Electronic basics: Prototyping using breadboards

In this image, you can see a simple circuit with batteries, resistors and LEDs.

The elements are displayed in a small white box called a breadboard:

The breadboard has 17 sets of 5 interconnected elements on one side and 17 sets of interconnected elements on the other side.

Under the surface, the 5 holes in a group are connected to each other, so we can easily establish electrical connections.

This is a small board that can be used for simple prototyping.

This is a bigger board:

The principle is the same, we have more elements on the outer boundary, these elements are wrapped in red and blue lines:

In this case, these items are orthogonal to the 5 element groups inside the board and connected longitudinally:

They are used to connect the positive and negative poles of the battery (or any other power source) to the board, so the elements on the board are easily accessible.

Usually the red wire is used for+Positive and black wire-negative electrode:

Usually, you use a breadboard to make a circuit prototype:

Once you are ready to move on, you can weld it to the perforated plate.
