I'm trying to make a base with a hidden door that can be opened from the inside and outside. I was wondering if there was a way of making a circuit that could be operated from two different switches allowing me to operate the door from the inside and outside. Here is a picture that shows the hidden door in its open status.enter image description hereSorry its a bit blurred, but hopefully you can see what's happening.

Instead of using a camera to take a picture of your screen (which results in blurry images as above), you should use print screen instead in the future! (You can either use the Prt Scr button on your keyboard (if you have one) or some screen clipping software) –  chandsie May 20 '12 at 16:06

Or, use Minecraft's built-in screenshot system. Just hit F2. –  Alexis King May 20 '12 at 21:02
    
I would but i cant find where it saves the pictures –  mrminecraft3000 May 21 '12 at 20:45

Normally, it just saves them to your minecraft folder under "screenshots". –  Xeo May 21 '12 at 21:00
    
thanks for the info on screen shots. –  mrminecraft3000 May 22 '12 at 17:57

What you need is an XOR circuit.

An XOR circuit allows either switch to change the state of the door (open/closed). This means the door can be opened or closed using either switch and it doesn't matter if the other switch is up or down.

I have done this but it can be tedious trying to get the Redstone to laid out correctly. In the diagram in the link A would represent a switch on one side of the door and B would represent a the switch on the other side.

The easiest Redstone XOR gate to create IMO is the "F" style on the wiki, because it's only 1 block high. –  Broam May 22 '12 at 20:28
