Struggling with millis() for two tasks

[Terrypin]

@alto777

With the KA gap of 5 and the short Video test length, it's actually kinda hard not to get a KA tap after the end video tap.

Adding the scoot thing I suggested above fixes that: reset the KA tap timing right after the video finishes and you won't get a KA tap piling on.

The input pulse is plenty long, too long for 4 second testing in fact, but OK for the longer video interval.

You were dead right about the cause being down to my code, not the excellent Wokwi. Sorry it took me so long to get that!

I thought the obvious correction would be to simply reset the KA interval timer directly after the video, as well as at the end of the KA section.

But that kills the KAs, so still pondering. Millis still gets me in a mess sometimes
