minecraft-java-editionminecraft-redstone
I'm trying to create my first circuit in minecraft:
a – pressure platep – piston d – dirt- or | – redstone
a----dddd
pppp
Pistons are placed over the dirt and there's water under the dirt.
I'm trying this but it doesn't work:
a-------
ddd
ppp
This also doesn't work:
----
a ||
dd
pp
This does work, but only if pistons aren't adjacent
a--------
| | |
d d d
p p p
Here are two screenshots:
This doesn't work
This works:
As far as I understand your question, you have trouble with the track going trough the door...
Here is a screenshot of my setup, first you switch over to the new track, then you go trough the 'door', but by going down under the door block the track doesnt break and just creates a slope whenever the door is open, this would work in both directions.
Also as often happens with these timed things, the doors or track switcher might not stay open long enough, here is a way to lengthen that. (This is my own design, not all that compact, but the only thing that makes sense and works for me)
Come with me on an adventure in redstone optimization!
You can place Redstone Repeaters behind each of the pistons as shown below. This will direct the input into the piston and prevent those annoying loops that usually don't accomplish anything. This will take up much less space, but uses a total of 18 redstone dust.
A more redstone efficient design would be this. It uses only 11 redstone dust. Other players not required. This method works because a piston can be powered by an adjacent powered block.
This design (courtesy of Tristan) uses a minimalistic 7 redstone. The lever powers both the block that it occupies and the block it attaches to. The hole on the right is required to keep the signals going to the two pistons separate.
Finally, this uses a measly 4 redstone. Since you're powering 4 pistons, I think 4 redstone is likely as low as you're going to get.

There are actually a large number of different ways you can do this. Perhaps the simplest is using redstone repeaters, like so:
There's also the design proposed by StrixVaria, which uses elevated redstone:
But there are even more ways you can do this. Here are a few:
