Let's say I have a 5×5 wall that has redstone torches on each block on one side:
Is there a redstone circuit that would allow me to power every block in this wall, so that all torches turn off ?
I'm pretty new to redstone, so forgive me if this is obvious.
Bob's Minecraft Tutorial, linked by Billy ONeal, is a useful resource, but I'll try to put the basics into words.
How is it possible for the torches to work as both input and output to a circuit?
Is there a practical difference between torches on the ground and torches on the wall?
Depending on where the torch is placed, neighboring blocks will be inputs or outputs, but each neighboring block is EITHER an input or an output - no blocks are both.
To summarize, torches on the ground output to their level and input from the level below.
In summary, torches on a wall output onto the ground and take input through the wall block.
What if two torches are both acting as output to the same redstone-wire? What if one torch is outputting positive/on/true to a redstone-wire but another is outputting negative/off/false to the same wire?
This has been answered elsewhere, but: If any power source hooked up to that wire is on, the wire will be lit up.
How do I read the diagrams on the minecraftwiki page?
Again, I'll try to break down the basics:
White and yellow squares can then have these items on them:
So, for example:
Within the MCRedstoneSim program you can change levels and see the wiring and such on each level of the circuit, but these extended types of blocks exist so that the whole circuit can be communicated with one set of symbols and no need to show diagrams per level.
If I understand your question correctly, here is a way of creating a "power ripple". Think of the sandstone blocks above-ground as ground level; I built it this way so it's easier to see. The circuitry would be underground.
Repeaters have an interesting property of being able to "power" blocks, causing the blocks to give power. Each Repeater in this image is powering the sandstone block in front, turning the Redstone Torch on top of them off, and is also powering the next Repeater.
When this button is pressed, the Redstone Torch turns off, causing the chain of Repeaters to slowly turn off, which also causes the Redstone Torches underneath to slowly turn on, in order.
The result is the line of Redstone Dust on the surface gradually turns on, and then gradually turns off.

I don't think it's possible, to power a block you need a wire running towards it, which it won't if there is another wire next to it (it'll turn into a corner, rather than a straight line, or a T if there is another wire on the other side).
