Dupont cables, also known as jumper wire, are used to wire components together when using a solderless breadboard. These cables come in three types: male-male, male-female and female-female. When using these cables with a solderless breadboard, and the Arduino, we typically use cables that have male connectors on both ends; however, there are some components that already have male connectors on them, so it is worthwhile having some male-female cables as well. The following photograph shows what the male connectors look like at the end of the Dupont cables:
It is pretty cheap to purchase premade Dupont cables but if you want to customize the length you can make them yourself by purchasing a crimper and some ends. These cables are not that hard to make but I would recommend starting off by purchasing premade ones.
