Explore the fundamentals of utilizing a breadboard to prototype and test circuits.


A breadboard is a great way to begin prototyping your circuits. That is, trying them out to see how they function, and whether or not you want to move on to a soldering job. Breadboards are basically plastic platforms formed with embedded metallic channels that provide insulation from adjacent current, and provide an easy means of experimenting with circuits before you move on to making the decision to solder them together.
