Redstone is one of the best features in Minecraft. It is a broader mechanic containing a core concept that governs many items and blocks in the game. Redstone is essentially a material that can emit power from one block or item to another. This power can then be used to operate all kinds of blocks, which help players create basic contraptions through which almost anything can be built.
There are many redstone components that players must know about for creating both basic and complex contraptions.
Note: This article is subjective and solely reflects the writer's opinion. There are many other redstone components that are important in their own ways.

Ranking important redstone components in Minecraft
10) Calibrated sculk sensor
The calibrated sculk sensor is a brand-new block added to Minecraft with the 1.20 update. While the regular sculk sensor activates at any level of sound, the detection and activation levels can be adjusted on the calibrated sculk sensor.
Once calibrated with a lectern and book, players can use the block as a wireless redstone component that automatically activates the contraption with nothing but a specific level of sound.
9) Powered rail
The powered rail is one of the most used redstone components in almost all Minecraft contraptions. It is relatively simple to use, as it can be placed on any solid block and be powered by a redstone torch. When activated, it will thrust any minecart ahead, making it move automatically.
Powered rails can also be used diagonally to push minecarts up a hill or mountain with one-block steps.
8) Lever
The lever is a relatively simple tool in Minecraft, but it is also an integral part of almost every redstone contraption. This block allows players to switch a redstone signal on and off in a contraption.
By flicking a switch when placed near a redstone-activated block, the lever turns the power signal on and off.
7) Observer
Observers are fascinating blocks to interact with, as they have the ability to observe what is going on in front of them. When a block or its state changes in front of observers, they send a single-tick redstone signal to the adjacent redstone-activated blocks.
For example, if a piston is placed below an observer, and it notices a crop growing and reaching its level, it detects that a new block area has been filled. It then sends a signal to the piston, which breaks the crop into items.
6) Piston
Pistons can push solid blocks away from them when activated or even break certain fragile blocks.
As mentioned in the observer section, pistons in Minecraft are mainly used with a redstone component that can activate and send a signal to it. They are also an integral part of almost all redstone contraptions in the game.
5) Redstone comparator
The redstone comparator is an important component in a number of Minecraft machines. In simple terms, it can take signals from all four corners and decide whether the main signal strength (the one going in line with the arrow) is greater or lesser than the secondary signal strength (the one going perpendicular to the arrow).
If the main signal is stronger than the secondary signal, the comparator sends the main signal through itself. It does not do so if the secondary signal is stronger. The comparator can also subtract the secondary signal from the main one and give an output signal of the resulting value.
4) Block of redstone
The block of redstone is one of the main sources of power in Minecraft contraptions. It gives power to any other redstone component adjacent to it. Since it gives a full 15 levels of power, it is used in many machines as the main source of energy.
This block can be crafted using nine redstone dusts. It can also be crafted back into dust.
3) Redstone repeater
As the name implies, redstone repeaters are mainly used to repeat redstone signals at any of the four given intervals. These intervals can be changed by right-clicking on the block.
Additionally, redstone repeaters can prevent a signal from going further in the chain and even add a delay to it. This makes them extremely useful in more complex contraptions that require automation of a specific kind.
2) Redstone torch
The redstone torch can send a strong signal to start any Minecraft contraption or machine.
Just like a redstone block, the torch gives out 15 levels of signal and can power various components. Hence, it is used in almost all contraptions, regardless of whether they are small or massive.
1) Redstone dust
When players first mine a redstone ore, they will obtain redstone dust, which is the core item from which all other components stem.
This item can be used to craft almost every redstone block. Apart from that, it is mainly used as a wire to connect one redstone block to another.
