Concept:  Finding a solution

Once the engineer has made a preliminary design on paper, the initial electronic concept design is often built up using either a breadboard or plug board as shown above.  This allows the electrical engineer the freedom to experiment easily while testing out the design.  A variety of electronic systems may be prototyped by using breadboards, from simple small circuits to entire CPUs.  Of course, complex circuits can become unmanageable on a breadboard due to the large amount of wiring necessary.  These more complex circuits are often "breadboarded" on the computer using simulation software.
