Koekytkentälevy

A koekytkentälevy, also known as a breadboard, is a construction base used for prototyping electronic circuits. It is a reusable solderless device that allows users to connect electronic components to form a temporary circuit. The name "breadboard" is believed to have originated from early days of electronics when components were sometimes wired together on a wooden board, similar to a breadboard.

A typical koekytkentälevy consists of a plastic block with a series of internal metal clips. These clips are arranged in rows and columns. When a component lead or wire is inserted into a hole, it makes electrical contact with the corresponding clip. The internal connections on the koekytkentälevy are designed in specific patterns. Usually, there are long power rails running along the sides, and shorter rows of connected terminals in the central area for component placement. This arrangement facilitates easy connection and disconnection of components without soldering.

Koekytkentälevyt are invaluable for hobbyists, students, and engineers for experimenting with circuit designs. They allow for quick iteration and modification of circuits, making the process of debugging and development much faster. Once a circuit is proven to work on a koekytkentälevy, it can then be permanently built using soldering techniques on a perfboard or a custom printed circuit board. The ease of use and reusability make koekytkentälevyt a fundamental tool in electronics prototyping.
