Jumper wires are used to connect devices through the breadboard. There are three types…

  • male/male
  • male/female
  • female/female

They can be any length and are critical if you want to build solderless prototypes or ‘play’ as I call it. They come in a whole range of colours. It is worth getting a set of each and for different lengths. They are very cheap and sometimes sold as a bundle with a breadboard and power board.
