How to make observer in Minecraft?

In Minecraft, an observer is a redstone component that can detect changes in the surroundings and emit a redstone signal. Six cobblestone, two redstone dust, and one nether quartz are required to construct an observer. Place the cobblestone and nether quartz in a “C” shape on the crafting table, and fill the remaining spaces with the two redstone dust. This will result in one observer.
