Not so long ago I was asked about solderless circuits kits. Snap circuits kits were the first that came to mind. Then I had to think a bit… And here we are: breadboard kits! But before going into details of any starter kits, let me tell you a bit about a breadboard and how to use it.
What is a breadboard?
Breadboard is a rectangular piece of plastic with lots of tiny mounting holes in it. In order to build electronic circuits quickly and easily, you need to push electronic components into these holes. You can create a huge amount of circuits, from the simple ones with a battery and on/off switch to control a light, to more complicated with automatically flashing lights and robots of all shapes and sizes.
About the origin of the word “breadboard” in electronics
Modern breadboards have nothing to do with bread. The name “breadboard” goes to the first steps of electronic circuits when people used wooden cutting boards with nails and crews to make electronic connections. Nowadays we call them projects.
Modern breadboards are made from plastic, and they come in all sizes and shapes, and sometimes, even different colors. The most common sizes are called full-size breadboard, half-size and mini-size breadboards.
Larger and smaller sizes are also available, and lots of breadboards come with notches and tabs on the side allowing you to snap two or more of them together.
How does a breadboard work?
The mounting holes of a breadboard allow you to insert metal legs, or leads of the components. Once any component is in, the connection is strong enough: it won’t fall out, and it’s very easy to take it out in case you made a mistake and need to place it in another location.
That’s why these types of breadboards are called solder-free, or solderless: new connections can be made without soldering.
What are breadboards used for?
Breadboards are used to prototype circuits.

Typical mistakes when building circuits on a breadboard
If you have never ever built any circuits on a breadboard, try to avoid the most common mistakes stated below:
- Wrong connection. Every time you build a circuit, double check the wiring and make sure the connections are in the right place.
- Not firmly pushing leads or wires into the breadboard. Make sure the connection is not loose, it stays secure and pushed firmly in all the way. In case the breadboard is moved, the LED or any other improperly fixed component may go out.
- Wrong polarity. Some of the components have polarity. It means that the direction they are facing matters a lot. Make sure you are using correct polarity. The best example is LED: the longer leg is the positive side, plus (+), the shorter is the negative side, minus (-). The Longer leg has to be connected to the battery pack’s red.
1) How does the breadboard hold components without solder?
If you flip the breadboard over, you will see an adhesive backing allowing you to permanently stick it to the project. If you remove the backing completely, you will see a series of metal strips that are inside the breadboard. These metal strips with clips are responsible for making mechanical and electrical connections to the components you place into the breadboard. When you push a lead into one of the holes, it’s being grabbed by the clips. Some breadboards are made from transparent plastic, so you can see the clips from outside.
2) What is the meaning of red and blue lines in the breadboard?
Red and blue lines are called buses, or power buses, or rails and are used to supply power to the circuit. Blue line is with minus (-) (negative), red line has plus (+) (positive). The red one labeled with a plus (+) needs to be connected to the positive battery terminal, and the blue one, with a minus (-) – to the negative terminal of the battery.
3) Do mini breadboards have power buses?
No, they do not.
4) How many holes are linked by a metal strips of any breadboard?
Usually there are 5 holes, linked by one metal trip.
5) Long leg – positive, short leg – negative. Is this rule applicable to all LEDs?
Yes. This is the way to distinguish two different poles of the LED, positive and negative.
6) Is it possible to make my own jumper wires?
Yes, it is. There are two options: 1) To buy a jumper wire kit with pre-cut to certain lengths wires. 2) To buy special spools of wire, so called hookup wire, and with a help of a wire stripper strip off some of the insulation and make your own jumper wire. Tip: if you decide to buy your own hookup wire, make sure you are buying solid-core wire (a wire, made of a single piece of metal; it’s very stiff and easy to push into the breadboard) and (made of multiple individual smaller strands, it’s more difficult to deal with).
Starter kits with breadboards are really a great fun to deal with. However, you should have some experience and basic knowledge of electronics and electricity.
In this review I wrote not only about kits but about types of breadboards and how to use them. Hope this information will help you not to get lost in the wide range of various tutorials available in the Net.
Good luck and have fun!
