Test Your Electronics Circuits Using a Solderless Breadboard

A solderless breadboard — usually just called a breadboard — is a must for experimenting with electronic circuit layouts. A breadboard is a board that has holes in which you can insert either wires or electronic components such as resistors, capacitors, transistors, and so on to create a complete electronic circuit without any soldering.

When you're finished with the circuit, you can take it apart, and then reuse the breadboard and the wires and components to create a completely different circuit.

A breadboard can be purchased from RadioShack for about $20. You can purchase less expensive breadboards that are smaller, but you’ll be happiest with one that is 7 x 4 inches or larger. If you really get into your electronics, you’ll want to buy one of this size as well as one or two other, smaller breadboards. That way, you won't always have to take one circuit apart to build another.


What makes breadboards so useful is that the holes in the board are actually solderless connectors that are internally connected to one another in a specific, well-understood pattern. Once you get the hang of working with a breadboard, you'll have no trouble understanding how it works.
