Redstone circuits

A redstone circuit is a build that is primarily focused on dealing with logic and redstone signals. Circuits can be used to transmit redstone signals, perform operations with logic gates, store information, shorten or lengthen redstone signals, make clocks, and more.

A useful distinction can be made between a circuit performing operations on signals (generating, modifying, combining, etc.), and a mechanism using the environment (moving blocks, opening doors, changing the light level, producing sound, etc). Making this distinction allows us to talk about the various circuits separately, and let all players choose whichever circuits are useful for their purposes. The machines controlled by redstone circuits can range from simple devices such as automatic doors and light switches to complex devices such as elevators, automatic farms, or even in-game computers. However, this article provides only an overview of redstone circuits as above. These can be used to control simple mechanisms, or combined as parts of a larger build. Each circuit type on this page has links to its own page, which provides greater detail about them and give schematics for multiple variations of each.

Before working with any but the most basic redstone circuits, an understanding of some basic concepts is required: "power", "signal strength", "redstone ticks", "block updates", etc. Some relevant articles are listed below:
