Schematics are the functional diagram of electronic circuits. With so many designs available on the web, understanding how to read schematics can unlock a world of possibilities for the electronics maker. In fact, if you can read a schematic, you can build a circuit before even understanding how it works! - Jak na to + styl
I realize this video is 11 years old, but I still wanted to say thank you. Thank you for not assuming too much, for explaining it simply and clearly. And for anyone reading this who is trying to teach themselves electronics but is feeling intimidated, keep at it. You CAN get it. Don't be afraid to make a mistake, you will burn up some components and release the magic smoke, but before you know it, things will start to click and it will start making sense.
Collin: Thanks for sharing. You and others like you have helped me pass my truck coach exams. You have helped me provide a better life for my family and for that I thank you. Keep up the good work.
Hi Collin! I've just started learning electronics, and thanks to you, it's becoming a lot less intimidating. Thank you for all that you do. Your videos are excellent. Cheers!
Fantastic explanation, I like how you focus on just a few core elements and give the audience time to absorb the lessons.
This helps A LOT to those of us who wish we could do half of what people like Collin can do, but have no idea where to start! It has always been something that scared me, but him simplifying and explaining each of these things makes them seem kinda easy.
I love how you simplify everything. Your tutorials make my brain swell like a balloon.
Gosh that man must be one of the most rated teacher of all times ! God knows how well he explains things !
I just started reading Make: magazine and saw some schematics. Even though I didn’t plan on building the project I still wanted to know how to read it. So thankful for this video!
I'm just getting started in Electronics as a hobby. I am really enjoying your videos, thank you for making them.
Same sir
Me to
I love this Channel a lot. Its very informative and Collins make sure the viewer understands the subject discussed in the video. Keep it up ☝. Thumbs up. Love watching every videos you make.
I look forward to your every video, Collin. You certainly have a gift for teaching. If I had a teacher like you back in college, I might have not gone into Accounting.
Watched in slow motion to take notes, I LOVE YOU MAN
A true testament to Collin's great teaching and videography skills:
Every Collin's Lab video has at least (if not two) one top comments that call for the return of Collin.
p.s. Collin come back. we all miss you.
It may have been helpful to note that an IC has a dot in the "top-left", or where you would start counting pins on the physical piece.

Object lesson in the idea of not knowing how much one does not know. I didn't think I was going to learn anything from this vid. I did. I suspect now that if I were to re-check a 3-watt amp I made, which ended up distorting badly, I will find that they are all backwards.
I very much appreciate your comparing the look of schematic symbols to their real-world components. I've always thought that was the best way to learn them. Well done.
I'm loving these. Stumbled upon them from the electronics intro Maker vids - but this guy is a legend. Lovin' it.
I think I just found my inner nerd... Throughout the whole video, I felt so excited to learn about all of these. Thanks for this.
Collin should have his own channel for his lab videos, he is the reason I've watched half the Make videos.
I work in electronics everyday and I still learned things. Great vid.
I love your video and your pace/cadence of communication. I was hoping to see the inductor symbol explained before or after the capacitor.
Thank you so much for this! Finally someone to explain things without his audience falling asleep.
Collin creeps me the fuck out but gives me so much knowledge at the same time.
It would have been nice having something like this when I was a kid. I had to come up with my own allegories. Good job! I like this video.
Learned more in 5 min than I did in high school about diagrams. Maybe because I was interested today :)
You're awesome, love your simplistic method of explaining complex ideas; if only more lecturers had your flair!
+Fluffykiwis J hi everyone ,if anyone else trying to find out how to make electronic circuits try Elumpa Circuits Expert Alchemist (just google it ) ? Ive heard some great things about it and my co-worker got cool success with it.
Thanks Collin your video gave a detailed explanation for electronic schematics. Awesome job!
Nice set of videos! One thing that makes diodes and transistors easier to understand is to think of positive current. Have you done a video about that?
wow this is the clearest explanation of schematics i have ever heard!
really smooth and nice editing! really great job!
Loved it! How about a nice follow up video with more detail. May I suggest the bandpass filter schematic used for the background. Possible tips in follow up: Explain how the virtual ground connects, How & where to save ground connections on a breadboard, how the schematic directly compares to breadboard and PCB. I think many like my teenage son would gain a better understanding of this information with your methods of teaching and demonstrating. I will keep watching for more tips and ideas!
I miss projects from collin. these are great
anyone know what kind of vice he's using in this video? I'm looking for one like that...
Collin's Lab was the only reason, why I subscribed.
Awesome vid! I finally understand how to actually read schematics now.
The test signal circuit only one hook or all of the negative output ?
I do think, when talking about electronic circuits and schematics, people should get comfortable with the conventional current. Even though it is a scientifically incorrect way in looking at the electron flow, most of the, if not all, schematics are drawn having conventional current in mind. I remember first learning about this in school. Pissed the hell out of me. When you're dealing with + and - in the circuit, it really is not a big deal, but once common grounds and power supplies come into play, I just found conventional current to be more useful when reading schematics.
Another point in favor of this: current isn't always carried by electrons -- in stuff like batteries, current can be carried by actual movement of positively charged atoms. So it's usually best to just think in conventional current ("net movement of positive charge") instead of worrying about what subatomic particles are carrying the charge. An electron moving left is totally equivalent to a hole moving right, for the purposes of circuit analysis. So IMO, talking about electrons during circuit analysis does nothing but confuse students.
I'm just now getting into electronics and this makes learning about it so frustrating.
Another thing to note when reading schematics, is generally signal traces run left to right, and power traces run top to bottom.
Can you please make a video how to make a schematic for etching from only an electrical schematic? I'm having trouble with drawing one from it.
@rydude998 If you are talking about two-color diodes, these are actually two diodes wired internally in parallel. So, no matter which way you try to pass current, one or the other of the diodes will conduct, getting, say, red light in one direction and green light in the other. (By quickly switching directions, your eye sees two colors at once, giving, in this case, yellow.)
This was incredibly helpful. Thank you.
Ey, any simple program to draw schematics?
Thanks.
@3Deity I am not so sure you were wrong. Collin's explanation is describing electron flow, conventional current would flow in the direction the arrow points.
haha dude you are strange and very different but thats why you make learning extremely fun and easy. Just want to say thank you, keep up the good work, and most importantly dont change because if i had teachers like you in school i would actuallly have learned stuff while enjoying it.
Thank you so much. You make me to understand very well. I have job interview. You r very helping
i love this guy collin you are the man,wish you can teach me how understand circuit board,and how they work.and understand more.if you could
Awesome video for beginners! How much time you spent planning and making this video?
Grate video but are you agent Smith from the matrix?
jajajajaja maybe :V
I think he was going for a Jack Kilby look
Everything that has a beginning has an end neo....
You can choose the red resistor or the blue resistor
thanks for the video..
@rekinu5 That's Ground (GND). It's connected to Earth ground, digital ground, or the negative side of your supply.
Excellent video. I like the no bs approach.
Cheers Colin! Your a legend! please dont stop making these vids!
I'm wondering what the schematic is for at the end!
question. What software is used to create those schematics?
I got quite confused there, because electrons move in the opposite direction from current. Sooo... when he said that electrons move through LEDs the way he said that they do, I am not sure if he was actually talking about electrons or about the current(which I think he meant to say).
Could someone please help?
What about that ground thingy or earthing or whatever that three line that looks like a triangle pointing downwards :/
?
thank you for this useful video,,, hope to see a video of how to determine if the shematic is working,,
I know all the basics but how do you know what a circuit is supposed to do just by looking at its schematic?
nice i am the one who chatted with you of facebook and this is great to help me out sometimes.
I really liked this video it's quite good. A lot of the stuff would only make sense if you took physics but it's still a great video (IE capacitor parallel plates). The only downside is that actually analyzing circuits gets waaaaaay more complicated, especially when you start getting into non-steady state stuff and using the calculus.
I'd love to see a video about the different methods of determining voltage drops, amps, power, etc etc. Like using KVL, KCL mMethod, mesh node.
Very nice! I will be placing a reference to this video in a video series I am creating.
HOW DO I DOWNLOAD THIS ? AS I M VERY KEEN ON IT.
La verdad es muy educativo el señor collins,saludos chicos
Thank you for explanation.. very easy to understand
maybe I'm late but the music in the background was exactly what I needed this morning
music page?
@keithosmarferrer It is in reverse right?
thnx Mr.Collin you deserve every like and subscribe
But how do you read them? where do you start? left to rght, top to bottom, right to left?That is what I want to know and he did not explain that.Does anyone know? thank you.
I was wondering if circuit boards can be used to help feed L.E.DS
@number0IX Yup, right on. In fact, many LEDs have a relatively low peak reverse voltage specification. Most of the ones I use are rated around five volts, IIRC. If you push them too hard in reverse bias, they *will* fail. It's not an LED if it conducts in both 'directions'; that would be a light bulb, neon bulb, or other device where polarity doesn't matter.
@modgemtb One end (the end of maximumness) goes to the signal/voltage source. The other end (of minimumness) goes to ground or the return. The center (the wiper) is connected to the circuit that is being fed by the pot. When the shaft is turned to some point, the wiper is positioned at some voltage point between that of the source and zero. Pots have power ratings and the current drawn from them must not exceed them, which is not usually a problem for signals like audio or small DC controls.
how do you wire up a potentiometer?
Where do you start on a schematic
can you please keep explaining more about schematics its really interesting
Colin was talking about the orientation of the diode in the circuit schematic, not the direction of charge flow in the diode. Charge flow goes from the anode (negative end) to the cathode (positive end). That's another thing, Colin mistakenly called the negative end of the diode the cathode. That's the anode end. Any device that dissipates electrical energy has the cathode end being the positive end and the anode end being negative.
Great Sir I loved it
please could you also tell me the rep of photo diode
Thank you. Very much you explain slowly and step by step and also the function😊🙂🙂 thank you...4x
Great as usual.
It would be more helpful, as if there were some links in the description for Fritzing and other free/open-source CAD applications.
is there any body who worked by ADS131M04 i want to design the schmatic but actually i don't know from where i should start!!!
Collin vid showed in subscription notice. WOOT! Collin for president.
Thank you. That was every so helpful.
Whats does mean F.P on a resistor like an example 47F.P
What's the 3-lined arrow looking thing?
Great video as always Colin. The only thing which could have been improved is the diode section, which very quickly brushed over the fact electrons flow from negative to positive and not from positive to negative as was presumed.
You weren't wrong in what you said, just that it could be a point for confusion :)
What about when the lines cross and there is what looks like the top wire "jumping" over the bottom.
Electron flow and hole flow exist in BOTH PNP AND NPN transistors and can be used to explain either. Pedants talking about electron flow and insisting it goes one way or another should remember that these are metaphors and cannot be considered "reality" since Quantum Mechanics rule here and the fundamentals of Quantum Physics say that an electron (or other fundamental particles) can exist everywhere at once i.e. they can (in theory) exist in two places at the same time.
whats the name of at the program?
I now want the big schematic as my desktop!
@GegoXaren I live in Argentina and we also use the squiggly line, everybody does, in fact I don't think I've ever seen someone use the rectangles. For me the squiggly line is much more representative of what a resistor is, like most symbols, the rectangle lacks character, it doesn't imply anything.
is there a playlist of just collin?
where can I get my parts in canada
Does electricity always flow from negative to positive? If so, where? Thanks a bunch!
I wonder what kind of software he is using to create those beautiful schematics.
@Yvessam The flow of electrons is the opposite direction to the flow of current.
What editing software does Collin use
Very informative.
This video is quite helpful.
what is the program to make that beautyful schematics?
Still don't know what to connect to the +X V point when i have no idea where to connect the bloody ground and the circuit diagram has no ground terminal.
U still having problem understanding? Maybe i can help. Been working in electronics for over 50 yrs
Another great video. Simple, informative, inspiring, and effective!
Does the freak-world style help demystify electronics?
@rydude998 LED's do not allow light to flow in both directions, this is why they have one big leg and one short leg. Current can only flow one way.
Awesome video. Thank you!
