Combinator setup

[Lordme]

Hi all,

I want a system that can pick up 3 copper cables and then 1 iron plate and then again 3 copper cables etc. with a single inserter, but I can´t seem to figure it out how to get the system working.
What I want is some kind of if-else statement, but the main problem is to memorize what the inserter picked up last, since if he drops it, it sends no more signal of what it grabbed last.
I think what I need is some kind of memory cell that remembers the last thing the inserter grabbed en resets when it picks up the other item.

Does anyone have ideas of how I can realise this?

You'll need to use a filter inserter, obviously. As for a memory cell, have you tried seraching for that on the forum? I'm sure that someone has come up with one.

You can remove the far right combinator after everything is powered up.
