Best explanation video from you ever Paul. I never learned electronics but made it as a hobby since 20 years. I draw my circuits exactly the way you explained. I never knew there was a „best practice“ for it. Now I learned something. Thank you.
Great topic here as i couldn't do or test my projects without a good schematic to organize my thoughts and debug (most evident on my current meter/logger which was a LOT of different components). Helpful bit of advice: always (or get in the habit of) using the "loop" method for any crossed schematic lines logically not connected. This makes a better distinction what is connected and what isn't. Happy Friday!
Hey everyone, the greatest success that I have ever had was with the Gregs Electro Blog (just google it) definately the most helpful info that I have ever tried.
Hey Paul liked this video on the schematics,very helpful. I'm still new to electronics just got into this about a year ago. I've learned a lot by watching your channel. keep going and thanks.
Great video, as a newbie I found this very useful. I have started to learn at a mature age (57) and have found your videos very interesting and easy to follow. Could benefit from more videos on schematics understanding and reading them, me that is. Looking forward to each video you do. Thanks again. Tony
Great explanation Paul, I definitely need to work on my drawing of schematics. I have a bad habit of doing a kind of shorthand notes on a project and never going back to draw up anything that's readable by anyone else. I definitely needed the refresher. great video paul and you have a great weekend.
5:44 Thanks for showing how to connect or jump an intersection. Lately, there have been some folks obsessed with so-called rules that say never dot an intersection.. only use T connections. Yours makes sense. 👍
You labelled C2 as 0.1 μF, not 100nF. Is there a reason for choosing this notational magnitude? I can imagine stating component values in the same magnitude for a given circuit makes following the circuit simpler, but is there a convention for this? Or should we just adopt whichever approach we personally find most convenient?
@@AThreeDogNight It's not a matter of conversion, just scale. Like dimensions being all given in mm even though you may encounter 5mm, 5cm, 5m on the same project they are most commonly given as 5mm, 50mm, 5000mm on plans.
9:18 I must be misunderstanding something here. Shouldn't pin 2 be on the other side of the normally open momentary switch? Is this an electron flow vs conventional flow thing?
When I started we used draughtsman's pens and thick lead clutch pencils, sharpened in a variety of ways (point or straight/angled chisel) with a small penknife. which were expensive for apprentice pay but guaranteed crisp lines (important for exams). By my second year rollerballs emerged which cost more than a standard ballpoint but were much cheaper, and easier to use than the draughtsman's pens. and a selection of 0.3,0.5 and 0.7 propelling lead pencils which produced perfect lines and never needed anything except more leads (I still use them). At work we used stencils to ensure standard sized symbols but in class we worked freehand for speed. In telecoms (strowager) we would box diagrams to keep voice switching and control separate so the serious diagrams could be 32ft long but if you knew the steps you could quite easily find the elements you needed to follow. Over time the diagrams would be coloured in so they looked like road maps.
Different capacitors take longer to charge or hold more charge than others. In this case it sets the time between the on/off signal for switching. Bigger cap longer time on.. Or off not sure which.
Very good video Paul, I'm totally fed up with trying to make sense of circuits that use the lazy arse approach of shoving everything in little box's and showing it connects somewhere on another part of or another page. You can't see the big picture else - literally!
You mention in the video IC1 is a 555 timer yet don’t label it as such on the diagram. Also at 9:05 - no dot! So is C2 connected to ground or not? Great video but for people new to electronics these things matter especially in an instructional video. I love these videos so please keep making them!!! 😁
thats a nice drawing paul. to improve draw use pencil and rubber eraser , it also helps to understand better circuits and some mistakes that may occur. I tend to use the jumper wire between crossing wires and avoid a blob of ink doing a node :D Thanks for the nice tips. Optional keep a date to keep record of you're progress.
Hi Paul, thanks for the video. Quick I learned the basics from your video. My question is what software is there were I can create schematics? I know Eagle, Kicad and LT Spice but I need something more basics with can clearly represent a power supply, a terminal block, a consumer PCB (a PCB microcontroller). Please let me know if you can recommend something. Otherwise I will continue with Paint or Office Excel since I can draw lines as I want to but it will never be professional.
Hi Paul, thank you for your willingness to share your knowledge with all interested peoples. I however am in a stage so not ready for this, sadly lost off the blocks! This is why I have opened up your video, I have been looking for anyone willing to work with me on a prototype I have been working on and am at a spot in building it that I need the services of someone with your kind of knowledge, a electronics draftsman. I need someone willing and capable of drawing me up some blueprints for my prototype so that I can advance this idea I have and I am just taking a chance of shot and dark hoping that you might be willing to point me in the right direction any help would be greatly appreciated thank you so much I will patiently await your response

Search for electronic components, note top 10 types(capacitors, resistors, Diode,.....) google about each one, and how they are represented with symbol, once you learned this enough trust me you can understand any circuit just by looking it....

@@timstoriger3927 Components can be bought online and so does the pcb (you can order by uploading required files, this doesn't cost you much) the important thing is connecting the dots together and making a wire diagram and schematic, if you think you've made once you did this, hold on what's a dummy body for without the brains? that's right, coding the device to work as intended with all the required drivers is equally or more important than the hardware. before making a device research if the device is already existing if not any similar device. because if you can find a nearly similar device with some components it's only matter of adding additional modules. but important thing! coding, so focus on learning C, C++, embedded C.

@@thejeswarreddymula8786 Thank you for your answer. Yes, programming is important and several years of training in electrical engineering and a good understanding of science are important if you want to develop something. I have an engineering degree, but not in electrical engineering. But my goal is not to actively develop and program something. It's more about being able to work in technical purchasing in a large corporation and understanding what kind of assemblies you are buying ... I do not need to understand any program code as a third party. Basically, I just want to focus on how I can acquire the necessary knowledge to understand complex circuit diagrams and then to be able to recognize the devices and functions that are implemented in this circuit diagram.
You should direct this at the Chinese electronics manufacturers. They lable nothing and shit is all over the place.The acetone their IC's also so you cant get a part number.. it's dumb
i appreciate this video being out here to help people, but as a student this was not all that helpful for me, and im still having trouble reading tthe circuit board and drawing my schematic
@@MrGiedriokas Always a nit picker in the group. Look when you draw a real diagram up you put the pins in place on paper to follow the formatting rules not as they actually are on the IC, Some referance the IC (usually if they are complex IC's) in the diagram as a block others break them down into sections with actual symbols (for simple amplifier and logic ICs).. In a service manual the IC's are referanced on another pack like he drew that 555 IC, That referance is for the pinout assignment of the real IC not the pinout on the diagram itself as that would be numbered pins which you can go back to the referance page and dechpher there along with voltages and signal levels on each pin and some data about the componet... See you'd know this is you ever actually looked at a non Chinesium schematic or service manual for a piece of equipment.. Secondly anyone with a bit of common sense knows this was also an example as well just like the entire video.. No need to nit pick everything someones does because he didnt have to do any of it, He could have kept it to himself or went the greed route and hid it behind a patreon paywall but he didnt.
@@Elfnetdesigns Jesus christ relax dude, I thought it was just funny that he said to do it one way but later done the opposite way, I seriously like his videos and very appreciate them, much respect @learnelectronics thanks for teaching us!!
Disagreement on Logical method 555. Logical would be to indicate the Pins as they are located on the IC. If the Op Amps are employing a Voltage Off Set or are bi polar the input/output voltage do in fact need included.

I'm not sure if it is a rule or anything but I have noticed that almost all of the schematics I've used that had 100nF caps were labeled 0.1uF.
There are conversion sheets online somewhere, but don't remember where.
@@mikeoliver3254 I wonder if it's a reflection of the most common capacitance values, or just generally deemed more intuitive?

Can you help me more on schematic drawings?
If I may ask ,How exactly do you choose values for the components like Capacitor
Different capacitors take longer to charge or hold more charge than others. In this case it sets the time between the on/off signal for switching. Bigger cap longer time on.. Or off not sure which.
Very Nice .
Excellent video!
Just wondering why the 555 pin 8 it to VCC instead of ground?
Pin 8 is positive supply voltage. Pin 1 is ground.
Really? This is a good spot for the southpark ALERT CLASS meme..
