Is it possible to create a horizontal line on TV screen to be able to move it ??? Answered
Hi ... I would like to ask, if you know a way how to create a thin, horizontal line on your TV screen by using a device ???
Device is NOT a string, scratch on the screen, line with a pen ... (and not even PC)... by DEVICE I mean an circuit (micro controller, resistors...etc) ... and I should be able to move the line to any position I want (up/down).
EDIT : the line should be projected on the screen without having an effect on the background. So that you could watch a movie and see the line as well. A better example are the "driving lines" on a rear camera (z.about.com/d/trucks/1/0/s/Z/audi_q7_4169.jpg) This is, what I'm looking after.
Have you ever come in touch with something like this, or do you have an idea, how to create it ???
Thank you in advance .... zholy
