Hello everyone,
This is all 12VDC, BTW. I have a very simple situation where a signal is making an LED light up. I have to work with the signal I'm getting, which is initially off, then on, then off, then on again. And I need to negate the final 'on again' so in other words, rather than having this light go off and then on again, I don't want it to come back on after it goes out. In case it matters, at present it comes on for about 4 seconds, then goes out for about 300ms, then comes back on permanently. I just want it to *stay off* rather than coming back on after the 300ms of zero volts. Sorry if that's over-explaining it! I think some kind of latch would do it, but it's so long ago I studied electronics I can't remember. Any help appreciated, thanks.
