The Hopper is a block with limitless power and it can literally sort items without using any Redstone Power, indefinitely! Use this fact to create highly reliable and independent automated systems like farms. You can place these Hoppers in multiple configurations - straight down or on either side.
Hoppers are not challenging to make but they can be challenging to fully utilize! Make sure that you understand the functionality of the item - items come through the top and are slowly filtered down to the block directly below it.
Open your Crafting Grid with a Chest and 5 Iron Ingots. Place the Chest in the middle and place the iron ingots in a V surrounding the chest to complete your hopper.
Any variety will do.
Simply put, all Hoppers have to have an input at the top and an output at the bottom. Think of a funnel- the logic works that way. Hoppers can be placed like any other block. These blocks serve as both functional sorting as well as storage, and the storage can be accessed much like a chest. However, Hoppers are meant to lead other items into a Chest or other storage solution underneath it. The primary usefulness of this is converting a mob farm into raw materials, but take a look below for how the Hopper functions in game.

Q. How is a hopper any different from picking up items myself?
The primary reason you would use a Hopper is when you are automating a system and the amount of materials is greater than your inventory space. When you are farming mobs for XP, you can easily fill an inventory full of Rotten Meat and other useless trash items. These items can be automatically deposited into a chest, which you can then dump habitually instead of constantly!
Hoppers are a huge boon for Redstone Engineers and other players that love to create fully automated systems. With Hoppers, you can finally work around the built-in despawn timer for in game items. Instead of letting items go to waste, automatically collect them using these useful blocks.
