Jumper wires are simply wires that have connector pins at each end, allowing them to be used to connect two points to each other without soldering. Jumper wires are typically used with breadboards and other prototyping tools in order to make it easy to change a circuit as needed.Male ends have a pin protruding and can plug into things, while female ends do not and are used to plug things into. Male-to-female jumper wires are the most common and what you likely will use most often. When connecting two ports on a breadboard, a male-to-female wire is what you’ll need.
