Description:
The Redstone Comparator is a block for use with redstone circuitry. It resembles a repeater with an additional redstone torch. It has two inputs: one from the back, signal A; and one from the side, signal B. The output, the torch in front, has different behavior depending on the mode of operation: subtraction, which occurs when the torch is lit, and comparison, which occurs when the torch is dark. Right clicking the comparator will change modes.
In subtraction mode, when signal A exceeds signal B, it outputs proportionally to (A-B). Example: the back has a strength of 15, the side a strength of 1, and the output is 14.
In comparison mode, when signal A exceeds or equals signal B, it outputs signal A. Example: the back has a strength of 15, the side a strength of 1, and the output is 15. Compare Bipolar Junction Transistor (electronics).
If the rear of the comparator (the side with two redstone torches) touches a storage block, then the output is a signal that is proportional to the fullness the storage block is full (see below).
