Based on request, here is a guide on redstone. If it's of importance to anyone, I will make it better. This was rushed.
This is a redstone torch.
Redstone torches will power the block above it.
As well as blocks to any of it four sides. (only one side is shown)
If a redstone torch is placed on a block, it will stay in its powered state.
If a redstone torch is placed on a powered block, the redstone will revert to its unpowered state.
A block can be powered from any side. (pressure plate is not activated in this image)
This can be used to make currents travel upwards, powering redstone on it.
A powered torch will unpower a torch above it, an unpowered torch will leave a powered one in its powered state.
This is a redstone repeater in its unpowered state.
Redstone repeaters can delay a current, and can delay it 1, 2, 3, or 4 ticks.
Two redstone repeaters set at one tick is equivalent to one repeater set at tick two.
Repeaters can also be used to send a current through a block. (block can NOT be transparent)
These are pistons. The one to the left is regular, the one to the right is sticky.
Powering a piston will push a block in front of it.
Pistons can collaborate with repeaters to create a functional gate.
Powering the piston on the gate allows a current to pass through the block.
A piston can not push a powered piston. (switch is off)
Pushing a powered piston will not do anything. (switch is on)
This is an example of a piston pushing a piston.
The second piston to the left is powered first so that it may retract before the first, because a piston in its on state cannot be moved.
This is an example of a piston clock.
Placing a block in it will cause a current to travel through it, powering a repeater, that leads to a piston, pushing to the block again to repeat the process.
This is an example of one of many redstone clocks. The current travels in a circle, while the repeaters delay it.
