I built a redstone circuit. A Secret Piston door that opens through the redstone signal from the reading desk when you turn the pages. But now the signal is so short that the door opens ne half a second.
So how can I have the signal repeated several times? So it takes longer?
You could build something with repeaters that close the door after a while.
You could build a T flip-flop that can be reset from the inside:-)
E.g.: dad reading desk triggers an observer that causes a slime piston to push a block forward. Due to the short signal, however, he does not initially withdraw the block; you can then use the block as a "switch" for the door and simply push or pull it back if necessary:-)
I'm available for further details
