I'm a bored 79 year old looking things to keep my mind active. So, I bought a Raspberry Pi 5 and am looking at all the things I can do with it, besides just surf the web. :) TH-cam is an amazing classroom. Thanks for your hard work, you obviously love it!
Great job! As an electronics R&D lab technician I worked these circuits daily (a long time ago.) You nailed this topic! You obviously understand your craft and can "splanify" it. When someone KNOWS a topic, they can explain it well. Thanks for getting straight to your topic and making a very useful video.
OMG... How am I just now finding your channel. Love your explanation and practical examples. How you do your setup is how I believe most people want to do their LED wiring. Not overly complicated but allows for growth and versatility. LED strips are nice but not as versatile as doing your own wiring. You show great enthusiasm which is encouraging to the listener. Looking forward to watching more of your videos. Thank you!
This is a very important subject for my 1947 Ford Pickup truck. I'd would like to run running lights on my running boards. Thank you for you sharing Rachel. Miss seeing you on TV.
As a beginner project, I'm making a PIR/LDR dependent light with rechargeable 3.7V li-ion battery including charge/5V boost circuit board. I thought the LED part would be the easiest, but quickly realized it can get tricky. Watched a few videos. Yours was the most helpful in answering all of my questions. Thanks.
This was exactly what I needed as I prepared to add LEDs to my R2D2 and Mouse Droid before the big meet up. Well explained, clear, articulate and you don't get off onto side stories or information we don't need. Your drawn diagrams are so useful to help understand the wiring. I've shared the link for video to friends in the club who are just getting started in droid building. Awesome job!
As an electronics tech I found your tutorial to be a very clear and concise explanation of basic electronics theory Rachel. Yeah I clicked on the link to check out the cute girl but stuck around for the energetic and entertaining as well as informative lesson. Well done young lady, you are a talented instructor! Liked and subscribed
I thoroughly enjoy watching your videos. If I would have had you in industrial arts (electronics), I would have paid attention. Instead, I get to watch now. Thank you for your time!
Thanks for posting this video. It is helping me finish a project that originally started in 2006. Wow! how much time has passed. Anyway after being stored away I just pulled it out to reconstruct it and finally finish the LEDS. Also I am glad you mentioned the duds in a package. It turned one of the red ones was bad. Very helpful, thanks again.
I' have watched many videos on this subject, and while they were all helpful to some extent, this was the most comprehensive and easily understood guide for me. Thank you so much!!!
Excellent video! Very thorough, well explained and easy to understand. I will use this video to draw up my schematic to wire and install 3 volt LED lamp lights in my model railroad depot structure. Great job, thank you!
Excellent! Simply excellent! I watched a TH-cam electronics video recently that stated if you don’t want to do the math, just figure 100 for each volt you need to use. Don’t know if I trust that or not!
Thank you! My god I have been trying to find a video to explain this so I can add lights to a model train layout and every single video or guide I read or watched was insanely complicated. This is excellent.
This was an awesome video. You explained it all so clearly and plainly, no jargon. And those pictures help so much! I will be sad if any of mine die as they will be going in resin XD
I really enjoy the way you explain how leds are wired and voltage distribution. I knew some and learned more. Your enthusiasm is amazing. I just finished a project involving Lionel Trains, Erector build and changing from AC to DC. Had two combinations of lights, two separate 3mm yellow led circuits in series, then 5 mm Red/Green in parallel for signaling. I didn't see a way of attaching a photo. Thank you for sharing your knowledge.
Finally!! Straight forward, easy to follow along, readable diagrams, on point the WHOLE time and most all at no point did have to write down something that’s not explained to then go look that up. Amazing, thank you. I have two question… I’ve always wanted to start adding lights to my woodworking and art so I save all old electronics. Can you take resistors from those and use them? Also do you do a video on reading resistors? Thanks again
This is amazing thank you for explaining the different ways and what u need I have watched a bunch of videos and they don’t explain them very good .. so awesome job !!!!
Hi Rachel, thanks for explaining this very simply, I’m a complete novice to this & really found your explanation really easy to follow. Amazing work keep it up😃😃
Hey this is great. Fantastic domain knowledge about electronics, et al and polished TV skills to make an engaging, appealing, and well-paced presentation is a killer combination of skill sets. It's so easy to make this stuff too dry, or too goofy, or patronizing, or whatever. It seems to me a lot better than it used to be, but used to feel impossible to casually learn about this stuff from someone who wasn't dead set on coming across like a punitive, lecturing grandfather, and I'll bet that turned a lot of people off. (Definitely pushed me away from amateur radio when I was a teen, that's for sure.) So often in tech stuff, the people that get all the recognition are the ones pushing the bleeding edge of the field. Sure, that's important, but I think people giving an impassioned introduction to the basics have a much bigger impact on the world on a whole. Thank you for what you do!
Thank you! I think I finally understand the concept. A little fuzzy still on current and calculating, but you probably explain it in another video. Now to do some maths and figure out how to backlight this dashboard im building for my sim racing rig!!
Thank you Rachel from New Zealand. I am repurposing some old car headlights in to party lights. I am using 24 volt Blue and Red LED's and I was just going to series them on a blue circuit and a red circuit. But your explanation of a hybrid circuit with its benefits was excellent. I think that means it will also make it easier to introduce alternate sequencing of the two circuits, (you know so it flashes blue then red then blue etc) but I don't really know how to make it do this. Any tips would be great! In any case, you are a wonderful teacher and I loved your video. Thank you very much.
Really love this video. You make it understandable and fun to listen to. I'm doing miniatures and need to fix lightning for my mini homes so checked to learn some more. Realised I had this small led lights at home while doing it 😅
I learned a lot about LED circuits with miniatures too. I built a Frankenstein castle facade a while back and wanted to add flickering candle lighting inside and blue flashes in the laboratory.
First time viewer. I found the content useful and your process of sharing information relatable. So I subscribed to see what comes next. I gotta add though, I was working on something while watching and listening to this episode and looking away something about your voice seemed familiar to me. I figured it out by the end of the video . At times in certain phrasing, a few words sound a lot like the tones used in automated home audio setup which various manufactures use to set speaker levels. WooP! WooP! wOOp! wOOp!
There is another way to also tell, look inside the casing and the section of the LED that is larger is the negative side. This is good to know if someone cut all the leads the same length.
Good tip, i never heard any youtuber mention this other then checking the leg length but once you bend them they look about the same and it hard to tell, this is a fool proof way to know for sure. That being said you cant hurt a led wiring it backwards like an electrolytic capactior. ITs a diode so its just blocks the other way, up to a point, but that point most of us wont reach playing around with them, allowing too much current is what hurts them. I seen a video i think electrozap tried to put a diode to help with voltage spikes to protect a LED's or something simliar but more importantlyfound he couldnt burn out any LED with no matter what voltage his power supply applied to it, i think like 40v max. He kept it a a constant current, showing that high voltage doesnt burn out LEDs apparently, just high current does.
That's a great tip! 👍 When the leads get cut then I'm always looking for a coin battery to orient it correctly but it's much easier to look inside to tell the difference.
If I bend or cut the legs then I'm always looking for a coin battery to position the LED correctly so looking inside is a good tip. I'll add it to my routine! 👍
@@RachelDeBarrosLive The button battery test is great if the LED is still loose, not so much if a string of LED's have been soldered to a circuit board. 😜
Can you just teach everything about life? I've spent years trying to figure out the basics but no one can explain it like you for me to finally understand. Thank you for your video. If you ever work with filaments can you please do a video? I've been trying to learn how to light up my dioramas. Now I can light my first one 😂
Thank you! Love your video!♥ You can also, let's say, use 5 LEDs in parallel and only one appropriately dimensioned resistor. This is very practical if you are building a diorama with SMD LEDs (in parallel) and want to add more dioramas later. Each diorama has its own appropriately dimensioned resistor, but only a single power source. “As long as the correct voltage is used, a device will draw only the amperage it needs, meaning there will not be “too many amps”.” So, my dad (the devil may still punish him in his hell) was right. Thanks again! ♥
Bonza! This was a really nifty and clear video, thanks. You have some really impressive graphics. I gleaned a lot from your video. Salutations, Steve. 😃😃😃🇦🇺🇦🇺🇦🇺
You're amazing! Thank you so much for posting this, I've learnt alot! Can I just ask what resistor you was using for the 3 blue leds on the final circuit at the end of the video? I'm using a 9v battery, so I understand it'll be negative resistance, but I wondered why you used one despite this..., I just assumed it was due to any irregular voltage spikes incase it blew the LED...
Thank you Rachel. My next step is to actually make something to see if I understood you correctly. I want to put some LEDs in the bottom of a laser-cut shogi lamp that I plan for Christmas presents. I know with a basic circuit you are wiring direct from LED/resistor to battery so a switch would be necessary. Is a battery-charging circuit a complicated step or should I just have replaceable batteries?
Great video! I'm curious now, what if you had the situation where you had an variable number of potential LEDs attached (let's say someone can come along add an LED at whim) rather than knowing ahead of time. How do you do both A) protect the 1 lonely LED when no others are connected, and B) also providing enough power for when the 10th LED is added?
I just got into 1/14 scale semi trucks and recently bought a bull hauler trailer. I want to light it up like a Christmas tree by adding 50 or so 3mm led side marker/clearance lights. What would be the best method to accomplish this, ideally off a 7.2v lipo battery?
Hello, I’m a novice interested in learning circuits. I have a question about the resistance calculations done at 5:08 : how come we didn’t have to add the current of all for LEDs to figure out the resistance? You divided by .02mAh and not .08mAh (for 4 LEDs). I seems like it’s always .02mAh whether it’s in series or parallel. Thanks in advance!
In series yes, current is always the same for all resistances. Voltage differs for all consecative resistances. In parallel the current value for each resistance will change. But the voltage remains the same.
The video mentions that series circuits are good for when you have a limited power source. Can you elaborate on how many LEDs you could typically connect in series with a 9V battery? Another advantage of series connection is that it requires fewer components. How does this impact the overall cost and size of the circuit? thank u
1.On the last example you have 3 blue LEDs of 3.3 V each so it is more than 9V on that branch with the 9V battery how does it work? 2. If you have a branch or several branches that total 9V (not exceeding 9) which resistor to choose?
I am looking to make a griswold house. I was thinking of using 1.8mm leds, but I could go with 3mm. How would I accomplish this? I want the maximum number of lights on it. It's a Christmas village size ceramic house. I was thinking about using a few terminal distribution blocks that I could hide under the house. Any tips? Any videos you've done that could help?
Maybe a stupid question but there you go 😆 does all this work exactly the same for Smd ? Say I'm using 4 smds in a model car for example? Only thing is smds don't seem to state the ohms. Great video 👍
Finally undestood it all, after over 4 decades of living. School should have had TH-cam 30 years ago!

I learned Series vs. Parallel circuits when I was six years old, but there were no LEDs back then.
Nixie tubes were the big thing.
I'm new to electronics, i wanted to know if i can connect my LED using two different voltage sources without ground
1.On the last example you have 3 blue LEDs of 3.3 V each so it is more than 9V on that branch with the 9V battery how does it work?
2. If you have a branch or several branches that total 9V (not exceeding 9) which resistor to choose?
