In order to run iteratively, you need to call readDigitalPin in while loop or for loop.
If you want to run specified times, for example, 100 times with an interval of 1 second, add the following in startUpFcn callback.
a = arduino('com8','uno');
iter = 0;
while iter < 100
b = readDigitalPin(a,'D3');
if b == 1
app.Lamp.Enable = 'on';
else
app.Lamp.Enable = 'off';
end
iter = iter + 1;
pause(1);
end
If you want to run forever, you can use while loop in startUpFcn callback.
a = arduino('com8','uno');
while true
b = readDigitalPin(a,'D3');
if b == 1
app.Lamp.Enable = 'on';
else
app.Lamp.Enable = 'off';
end
pause(1);
end
You can stop the iteration by Ctrl+C.
