Jumper Wire, 140 Pcs Breadboard Jumper Wire Kit 14 Lengths Assorted Jumper Wires with Storage Box Jumper Cable

now let's take a look at jumper wires jumper wires are used to make connections between components when building your Arduino prototypes you know it sounds like a simple topic it is but I've got a few tips and tricks first of all most jumper wires that you're going to want to build when you're using red boards or building any kind of circuit is solid core and what that means is that there's one conductor in this wire there's stranded which would have multiple conductors and solid core solid core typically will hold its position but more importantly when we strip the end of a wire it allows us to easily insert it into something like a breadboard and it will stay there use stranded wire good luck it's not easy to do there are ways of making it work but you don't want to use it in general so this is 22 gauge you can typically buy them in sets this is a multicolor set and it works beautiful
