I have various things going on... and would like to add some.
I have a CCTV system I would like to have a display (VGA, at least), with a "slide show" (Series of jpgs) I have a weather parameters datalogger...
My dream? All of these on ONE screen... a full size display, like the screen of a "big" computer.
It would, for 30 seconds, display the input from the CCTV system after "an event" (e.g. a PIR tripped).
It would be possible for me to press a button, rather like making a choice with a KVM switch, to say "show me the current weather readings".
If neither of the above were invoked, it would be showing me the output from whatever generates the slideshow.
Here was my thought... what do you think?....
It is easy, today, to buy a small screen intended for displaying TV. With multiple inputs... some of them HDMI. And an IR remote control, which, among other things, lets you tell the display which input to feed through to the screen.
Why not, I said to myself, connect up the CCTV, the slideshow, and the weather data system outputs to the sundry inputs to such a TV (yes, I realize that the resolution, etc, might not be as good as on a modern dedicated display-for-a-computer).... and then set up an Arduino with an IR transmitter, and use THAT to emulate a person saying "show the CCTV feed"/ "show the slideshow", etc, depending on inputs to the Arduino?
Anyone played with this sort of thing? Anyone spot any "gotchas" which are going to annoy me, down the road? (Yes, I do realize that controlling a TV with an IR diode on an Arduino isn't trivial... but I've done it. Can manage that part.)
Forgive me if it seems a "dumb" question, with only "Well, of course you COULD..." as the answer... but while it seems like that to me at the moment, if any of you spot a major "but...." to break the deal, I'd be grateful to hear you thoughts.
(I can work out the exact details of the "how" for myself, at least if it goes ahead as sketched. I thought I'd appeal to the community for suggestions as to whether the PLAN seems okay, whether the plan could be tweaked before I spend time developing a flawed "answer", and have to backtrack to go around something I failed to see, further down MY "road".)
