Show A Blinking Arrow In A Picturebox?

In my form, there are many controls and the people who will use the final program are not very computer literate people. For this reason, I would like to use arrows which blink beside the control in order to show the order of controls to use (just like a visual guide). I also make the controls active-inactive in a proper order but a visual guide will also be musch of use...I guess I can do this by either using picture boxes beside each control or draw method (which I do not yet know how to use). But if I use a picturebox, how will I give the blinking (or fade in & out effect)? For blinking effect, should I use a timer or anything else?
