A breadboard (solderless breadboard, protoboard, plugboard)'s a reusable sometimes solderless device used to build a (generally temporary) prototype of an electronic circuit and for experimenting with circuit designs. This's in contrast to stripboard (veroboard) and similar prototyping printed circuit boards, which are used to build more permanent soldered prototypes or one-offs, and can't easily be reused. A variety of electronic systems may be prototyped by using breadboards, from small analo… (More on Breadboard)
