koekytkentälevyillä

Koekytkentälevyillä, known in English as breadboards, are essential tools for electronics prototyping. They are reusable circuit construction bases that allow users to build temporary circuits without soldering. A typical breadboard consists of a plastic block with a grid of holes. Beneath these holes are metal clips that connect groups of holes together.

The holes are arranged in rows and columns. Usually, the central section has columns of holes arranged in pairs, intended for component leads. These columns are typically separated by a gap, allowing for integrated circuits to be placed across it. Around the edges, there are often long, continuous rows of holes, referred to as power rails. These are typically used for connecting power and ground connections to the circuit.

Components are inserted into the holes, and their leads make electrical contact with the internal metal clips. Jumper wires are used to create connections between different parts of the circuit, bridging the gaps between component leads or connecting them to power and ground. This non-permanent nature makes breadboards ideal for testing circuit designs, making quick modifications, and learning about electronics.

Breadboards come in various sizes, from small, portable versions to larger ones with more connection points. They are a fundamental piece of equipment for hobbyists, students, and engineers alike, facilitating rapid development and experimentation in the field of electronics.
