Here's what I know that used to be on this page. Comparators are redstone items that are used to compare, subtract, and measure block states. They can also detect the fullness of containers. The comparator is in comparing mode when the front light is off. In comparing mode the comparator will give an output when the back input is stronger than the side inputs added together. For example, if the rear input is 12 and the side inputs added together is 5, the output will be 12. If the side inputs were 14, the output would be off. The comparator is in subtraction mode when the front light is on. In subtraction mode, the comparator takes the side inputs and subtracts it from the rear input. For example, if the rear input is 15 and the side inputs add up to 7, the output will be 8. When the comparator is used for detecting block states and container fullness, it will send a certain signal to the comparator based on the state or fullness. For example, if a cauldron is facing away from a chest (could also be from a block if the block is adjacent to the container of choice), the comparator will output a signal depending on how many items are inside the chest. If the chest is full, the output will be 15. Another example includes cake or an item frame. When a comparator is facing away from the cake/item frame, the comparator will output a power based on it's state. If the cake hasn't been touched, the output will be 15. If the cake has been almost completely eaten, the comparator will output 4. If there is nothing in the item frame, no power will be output. If there is an item rotated 3 times in the item frame, the output will be 4. I hope this helped
