This is probably pretty easy in comparison to other topics, but I'm new to redstone, so bear with me.

I am making the entrance to a theme park. I would like the gate to be like this:





Where = Sticky Piston.

I would like the input to come from a button however I cannot get it to work.

1. I would like to hide all redstone, so that complicates things.
2. Having redstone dust underneath a piston does not activate it.
3. If I put a redstone torch underneath, is there a way to turn it off? I think I've done it before, I think it's called a T Flip Flop. Though, it's very complicated, and I need it to turn back off once the button pops out.

Thanks,

Have the dirt block be a redstone torch sitting on another block. Then have a wire running to the base of that block so the torch turns OFF when you apply power. That wire should come from the t-flip flop as you mentioned. You can put an inverter between the torch/block and flip flop so that when you apply power the piston powers ON.

are you making a gate that opens horizontally, or a gate that opens vertically? Also, how many pistons is your gate going to use?

Vertically. And only one.



I guess I wil have to make a T Flip Flop then?

I don't quite understand. Are you wanting it to toggle, or just have it open, then close with the button? Because that could make all the difference. And If you do need a t flip flop, I would recommend the one shown below, as it is the smallest I have found and works very well.

I would just like it to open with the button and reclose once the button pops out. I will probably just use the video though. Thanks!

Ugh. It's hard to get my head around.

I've built my monostable curcuit:



Now what?

This is a version of a monostable circuit or what I call an 'extender' that extends the signal length. I use it on my server because torch/block combinations have a tendency to fizzle from time to time.
This would allow you to push your button and have the gate stay open for longer than your standard button press. The extender circuits that are not in-line are on the 3rd tick.

Yeah, I think Crackerbear has you covered with his designs.

One thing I'd suggest, though, is change the half slab to a fence post and lower it 1 block. That way it looks like a fence till you hit the botton, then it drops into the ground out of the way.

Thanks, guys. This really helped.

Yea, I had that idea too, punchin. The only thing is that once the fence goes up, even with a sticky piston it doesn't come back down. It just stays attached.

With a button you could also use a T Flip-Flop method (not an expert T.T google a tutorial)

I don't know what you've tried, but it works fine with a fence:

Really? It works? Does the fence go back down?
