Complete beginner's guide to using a breadboard

why was this reuploaded? 😄

🤔

So +- voltage is basically 2 batteries in series and can do the same thing by tapping the middle of 2 aa batteries stacked on each other?

Wait...what multimeter measures "the amount of current flowing"?

Bist du deutscher? Dein Akzent klingt mir irgendwie Deutsch.

DO NOT attach the battery to the strap until the other ends are in the breadboard already - it's not bad with 9v, but if those exposed ends touch, it can cause sparks and damage the battery. If you don't realize it's happening, a battery can catch fire in your hand. Similarly when you're wiring up ICs - do the power LAST. In the video you did it first, AND you had the battery connected. So that amp sat there powered up for a long time with no indication that it's happy. If everything else is connected, then you power up, you'll be able to see if things are working right and disconnect the battery quickly if they aren't. DO NOT wire up breadboards with the power connected, always power up after you've finished the wiring. With low DC voltages, you can get complacent about this and end up shocking yourself or starting fires when you work with higher powered stuff. DON'T get into the habit of working with live circuits.

Top notch explanation, much obliged.

maybe a stupid question, but since you say here that batteries are enough to power the breadboard for these basic cases, when do you think a PSU like in your DIY PSU video starts to become necessary?

in other words, both for safety and financial reasons, i'd prefer to use batteries initially (still a complete beginner). but i'm trying to understand the downsides? is there something to be wary of when powering audio circuits with batteries? also considering that apparently modules run on +12/-12, how are 9v batteries enough?

What is the purpose of the 1k resistor in the first example? Why is it needed before the LED in the circuit? Why can't you just run the LED straight off the battery terminals?

At the atomic level though... Elecity "flows" (even if one would actually say that it flows) from negative to positive

that thumbnail omg <3

So nice thanks

So nice thanks

you go to fast. what a horrible teacher

Probably a great video, did not watch it, sorry.

But I can't help thinking the the best guide to beginners for using bread boards is :"don't do it, just don't" ;)

If you are a beginner you are NOT going to be DESIGNING anything any time soon, so there is very little experimenting.

You are going to build something to some existing design. More over most beginners also want to keep their builds, I know I did and still do.

A bread board circuit is inherently unreliable, especially in long term. So unreliable that it often fails before you complete the circuit.

As a beginner you don't want to be trouble shooting poor and deteriorating connections when you have enough work in getting the right connection and components in the right place and checking that.

Bread boards are useful (but not good) for experimenting with real components if you anticipate a lot of changes to component values.

But if you are experimenting then you are not a beginner, you are designing your own circuits and if you are not doing that with SPICE you are wasting your time.

Once it works in simulation you may want to verify it on a bread board. Which is ok, because your final goal is something better anyway, a Vero board build or PCB.

The structure / construction of a bread board is such that almost invariably some components you use have wires that are either too thick to fit or too thin to make reliable contact. The impedances and parasitic capacitances and inductances make them unsuitable for many circuits. And their piss poor current handling capability is notorious.

Today, if I want something NOW then I will do a Vero board construction.

If I can leave it till next week I will do PCB. At €20 for 5 PCB on my doorstep in a week, I can't beat that.

Think about, that is less than the price two hamburger meals here in Scandinavia.

It is not worth my time to spend three hours soldering or mucking about with a bread board when I can have a nice, reliable , professionally made and most of all 100% correct (meaning matching the schematics) PCB from China.

And some suppliers (JLCPCB) even assemble some of the SMD components for 'free'.

Which is an other great point as first of all SMD components cheaper but also increasingly some components are only available as SMD so with bread board or Vero you will need some break out boards to be able use them.

But that is just my opinion.

Awesome, you have a great way of explaining things simply that others often skip over or make very convoluted. Keep going!

Very nicely done.

Warning, there are cheap and expensive breadboards. They look the same but they are not. Cheap ones use cheap connecting grips, which are not always making a solid connection with components with thin legs, typically with the very popular 1/4W resistors. Othe advise is to avoid any diagonal. Always right angles and limit number of crossings.

Hello sorry for question i get everything but not the thing with second 9V battery... So this or most ICs need 2 cell battery to have like "+" ground "-"? And what if i wanna use like one 12V battery? Or like 3x18650?

new sub will checkout a few of your videos to learn more thanks for posting :)

Excellent. Thanks man 🤙

This video is just what I needed. One thing that kind of puzzled me was how you hooked up two batteries. Could you just use jumpers to the other rails? Or is that bad?

VERY GOOD INFO THANKS....

I cant believe thus only has 42k views

I rarely sit through a 20 min video. You did a great job. Thanks.

Awesome! Thanks a bunch!

Would I be able to take apart an old bluetooth speaker and integrate it into my breadboard to make a mini alarm system. Have a IR/movement sensor on my breadboard and have it transmit a tone to my bluetooth speaker?

Can you make more like this? with like a progression to more and more complicated circuts and concepts?

I'm embarrassed by the fact that my brain was like "Oh that works like redstone logic in minecraft".
No no no redstone works like this. Who would of thought I was learning electrical concepts 10 years ago from a computer game.

Just fried my SM47. I'll try this again later.

Thanks

My LED starts in the off state. It does power on when touching contact to negative rail.. but its off by default, circuits don’t like me

Hey Moritz another quick question : do you know a guide where we can choose a multimeter for this precise use (audio) ?
Prices ranges from two dozens euros to a thousand, there are several classes.. it's very confusing !
And maybe a website where all of these components are available ? I can't even find one !
Thanks once again :)

Great Job Boss!
No ambiguity

what an incredible channel.

haha lecker die guten JA Batterien hhhmmm

I have a LM324N and thought this circuit would work with it, but it didnt. The simple inverter circuit had odd behavior. The LED would not come on unless pin 2 was tied to the Vcc- rail, or unless pin 11 was disconnected.

This guy is a Legend, thx 🤗

Excellent. Thanks.

PSA: be really carful with batteries as well, and never put batteries of different brands or different charge levels(check voltage with multimeter)in series. Also, make sure the wrapper isn’t scratched, so as to not accidentally short it. I have had a NiMH battery explode on me and burn my skin, I was pretty lucky it didn’t hit my eye. I don’t think alkaline batteries can explode, but they are technically sealed pressurized vessels, so be careful.

In conventional current electricity flows from positive to negative however electrons flow from negative to positive

Does this man actually draw the entire breadboard by hand??!?!

Very nice tutorial.

I have only one note: it is bad practice to do connections or alterations on the board with live power. Power should be disconnected.

In one moment of the video it is clear that you accidentally shorted two pins. That is common so the reason of disconnecting power.

I love this because many people (ME!) might be too afraid to ask about this basic knowledge. There's a lot of assumptions that everyone knows this stuff already. You have a great way of explaining WHY some of these electronics work, which gives me a better understanding how to use the tools to do what I want them to do! Thanks!

just bought the Om synth lab from Bastl and your video/channel is a super important ressource for me starting from scratch, thanks for your channel !

please making more basics like this if I found anything more like this basics video I promise I will give 10 subs in 1 day from me

❤❤

Can we just appreciate the amount of time he puts into his illustrations
