Question

Iron

It is necessary to make the screen (TV or monitor operating offline) alternately display two pictures (a red cross and a green tick).
The image is selected by pressing a button. There should always be one of two pictures on the screen. The main question is what needs to be connected so that it can work.
Options - system unit, etc. unsuitable.

Answer 1

A flash drive with two pictures is enough.

Answer 2

Either you need a smart tv with a browser or some kind of mini pc like rpi.
Theoretically, two static pictures on TV can be output by an arduin, but this is already art.

Answer 3

I’ll still offer a photo frame with remote control to the heap. Of course, if such a screen size is acceptable.

Answer 4

I would suggest the most deshmanic android media player. Everyone can program under the bucket, you can connect the keyboard, the main question is how to run this program automatically.
