Why Use a Solderless Breadboard?
An LED flashlight circuit uses just three components and is probably the simplest circuit you’ll ever build. It’s easy to package that circuit in a case so that it looks like a finished product (well, sort of — “Foam flashlights for sale! Get ’em while they last!”).
But as your circuits get more complicated, you’ll discover that it’s not always wise to create a permanent, packaged circuit right off the bat. What if you make a mistake and connect an LED backwards? What if you want to change the design of your circuit? You wouldn’t want to tear open your handcrafted foam (or other) packaging to make changes, would you?
Not to worry. Using a solderless breadboard, or breadboard for short, allows you to build flexible circuits that you can change whenever you want — without ripping permanent connections apart. And it’s actually fun — and easy — to build and play with circuits using a breadboard.
