Many thanks for the detailed follow-up.
I've no idea why, but the simulation seems to part from reality in one major way. On triggering with a brief press on the button (emulating the low from my motion sensor) it correctly delivers two presses (to start the video). But to end the video it again presses twice instead of a SINGLE press.
I'm determined to persevere with learning how to use wokwi. This is despite being unable to do so properly in my iPad's Safari browser because of having no paste facility. So I'd much appreciate it if you can spare a little more time to get going. And if we can be excused for going a tad OT.
I'm struggling to draw a test schematic from scratch. Perhaps because strangely the list of parts does not include the UNO itself? So I started with your neat schematic. I deleted all but the UNO, and added an LED (ensuring it was blue!). Similarly, I deleted your code and pasted in my trivial example.
But how do I proceed from here please? If I try 'Save a copy', nothing appears to happen. There's no 'Save As...' dialog. And a search of my PC finds nothing relevant. What type of file does it create and what sort of name?
If instead I use 'Share Project' it appears that it would save this link:
That's the the one you gave me, so it would presumably overwrite yours?
Perhaps a 'shared project' is the only sort of 'Save' possible? If so, how did you give yours a unique name?
