Minecraft- With lever confirmation, lattice down and let high?

Hi, someone had been able to! If you confirm a lever, you could let grid down and drive up! How does it work?

He probably moved sticking pistons up and down with a Redstone circuit. Have a look at a tutorial on YouTube.

Either a lot of redstone or a plugin on a server.

If it was with redstone, maybe thejocraft?

Whereby with him only the technique with 2 buttons comes to mind ^^

Does not work! Pistons can only move blocks one block up or down!
