Tutorial - Using a Breadboard
about 4 years ago
Sadly, as of 1/13/2011, this article is incorrect. The article confuses “breadboard” with “solderless breadboard” (a), (b), and (d) are all correct answers.
Originally, breadboards were just that – wooden cutting boards. You’d put brass thumbtacks in them, and solder wires to those. It works surprisingly well – I’ve built circuits this way – but it’s fairly expensive, and finding real brass thumbtacks is a bitch.
A few steps forward in evolution, people made boards with holes (typically 100mil spacing). You’d stick components on top, wires through the holes, and solder on the bottom. Later, people added pads, and sometimes traces to those boards. Enter the modern (solder) breadboard. SparkFun sells these under the name “ProtoBoard” (which is funny, because prior to SparkFun, “protoboard” referred specifically to solderless breadboards of the modern variety).
A number of people made a number of types of solderless breadboards. These have the advantage of re-usability of components, and easy modification. There was a whole bunch of hokey schemes to do this (anything from nut-and-bolt terminals holding wires in place, to springs where wires would go between the coils), but eventually, the modern plugboard won out.
That’s what this article is about. Solderless breadboards. Generically, “breadboard” refers to a slew of different types of soldered and solderless prototyping boards.

The Eagle requirement seems somewhat silly. I know it’s free-as-in-beer, and I know you’ve got a great parts library built up, but productivity goes way up when you move away from hobbyist-grade tools…
