Can someone help me make a simple coding?

I need help making a code that sends you a message “you got mail” after weight is applied to a pressure plate for more than 20 seconds. I know it’s a fairly simple code but I suck at coding and my professor didn’t help much this semester as she’s the worst professor I’ve ever had and the class has reported her to the dean.

Try this

startTime = tic
maxTime = 300; % seconds = 5 minutes
underPressure = false;
while toc(startTime) < maxTime
    pressure = GetPresure(); % Somehow ask your device for the the current pressure.
    if pressure > someThreshold
        underPressure = true;
        elapsedSeconds = toc(startTime);
        if elapsedSeconds >= 20
            uiwait(helpdlg("You've got mail!"))
            break;
        end
    else
        underPressure = false;
        startTime = tic; % Reset clock.
    end
end
