I see many Instructables, and other electronic projects using breadboards nowadays. Some people might think, "what is that?", or "How do I use it?" This Instructable will be used to help you answer those questions!

Breadboards are used for testing and experimenting with electronic circuits. I find them extremely convenient because they require absolutely NO soldering, and you just have to plug the component into the little holes that are provided on the breadboard.

Iguana Labs gave a few of these pictures and explanations. Thanks Iguana Labs!

## Step 1: The Breadboard Connections

Breadboards consist of tiny "holes" in which the leads of the component connect into. Make sure that if you are using wire, use wire links, not the stranded wire, because it will crumple in the holes and damage your breadboard.

The top and bottom rows (the rows indicated by the blue) and are usually the (+) and (-) power supply holes and these move horizontally across the breadboard, while the holes for the components move vertically Each hole is connected to the many metal strips that are running underneath.

Each wire forms a node. A node is a point in a circuit where two components are connected. Connections between different components are formed by putting their legs in a common node. On the bread board, a node is the row of holes that are connected by the strip of metal underneath.

The long top and bottom row of holes are usually used for power supply connections.

## Step 2: Connecting the Components

The rest of the circuit is built by placing components and connecting them together with jumper wires. Then when a path is formed by wires and components from the positive supply node to the negative supply node, we can turn on the power and current flows through the path and the circuit comes alive.

For chips with many legs (ICs), place them in the middle of the board so that half of the legs are on one side of the middle line and half are on the other side.

A complete circuit might look like the one below.

I have two questions:

1. If I understand correctly. From the article it says all the components are hooked together. So do I have to run wire from every component to eachother?
2. How can I understand the circuit pictures such as the second set of pictures on http://www.instructables.com/id/Arduino-RFID-Door-Lock/step3/Build-the-RFID-Reader/?

Sorry, I'm new to this- can you explain what jumper wires are? I googled it but they just look like very short wires with the insulation stripped off the ends.
Stormed Wolf in reply to TheJenx2 years ago
Thats really all they are, You can buy them in kits that come with several different lengths. They're much more convenient than stripping your own wire.

What the hell am i supposed to to do with the metal sheet that came, does it go on the back...why? (i assumed it went on back because of ahesive on it)
Stormed Wolf in reply to sam484152 years ago
They can be used (not ideally) to replace broken connectors on the back of the breadboard. Other than that, it doesn't really have a purpose. Although If one of those ever breaks you might as well just go and spend the money on a new one.

I'm a Sophomore in a High School for Construction Trades Engineering & Architecture ( Btw that's actually my Skool name) , and I'm Majoring In Engineering, and in my school they Teach Digital Electronics to engineering sophomores, and my Teacher demanded that we all get a BreadBoard, since then he's been teaching us how to do all of this stuff, today actually learned about parallel circuits, and some times i just don't understand what he is saying, not because this stuff is hard, but only because he has a thick Egyptian Accent, anyway i just wanted to say this Actually helped a lot, Homework is a breeze, thankss!!!

I am glad to hear it! Good luck in your studies, and stick with it!
Astro8Nerd in reply to Brennn103 years ago
Thanks i will, But can you give any tips on connecting LEDs? im actually stuck doing this, and i my teacher really never explained how exactly we do it

can u tech me?
YellowZealot in reply to elpaps19933 years ago
That's what this instructable is for. Read it, CAREFULLY, and for the love of god spell correctly.
D_H says: 3 years ago
Good Lord! I just bought a breadboard.
Seriously got curious and broke it apart to see what it was inside
Its got some comb like structures. So... anyone planning to break open their board , save it.... (Nice Instructo there buddy)!

thx. Its surprising to me how much ive learned about electronics(aka how much ive become a geek-_-) through instructables!!!
zoltzerino in reply to geeklord4 years ago
I agree with geeklord - a complete ditto of his comment.
fallenspirit123 in reply to geeklord5 years ago
Yeah, don't even get me started!!! man I love instructables!!!! This instructable has taught me alot

instructables are awesome
TheWelfareWarrior says: 5 years ago
Wow, thanks, I just bought a solderless breadboard (i figured it'd save me messups on a regluar one) on a whim and couldn't figure it out for the life of me. Whats the most curent i can put to this bad boy?
DYLEGO in reply to TheWelfareWarrior5 years ago
you treat it just like wire. put as much current as you trhink fit. i wouldn't put more than a few thousand volts on it, just to stay well out of the peak voltage range... how many volts are you wanting to put in?
TheWelfareWarrior in reply to DYLEGO5 years ago
current... or amps... are what make heat/fry things...
vivennex says: 5 years ago
Thanks mate for the information.Instead of damaging the parts of the bot with soldering its better to breadboard the circuit before.

Dang im still pretty confused but this has helped alot ! Thanks Brennn10 :D

Nice ible, it's nice to see someone covering electronics basics in a clear, and comprehensible manner. One mistake I saw, is that on the intro image, you mention "rows" when you point at columns. You might want to double check.
Derin says: 5 years ago
oh man the strands are nothing i broke a graphite lead inside one
fortneja says: 5 years ago
Ugh, I hated these things in my electronics class (e-fundies), and I was very relieved to finally just solder everything. They are good for beginners and labs, though.

Looks like a big chunk of this instructable was taken directly from:
IguanaLabs
If you aren't associated with them, please at least give them credit.

OH and thanks for posting it, i learned something new.
Brennn10 (author) in reply to znorris6 years ago
Done, and done! Thanks!
Scissorman says: 6 years ago
I bought one a few weeks ago. Breadboard, jumpers etc. I just don't have any components yet. Yah Boo sucks to me. I will be back to reread this when I do. Any suggestions for a cool project for an ABSOLUTE noob?
acaz93 in reply to Scissorman6 years ago
For Beginner , I recomend this THis One ,
And this
Brennn10 (author) in reply to Scissorman6 years ago
I suggest buying the book, "Electronics Projects for Dummies" All the projects use breadboards, and the projects give you a list of all the parts, and a step by step instruction, on how to go about building them. It also has lots of pictures which helps a lot too.
bobbyrae in reply to Brennn104 years ago
I have read through that book, I believe that Earl Boysen is one of the authors. It is a good book in regards to breadboarding. Another book I have, which I like even better for this is Circuitbuilding for Dummies by H. Ward Silver.
Scissorman in reply to Brennn106 years ago
I have this book. It's great although I need the version called 'Electronics for F**kwits.
Brennn10 (author) in reply to Scissorman6 years ago
Is thata joke, or an actual book?
Scissorman in reply to Brennn106 years ago
It really should be a book. Unfortunately it doesn't exist.

The Radio Shack breadboard pictured in step 3 offers a unique teaching opportunity. Unlike the more common style pictured in the intro and step 2, the cheap RS model uses a sticker as its underside. Peeling that sticker back will reveal the horizontal and vertical buses, a picture of which could be very instructive.

Wooo!

Breadboards are the best, they save a lot of soldering time. The absolute BEST for prototyping and debugging!

I'm using two breadboards right now, and I'm so glad that I have them as my nice little pets.

You might want to make a note; BREADBOARDS ARE NOT EDIBLE, unless you really want to taste them =P
Brennn10 (author) in reply to T3h_Muffinator6 years ago
Well breadboards have been new to me the past few months. If you want to add to it, I can make you a collaborator. You probably can add some more info on the circuit making etc. etc.
T3h_Muffinator in reply to Brennn106 years ago
I wouldn't be able to add something for quite a while (I'm super busy, unfortunately, with school.)
PocketSized says: 6 years ago
I remember when I first started electronics (not that I'm anygood now). I'd never even touched a resistor but decided to buy myself a breadboard just for the shear excitement of it, needless to say I was rather simple minded and it didn't take long before the breadboard stumped me... lol, what I would have given for an Instructable all about my new mystical 'thing' that I had brought. nice job.
Brennn10 (author) in reply to PocketSized6 years ago
Im glad I can help : )
