Redstone comparator is a craftable block that comes with redstone circuitry. It resembles a repeater with an additional redstone torch.
To make a Redstone comparator, you will need Nether Quartz, Wood Log, Cobblestone, Redstone, Stone from Cobblestone using Furnace, Wood Planks, Wood Sticks and Red Stone Torch. Please follow the following steps to make Redstone Comparator.
In order to make a redstone comparator, one of the required items you will need is nether quartz. So you will need to enter into the nether to find and get at least one nether quartz using your iron pickaxe.
After that, the next required item that you will need to get is any kind of wood log. So chop down any of the trees using your iron axe to get that. You need to get at least one wood log.
Now the next required item that you will need to get is cobblestone. You have to get at least three Cobble stones. Use your iron pickaxe to get these stones.
After that, you will have to find and get Redstone. Use any of the pickaxes to get at least three red stones.
Stone from Cobblestone using Furnace
Now you need to use the furnace to make stone from cobblestones. Go towards the furnace and add three cobblestones in the upper box and coal in the lower box to get required stones in the right-side box of the furnace. Add these stones in your “ready to use” stock.
After that, make wood planks from Oak wood block you have collected. One wood block will convert into 4 wooden planks. Move to the crafting table and add wood block in any cell of the 3*3 crafting grid to get wood planks in the right-side box of the crafting table. Bring these wood planks in your inventory.
Now you need to craft sticks from wood planks using the crafting table. Add two wood planks in adjacent cells of any column, as shown in the image below. Two wood planks will give you four sticks. Add them in your inventory to use later.
Red Stone Torch
The next thing you will have to craft is a red stone torch. Add three red stones and three sticks in adjacent cells of any column, red stones in the upper cell and wood sticks in the lower cell as shown in the image below. You will get three Red Stone Torch in the right-side box of the crafting table. Bring these torch lights into the inventory.
Now finally you can craft a redstone comparator as you have all the required items ready in your stock. Open up 3*3 crafting grid to add three redstone torch lights, one nether quartz and three stones in the same way as shown in the image below. You will get a redstone comparator in the right-side box of the crafting table. Add this item in your “ready to use” stock.
