Jumper Wires

Jumper wires are used to connect two terminals and are essential for prototyping circuits. While jumper wires come in various types, this explanation focuses on those designed for use with breadboards. These wires are commonly used to transfer electrical signals between different points on a breadboard and the input/output pins of a microcontroller.

How They Work

Jumper wires are connected by inserting their “end connectors” into the slots on the breadboard. Beneath the breadboard’s surface, parallel metal plates connect the slots in grouped rows or columns, depending on the section. The “end connectors” are inserted into specific slots to establish connections in the desired prototype, all without requiring soldering.

Types of Jumper Wires Jumper wires come in three main types: - Female-to-Female: Both ends have female connectors. - Male-to-Male: Both ends have male connectors. - Male-to-Female: One end has a male connector (a protruding pin), while the other end has a female connector (a recessed socket).

These variations make jumper wires versatile and suitable for connecting components with different pin configurations. img_wire

Note

  • More than one type of them may be used in a project.

  • The color of the jump wires is different but it doesn’t mean their function is different accordingly; it’s just designed so to better identify the connection between each circuit.
