this is what you can do (L = lever, A = and gate, D = door:

L------------            D
                |            |
                A ------ A ----
                |                   |
L------------           -------
                            |
                            |
                            |
L---------------------

if you dont know what an AND gate is look it up on youtube, you should find it. If this still doesnt help I can make you a diagram
have a question about redstone? email me about it at BladeOfTheEast@gmail.com.

I don't think that's what he means, I assume you mean how can you use more than two levers to open/close a door. With two levers you can use a xor gate, with more than two you should use a T flip flop.

So, find designs for a t T flip flop and wire all levers to it's input (separately). Should work just fine.

Due to the lack of information (or simplification of it), I'll assume it's a question of "all 3 levers must be pulled before the door will open":

In the politest way possible, you're all stupid. Read the original post again. He figured out how to open a door with three levers, he wants the system to give him three tries to open the door, then trigger an output.

I can't tell if you're being sarcastic or not....

Nothing is said about three tries... or anything similar. There is a bit of a lack of info though :P

Alright guys sorry for the lack of info.  I want to be able to make a door open or close with 3 switches and have the switches in any position and still be able to open and close the door.  Let me know if this is not enough info still.

then you would use an XOR gate or 2.

basically, just set 2 of the levers into an xor, then put the output of the xor and another lever into another xor

like this:

L--
  |-------
L--    |------
L-----------
where each L is a  lever, the --- is redstone, and the | represents an xor

this is the minecraftian equal. I play in quake pro, so things will look stretched on the end. the line on top is an output line, since I have used this design before for some friends.

Yeah that's what I thought when I answered.. so go with a T flip flop. :P

im obviously hooking something up wrong and cant get it to work. How closely related is all of this to electricity.  Is it exact or just close?

Not even remotely close to electricity.

It's pure digital logic. Nothing whatsoever like actual circuit design, just that you can do some similar things with it.

What design are you building? Also, pics. With only that info, the best answer I can give is "Then build it correctly.".
This signature is now 20% cooler. That's what I'm counting on.

Well i do not know how to upload pictures.  And i built a t flip flop and two xor gates connected them almost every way possible so i don't think im using the right three circuts.

Jesus christ. I try to stay away from these threads because they get so many responses which confuse the OP even more, but I feel sorry for him if after 16 tries you guys still haven't come up with a valid response.

> Three levers
> Clicking any of them will open a door

All you need is an XOR gate going into another XOR gate.

You can use any of the designs from this thread, I used #2

You could just use 3 dual edge monostables (with repeaters to extend the signal time) hooked up to a single t-flip flop. This would be fairly compact and easy also

Thooough not as compact or as easy as what Magix posted. Also as he said, this only contributes to confuse the OP, because a definite better answer has already been given
