Breadboards and solderless circuits
We can create circuits with electrical and electronic components such as LEDs, wires, and buttons. We need to use the soldering method to connect them to make them work. However, there is another method we can use to avoid soldering altogether. This method is known as breadboarding or prototyping. We have to use a component known as a breadboard to avoid soldering other components. The following is an image of an MB102-type breadboard:

A Dual In-Line Package Integrated Circuit (DIP IC) is mounted on the breadboard. Let’s see how breadboards are useful. Have a look at the top view of the breadboard:
