

you can tackle the issue by bypassing the pause function and controlling the LED's using flags.

LED1 = false;

LED2 = false

while t<inf
% All the acquisition and plotting code here
    if PB(t)<PBC(t) % This is my conditional and works fine
        writeDigitalPin(a,'D7',1)
        x=datetime;
        % And so ON
    end
    if(datetime-x >1)
        writeDigitalPin(a,'D7',1)
    end
end

this code will bypass the pause function.
