How to Use the Breaker, Placer and Rotator Together
Automated Breaking
Place a Breaker facing the block you want to remove. When it receives a redstone pulse, it breaks the block in front of it. Trigger it with a Copper Button, a Medium Weighted Pressure Plate, or a Redstone Counter output so each pulse removes exactly one block.
Automated Placing
Place a Placer facing the spot where the broken block should be replaced. Give the Placer the block you want placed by feeding it through a hopper or by inserting the item directly. A redstone pulse makes the Placer put the block down. Pair the Breaker and Placer on opposite sides of the same block position so one removes and the other restores.
Rotating Blocks
Place a Rotator against a block that can face different directions. A redstone pulse rotates the target block one step. Chain pulses from a Redstone Counter into the Rotator to cycle through orientations, or use a Copper Button for manual stepping.
Sequencing the Three
Run a single redstone line into a Redstone Adder, then split the Adder's output to the Breaker, Placer and Rotator in the order you want them to fire. Insert a Redstone Resistor on the line feeding the Placer so it fires slightly after the Breaker has finished. Use Redstone Glass to route the signals visibly along the machine frame.
