Combining two sets of automation

[Glassyfo]

Hi, I've been trying to link this automation by SamLogan:

with this:

 

where the doors start closing just after the doors above finish mining the regolith. I found a post with Saturnus' positive edge detector, but I can't figure out how to make the negative version of that, where the doors stay open but close with a single negative tick. Can anyone help?

Anyone?

You can use a negative tick as a positive tick by using a not gate.  It is possible you might need a filter gate to maintain the negative signal for enough time.  Then you can use the positive edge detector.

You could loop the end of the sequence through a not gate, then an edge detector, then to the activating port of the memory toggle, attaching the output of the toggle to the sequence above and use the reset to trigger the initiation of the sequence

Here you go, a negative edge detector. Note that output is false for the filter set time so you might need a NOT gate anyway.

However you might not need an edge detector. The below outputs a TRUE for the buffer set time whenever the input is FALSE for more than 0.1s. In your application that's probably plenty.

I think I might have explained my needs poorly. When I mentioned a single tick my meaning was that the doors would close in sequence and then open and stay open until the next tick. So far they stay closed. As the setup is for the top of my space base, that isn't really an option. So I'm looking to somehow send a close signal down along the doors, then change the signal back to open until the next tick.

Okay so I think I got it. Credit to both SamLogan and Steve Raptor for their setups, I just combined the two,

The top half can be found here: 

The section with the memory gate can be found here: 

I set the leftmost buffer gate to 81s, which is how long the door mining took to complete. The timing for the bottom filter gate depends on how long the door sequence is (in my example it takes 10s for all the doors to close). At the end the filter gate resets the memory gate and everything opens.
