A breadboard, solderless breadboard, or protoboard is a construction base used to build semi-permanent prototypes of electronic circuits. Unlike a perfboard or stripboard, breadboards do not require s

…are broken into isolated segments as required by scraping through the copper. This is similar to the pattern of default connections on a solderless breadboard. However, the absence of default connectivity on perfboard gives the designer more freedom in positioning components and lends itself more readily to…
