Before you solder wires permanently into place, it is important to test out the circuitry to ensure everything works as it should. Use a solderless breadboard when designing new electronic circuits. This allows you to adjust the design as needed. Newer breadboard designs allow you to use them time and time again. Strips of spring metal fingers are mounted in plastic perforated with holes. The numbers of clips, or points, are frequently listed in the description of the board. The spacing of the holes is standardized at .1 inch to allow for insertion of wires.
Breadboards come in a variety of sizes. The full size terminal board has anywhere from 56 to 65 rows while a small board only has 30 rows. Choose a board with enough rows to complete your project. Once you have worked out a design, then it is time to move on from the temporary solderless breadboard and onto a more permanent structure.
