What can I use for jumper wires?

Wire in the 20- or 22-gauge range should be sought out. The gauge is commonly referred to as an AWG in the United States and other English-speaking countries (for American wire gauge). As well as needle-nose pliers, you also need a wire cutter and wire stripper, or a tool that does both jobs.
