Principles of Schematics

[@TimJC513]

I can vouch for this. They taught me everything I needed for a project I was working on. Thanks for the time and effort.

[@ericapelz260]

This is a great demo. I would mention that this technique is great for breadboarding very small circuits. I like to keep a highlighter handy as I breadboard a circuit and highlight the connections as I make them. This really helps to prevent missing connections, especially if you happen to be called away in the middle of it.

[@allwynaltron7695]

hello

[@Asyss_Complex]

Great tip!

[@allcatall3931]

he doesn't seem to enjoy it that much, which actually makes humanly sense..

[@satyabanukil779]

Sir I am an old man of 57 years but keeping immense in building electronic projects at beginners' level. I watched almost all of your presentations and request you to kindly show us in making a veroboard project based on schematics i.e. how to cut the lines and solder etc. Regards, Satyaban, India

[@AJmnz89]

Thank you, Ben! Your video is a huge help in understanding what an electrical schematic looks like in real life.

[@xanokothe]

I do computer engineering, and I understand everything you say, in every episode. Thanks for sharing with us!

[@LinuxManScott]

If you are serious about learning electronics heres a great series on introduction to electronics. It's a long series (about 8-9 hours) to watch the whole thing but definitely worth the time for beginners with a desire to learn but don't pick up quickly.

[@CARBr6]

Excellent, EXCELLENT video! I have been looking for a video that will really explain how to decipher a schematic. Being able to watch you go through the schematic and connect it up has really helped to make it that much clearer! Thank you.

[@dawdandong7479]

ya gud I love d videos

[@wiinick90]

A transistor basically takes a tiny electrical signal and opens a gate for a bigger electrical signal to go through. Hence the 3 pins. In/Out/trigger. And ground is like the end of the circuit. Like a battery, + and -. The electrons flow through the circuit, and back into the power source. Electricity cant just go nowhere, it needs a direction. From one end to the other.

[@el3vil]

is a pleasure to see your fantastic videos and remember, those college days burning circuits ... a big hug!

[@smooooth_]

This is the best schematic/breadboard tutorial on the Internet

[@chillacombs8790]

great presentation ben...simple and to the point.am an electronics hobbist and is quite fascinating watching your demos...big thanks papa

[@allbunsglazing]

If the content wasn't so spectacular, I'd be pissed about that advert :)

[@kr5746]

+Sam Murray (AllBunsGlazing L12) RIGHT!!! Good thing Ben is iteresting and easy to follow and understand, or else I would "click it off"!

[@vimicito]

Eh, it accurately represents most project managers and meetings (:

[@joren040vc]

here is a tip for the PNP transistor the arrow points towards the line or a smal plate so that makes Point Near Plate or PNP

[@Bush09Lots]

what a great show... thanks for taking the time and effor into putting together such a professional product

[@Dee_Just_Dee]

As for the user question: One particularly good use of an obsolete cell phone (certainly one with a half-decent camera and a microSD slot) is to download the DailyRoads Voyager app onto it and use it as a dashcam.

[@Aadiboyrocks]

hey ben your video's are really help full ! i am new to electronics and was wondering Which electronics components should I always have on hand for my parts bin ? thanks a 13 yearold aspiring hobyist from india

[@nicknormando4220]

Man this made schematics make a lot more sense. Thank you!

[@Aerox90]

I came up with a smart way for remembering which of the NPN/PNP transistor-symbols is which: NPN: "(N)ot-(P)ointing-i(N)" PNP: "(P)ointing-i(N)" (...plus a "P" at the end 😅)

[@llloyd4]

There you would need to know some bits of data and use one of the founding formula, E=I*R , Voltage = the sum of Current times Resistance. So if you have an LED and you know it can take 50ma and your going to use a 5v source, with some basic formula manipulation it would be 5v / 50ma or 100 ohms. :D

[@61mab]

Thanks, still have my breadboard but it was Dos days when I went to Tech school and that info went in one ear and got pushed out the other by time and irrelevancies. I still have my books though so maybe I'll give it another go with some simple circuit, The sad thing is we don't have the electronic stores that you could find all those components in racks with bins, at least in W.L.A. Funny that I still have my last project on that board but I don't remember what it was. I had a store and was repairing medical equipment that was in some cases housed in wood! It was solder days, then progressively became micro and modular.

[@sheharyarahmad7078]

Same over here

[@FrancisRGarced]

Thanks so much for all the great tips

[@khawk7365]

How do you find out where to connect the positive side of the battery if it does not show it if it only shows the grounds? For example if there's six components connected to the top rail does it matter where you connect the positive voltage in?

[@gallimead]

Ironchristiano21. I was taught in Liverpool, but now residing in Ohio. The answer is yes, the us, uses the slighter older component symbols, especially for basic components

[@draakenwraak]

Still I want that you make your own game console. You are smart enough to do that so please make it !

[@kiwanoish]

As a beginner, I've always found the concept of ground a bit confusing. Sometimes there are positive, negative voltage and ground; Sometimes, like here I guess, ground means the negative pole of the battery right? Sometimes it's chassi ground. How do I distinguish between them, and why not just say positive and negative instead of positive and ground if that's the case? Or am I confusing things?

[@KuraIthys]

Yeah... I think that's asking a bit much. I mean, in principle if you had the time and patience you might be able to hack together something relatively primitive using microcontrollers and FPGA circuits, but even then you'd probably be using a lot of pre-made parts to get anywhere near to it being practical. I've seen prototype boards for FPGA chips that are relatively easy to work with. (one even has sample programming for VGA output), but it's a huge task even then...

[@deserty7883]

This is something that I have been looking for a long time, thank you ben! I am looking forward to see if you continue to do this, but can you do a video on a basic "start up kit" of sorts for people just getting started in electronics.

[@ConradvanderMeer]

There are 2 standards for electrical symbols in use, one is the 'American style'the other is IEC wich indeed is using the box symbol for resistors. Unfortunately this is not mentioned at all. A lot of the schematics found on the web use IEC.

[@soulfuldevil]

I heard the words "Flip-Flop" and it made me immediately think of a Minecraft T-Flip-Flop. And from what he said it sounds just like it, which it probably is.

[@richb313]

When describing current flow through a diode you state the direction is towards the point of the triangle. This is actually incorrect. The holes flow in that direction but the electrons move in the opposite direction. Electronics Engineers are taught hole flow, or the spaces the electrons occupy. Electron flow however makes more sense when actually working with electronics. .Still we mostly consider a positive terminal to be hot when the electrons are supplied by negative, usually ground.

[@artchap2861]

What applications can learning this lead to? I jumped in the schematics randomly on youtube and im not sure what it can do. this seems pretty easy but idk what it even does.

[@31337flamer]

with an opto-element or smth else u can use the vibration circuit on old cellphones.. send sms to the cellphone and f.e. control smth or start smth that is far away.. just put a 5$ sim card in it and u are rdy to go... when the phone rings the circuit can do smth for u..

[@AntPDC]

These symbols are US/ANSI. The IEC symbols differ in some respects, so if you are in Europe (and elsewhere), be aware.

[@darthgumby2406]

So according to the schematic, I can see where pins 7 and 6 are connected, but as far as pins 6 and 1, I see they are not connected even though there is a line going between them. Is this common that the line going across from power and the line going across from ground should not be visualized in relation to the rest of the circuit?

[@dasdew2]

No idea what the comment was, but I will say this. Lord Kelvin was a very smart physicist and engineer, he once declared that a "heavier than air machine that can fly is impossible" Well the Wright brothers didn't get the memo, and they attached a motor to a glider. You want to talk about impossible? We live in a world where a lot of everyday things were once called impossible and the man who made them were called insane.

[@rhythmandacoustics]

Is there any more schematics lessons such as what is the volatge of such and such components, etc. What occurs if this is open or short etc? More lessons on semiconductors schematics and troubleshooting?

[@DoomGuy9001-MK4]

In the UK the resister symbol is a rectangle. Just letting people now that is all.

[@martinkuliza]

Interesting, thanks mate, appreciate that knowledge, thanks for sharing, i didn't know that

[@vapormermaid]

it's more consistent than drawing zigzag lines

[@robertw1871]

A lot of guys over the pond use the rectangular symbol as well, it just looks cleaner to me, started using it probably 20 years ago after seeing it used on a schematic that was drawn in Australia... Just like the metric system, we are slow but will adapt eventually lol, might take hundreds of years but we’ll get there eventually...

[@living69nightmare]

how would you know what size resistor to use if your making something yourself and not going off a schematic?

[@sailor81]

Thanks! I can make circuits but can't read schematics very well. This helped me a lot

[@ldsframeworks]

Just wanted to say thank you dude thank you.

[@Lemonlickerz101]

Hey ben, could you build a controller, PS3 or Xbox 360 with a LCD screen in the middle controlling the controller features and digital buttons that could change into buttons you want it to be. hope to see you build it!

[@TheVideoVolcano]

what role does the 555 timer play in this circuit? You can make this sort of thing without one. Anyone explain?

[@7cleverboys]

ik im late but im guessing that it just makes a suqare wave for the transistor

[@Dee_Just_Dee]

That's right, a 555 gives you a nice clean on-off from your RC timing rather than the RC circuit's own charge-discharge curves.

[@lpoiy]

How do you determine the right capacitor for your needs?

[@TheeAbstractHero]

Could we use this to make the pressure pad thing ben made a while ago for his bathroom?

[@NicholasAarons]

Awesome Video Ben. Keep up the great work. Nick.

[@diddlydevil2846]

It's possible, but... 1) you would have to guy out your xbox and replace a ton of hardware. 2) Microsoft would probably brick your system once it caught on that you were using invalid discs. 3) PS3 games are coded for PS3's only 4) PS3 games are on blue ray discs, Xbox uses DVDs So if you did rig your system to play PS3 games, you'de basically just have a PS3 in an Xbox case

[@johndbumpus]

Thanks, your videos are a great help to my understanding.

[@loganjhennessy]

What is the function of the 555 timer in this circuit? Couldn't the same thing be accomplished without it, as long as there is a transistor in there somewhere? Great video, thanks for posting!

[@jedver242]

I plugged this schematic into every circuit in an attempt to garner some understanding. What's throwing me off is my grounds. My voltage source starts positive with all ground connections equaling the negative. Am I assuming wrongly?

[@pratherat]

Is that an old Techtronix scope on the rack behind you? I have one of those!

[@BastetFurry]

You should have mentioned the EU symbols for resistors and condensators too at 1:30.

[@deltapparo4451]

Use a yellow highlighter to mark up your schematic as you make connections, then you know for sure you got them all. Just because all of your parts are used up, doesn't mean you made all of the connections.

[@Rapcom1]

I have a project I would like some advice on. I purchased a 9" tablet with a mere 8 gb of memory and I want to upgrade to a larger level of memory. I paid $20 for it because it was broken. So I'm not worried about damaging it. I fixed the damage and now I want to experiment with it. I'm limited on funds and I know buying one would be easier; but that is no fun and I won't learn much. What is the highest memory that I could upgrade to and how do I recognize what chips are the memory?

[@DonMuffatello]

Richard Potter I don't know rly how to do it, but this is definitely the wrong place to be asking, go on ifixit

[@ChrisPBacon21]

1:51 Are these US standard symbols because I study physics in the UK and these symbols are completely different?

[@Javierm0n0]

Liked this episode even though i can read schematics already lol. can't wait for the next one!

[@marcelferme3178]

Hello! For my project I use atmega328p-pu. And I don´t know if I need a 5v DC regulator if I have a 5v DC transformer (230V AC-5V DC). Why I need a 10 (or 100) microfarad capacitor if i use atmega328p-pu without arduino? Thank you and sorry for my english.

[@joshviles4970]

iv got a vid request. discussion on variations of components in relation to going online and buying what's available opposed to being a picky buyer who only buys necessity. ..I'd bulk ebay (setting: I decided to go and buy some parts to play with. and realized a resistor pkg rated at 1/2 ohm and finding there's a bunch of others between it and 3ohm)

[@baruchshad3203]

can you connect the 100k ohm resistor from the positive rail to pin 6? if pin 6 and pin 7 are connected it seems the same to me? would it connecting it to pin6 cause issues with the 10uf capacitor that is also connected to pin 6?

[@jeffrey123666]

with pleasure

[@tHaH4x0r]

You put in a photodiode but not a comparator or opamp in the most used component list? I can assure you that there are waaaay more circuits using opamps then there are circuits using photodiodes

[@ThePettreable]

Hi. I dont know if this is totaly within your line of work. but... In my line of work i use a fullface gasmask/dustmask , and after wearing it for some time while working it gets kind of warm in there. so i was wondering if you could come up with a way to keep the mask cooler inside. through the filter or something. or make a piece that goes between the filter and mask. the mask has a standard industrial 3M connection. I also have an Military grade gasmask(just for fun) standard NATO filter :)

[@greenbeginner3353]

Can you do this video with free wires instead of the “breadboard?” It hides everything and I have no idea what’s going on. I don’t know any more than when I started the video except the symbols thing.

[@albiiiiii_]

Ben, you're teaching better than my science teacher XD

[@crawdini7641]

That was VERY helpful. Thank you .

[@eugen9611]

what is the 555 thing? and what is that board he is using?

[@ten132]

Missed it by that much!

[@347thekid]

Ben, thank you for all the great videos you post, but I am a beginner and I am having trouble understanding the connections to multiple components. for instance pin 6 and 2 connecting along with R2 and C1, I just can't seem to understand the multiple connections. Pin 1 to ground no problem, pin 8 to pos 5 volt, no problem. Do you know of any other videos or books that can help clarify this confusion for me. Thank You

[@mephisto2468]

Hi, great video. Enjoying all your videos. Thanks!

[@TechHackerKa]

i wonder what the capacitor on pin 5 is doing. i thought on 5 would be an constant current which shouldn't be needed in this example. could anyone please explain that to me :)

[@krypticmac]

the photo resistor looks like an angry face with lighting shooting out its eyes lol.

[@EfrainMcshell]

Do you think you can make a better closed up to the bread board please?

[@dingo1812]

Wheres a good website to get reliable schemmatics from

[@dawidpiwowarski1912]

4:47 wtf

[@Abdousjh]

😂 😂

[@darthgumby2406]

I have a lot of trouble visualizing from schematic to breadboard. Any tips to help me out? Even this video is confusing. I understand what Ben is doing, but I just can't wrap my mind around how to interpret such a large schematic to a small breadboard.

[@darthgumby2406]

Ok, I figured it out after some more practice. One baby step at a time

[@logictechratlab8787]

use a program called fritzing. reacreat the schematic and it will be autotomaticly on a bread board so you only have to connect the wires like you see them on your screen

[@BigManko]

Could you do a camera-related project? That would be awesome!

[@latzobear]

shouldn't the schematics have dots in it to show that the wires are connected?

[@allanmacuser]

thanks for the info allan in the UK

[@Falney]

Can you substitute 1x100k resister with 10x10k resisters in parallel? I am not saying I would or asking if it is reliable/efficient, just asking if it is possible on a mechanical level

[@TheVideoVolcano]

Yes, indeed you can. This is done a lot purposely by motherboard and power supply manufactures so that they have backup caps instead of one big cap that would stop computer working. 10 caps gives you 10 fail chances. Capacitance just adds up.

[@notanimposter]

No

[@david52875]

Falney You would connect them in series.

[@5zalfn]

Ben if only you were my lecturer. I would already be smart years back then :D

Hi, I like your video. Thanks

[@travisbooth4808]

by the way you got a new subscriber

[@Stephen-cm3fs]

Thanks for the video. Quick question about current flow. Even though most schematics use conventional current positive to negative isn't true current in wire circuits going from negative to positive?

[@blakemartin2785]

If by "true current", you mean the direction of the flow of electrons, yes. In visual representations, it is an agreed upon convention to indicate the direction of current as the direction of the flow of positive charge.

[@Stephen-cm3fs]

Thanks for the reply, definitely appreciated!

[@latzobear]

is there a link to the schematic

[@Furby_assassin]

Great as always!

[@ernest747]

finally someone who explained it normally

[@layeraddict]

Thank you very much for this video,very helpfull !

[@TheStiepen]

Your definition of diode current direction is misunderstandable. probably better is to say: the positive connection needs to connect to the triangle to connect. Also, regarding resistors, in some parts of the world a box is used instead. for capacitors sometimes one side is thicker, thats the negative part. Also, note on wire connections in some parts of the world you don't need to mark non-touching wires. Instead you make a thick dot at the connection point

[@Spiralexe]

nice work ben iv always enjoyed your videos keep up the good work :D!
