HOW TO USE A BREADBOARD
The breadboard is a board used for creating temporary prototypes and experimenting with circuit designs. Prototyping is the process of testing out an idea or creating a model from which other forms are developed. The aim of this instructible is not to give you a complete guide on breadboard but to show you the basics.
The breadboard is made up of two major parts, the power strips and the component strips. The power strips consists of two rows. The first one for negative power supply and the second for the positive power supply. Each of the rows are connected together horizontally in 5’s.
The other major part is the component strip where the components of the circuit would be placed. They are connected vertically in 5’s. For example if I wanted to put an led in this circuit I would insert one leg into a free hole of one column and the other in a free hole of another column. This would complete the circuit allowing current to flow from one side of the power source to the other through the led. This description is shown in the image above.
