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
