What exactly is a Solderless Breadboards and how do they work?
In: 11
When working with electronics you typically solder a component to the board which houses the logic of the device. This is done to form a permanent bond between the component and the board.
A solderless breadboard is just that, a board for which you do not have to solder anything onto it. You insert the component into the board and it functions as long as you insert them into the proper circuit.
Depending on the board, typically it’s composed of a power rail and sections. Each section represents its own circuit, and they can either act independently or dependently depending on how you place your components.
It’s useful as it allows you to quickly swap out components during a development process.
It’s a board with a lot of holes in it. Like hundreds. And they are arranged in rows and columns. All the holes in a column are wired together. You use a breadboard to test a circuit when you are designing it. With all the holes, you push the wires coming out of the components into the holes. To connect two components together, you push their wires into the same column of holes. Makes it easy to test things.
Back in the day, prototyping a circuit required soldering all the parts together and seeing if it worked. This works okay when everything is soldered together perfectly, but if something goes wrong troubleshooting gets more difficult as you have to de-solder and re-solder different components in order to re-test the circuit.
A solderless breadboard works by having a big pattern of holes with spring-loaded metal contacts inside so that when you push a wire into the hole it makes good electrical contact as-if you had soldered it into that hole (but still being easy to pull out later). Solderless breadboard designs then connect a number of neighboring spring-holes together (usually a row of 5) so that you can connect up to five wires together just by pushing 5 wires into those 5 holes. This means that when you’re troubleshooting a circuit that isn’t working, when you see “Oh, this resistor is in the wrong place!” you just have to pull it out of the wrong holes and plug it into the right holes (instead of having to de-solder and re-solder it).
A solderless breadboard is just a piece of plastic with metal inside of it, so you can quickly make electrical connections for prototyping an electrical device.
There’s a bunch of little holes, and those holes can take in wires to make contact with a piece of metal. That metal carries the electrical current to nearby holes so you can attach the next component.
Generally, there’s a red rail, blue rail, and the rest of the holes on the main breadboard. The red rail is for the positive voltage, the blue rail is for negative voltage or ground. All the holes on the red rail are connected to each other, and all the holes on the blue rail are connected to each other.
The rest of the breadboard usually has many rows of 5 holes. Each row of 5 holes are connected to each other.
This allows you to quickly place, remove, and change electrical components. If you didn’t have this, you would need to constantly solder and unsolder components (which takes time and precision). Soldering it when you take a piece of metal (usually called flux or solder) and you melt it over the leads of 2 components or wires to attach them together.
