Hello,

I am trying to enable and disable lamp after pause(1), i.e. one second interval.

by this:

ps = 10;
n = 1;
while (ps == 10)
                    fprintf('Hi!.\n');
                    app.Lamp2.Enable  = 0;
                    app.Lamp3.Enable  = 0;
                    pause(n);
                    app.Lamp2.Enable  = 1;
                    app.Lamp3.Enable  = 1;                    
end

It prints Hi! after each secon in the command window, but doesn't show the flasing the lamp. I tried changing the pause value to different values like 0.5, 1, 2 etc.

Still couldn't get output.

Also, I get sometime error like,

Invalid or deleted object., Just after the pause(1) line.

Can some plese suggest me into this?

Thank you

Ajeet - try using "on" or "off" (instead of 1 or 0) and add a pause after each change to the enabled property (so that there is a period of time for the lamp to be in that on or off state).

while (ps == 10)
    fprintf('Hi!.\n');
    app.Lamp2.Enable  = 'off';
    app.Lamp3.Enable  = 'off';
    pause(n);
    app.Lamp2.Enable  = 'on';
    app.Lamp3.Enable  = 'on'; 
    pause(n);
end
