Display countdown at event

[joseaguardia]

Hi!

I’ve a python script running, and when I press a button it takes a photo. I want to display a 3 seconds countdown after that.

The easiest way (not the best) maybe that a module of MagicMirror display dynamically the content of a text file, and in python script I write to that file.

How can i do that?

Do you know any way to do that?

Regards.
