Finally undestood it all, after over 4 decades of living. School should have had RUclips 30 years ago!
Enjoyable to watch. Love her plain talk around calculating resistance. ❤
One of the best explained videos on parallel and series connections. Well done that girl. Puts all the blokes to shame.... 👍👍
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.
Good clear bright presentation !
Thanks
I agree with most folks I am sure that this is one of if not the best Vid helping me to understand Parallel and series LED connections. Subscribed!
this is exactly what i was hoping to find. the significance of this information is so valuable. and you are the loveliest person. thank you
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.
Thank you. Your videos are nice to watch. You explain it very well and clearly.
Nice explanation by a very nice lady. Good to see a lady explaining electronics.
Fabulous explanation. I can go forward with lighting my model railway layout. Thank you Rachel.
❤ this thank you. I'M NEARLY 60 and want to get my grand kids doing something different. So I'm having to learn this first. Great tutorial
I've just started getting into electronics and finding your videos so helpful. Thank you 😊

Great beginner friendly explanation.
The coin battery is a great tip. Never thought of that. Beats always pulling out the alligator clips or breadboard every time I need to check one.
Having first learned to use LEDs on a breadboard with Arduino. I used to do the same thing!
can we use Arduino to make automatic sachet packaging machine that can weight and pack?@@RachelDeBarrosLive
Thank you, I had a eureka moment when you so easily explained parallel curcuit for LED. Woohoo!
Great videos!! I love your delivery, keeping it interesting and not intimidating!
Thank you for you informative and enthusiastic knowledge share on LEDs. Helped with a project I'm embarking on.
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 !!!!
your methodology is great 👍
Thank you so much for this tutorial, so many others I've come across have been a bit convoluted, but you make it clear and easy to understand.
ruclips.net/channel/UCLmreVv7Nm2G6zwO9JUjpeg
Totally agree. This video covered all of my questions. So thorough. I really appreciate it.
Exceptional pedagogy.
Good stuff! You’re an awesome instructor/teacher. My favorite YT girl! ❤
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!
Love the bangs. Come to LA and help me with my projects.
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
Yvonne de Carlo, she was so amazing! Great taste and thanks for all the great information in your videos. Thanks for your time!
Thanks for watching! Let me know if there's any other topics you'd like me to cover!
Really helpful. I'm about to wire up 800+ LEDs for a Ace Frehley flashing guitar. Fingers crossed
I'm a little disappointed you didn't let the smoke out of any of them. Electro-boom has me jaded. Your excitement is quite infectious though. Is there a blooper reel?
Awesome explanations!
Thanks!
Great video! Love the T-shirt!
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.
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.
awesome, so smart
🎉🎉 My metal spider project will have several of your freakish LED circuits used! See ya on the next live workshop!! 🎉🎉
Yaaas!!!! 🤣
Wonderful explanation to extrapolate to christmas tree lights
Glad you found it helpful. Once I understood the different arrangements I got much better at fixing broken light strings.
Cool video Rachel I get tons of those kits😁👍🤖
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!
Glad you found it helpful! Let me know if there's any topic you'd like to see in the future.
Fun fact: power (electrons) flow from negative to possitive.
They found this out in the mid 20th century but since all the notation of all circuits was written, we left it that way. But if you want to be accurate, power flows from negative to possitive. That's why i like to place the resistors from the negative end :).
Me too! I've been placing resistors on the negative end for years. For whatever reason, when I started working with Arduino I switched to the anode. I'm not sure why but maybe it's because most of the wiring diagrams had it that way so I eventually caved to peer pressure and switched 😄
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.
Love the Tee Shirt!
I have systems but all are powered by solar panels. ❤️ electronics. BTW, I use breadboards & LIght Dependent Resistors. ‘Basically’ they’re off during the day, at night they keep my room lit.
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?
COOL,,,,,,IM SUBSCIBED...GOOD WORK,,,,ME LADY!!!!!!!!!!💯👍👍👍
Another way to tell which way around LEDs go is the "cathode is the cup". Look through the side of the LED and one of the connections goes to a more cup shape. That is the negative, or cathode connection.
Different colors can be wired in series. Just add up the voltages of the LEDs, subtract that number from the source voltage and calculate the resistor.
first one here great content.
Positive isn't always the long leg. Some are backwards. Check yours before you install them.
The LED can generally take about 5V reverse. A 3V cell is fine for a polarity check. A 12V supply and a resistor is dangerous to use for polarity checking. Most will be fine but some will get cooked.
The colorless case ones can be very handy because there is no color until you apply the power. This makes more contrast in a blinking design.
Also remember less current makes less light. You can run your LEDs at a lower current if they will be too bright at night. In a dark room, you can see an LED running on 0.1mA (0.0001A)

Do u have a video on how to hook up filaments??
Hi, so i ordered like 2 packs of 50pc. 3mm red defused leds i am trying to connect 6 of them together but they all wanna flash at separate rates, what do i need to do in order to make them all flash at the same time ? Im doing a 3 on row front and back. 6 total.
Have you seen those fairy light strings that have only two wires, but can alternate every other LED, turning half on and half off or all on, and can fade each set (odds and even) on and off but opposite each other? I wondered HOW this was possible, and can only imagine that the controller is switching polarity so fast we can't see it, but can feed both sets simultaneously. Wild...
I need some help. I'm working on a project. What I want to do is place 5 leds on a light switch cover, and a few push buttons, one to each light. I want to pull power for them directly from the side of the light switch if possible (safely) so that I can push the buttons and light the leds (with the light switch on or off if possible, if not then when on is ok.) I just have no idea about how to draw this small amount of power from it. The leds are blink type and small. Any suggestions? I want to use the stock light cover if possible. Thanks!
I'm trying to hook up three 5mm white leds and two red 3mm leds, as well as, two yellow 3mm leds to a small motion sensor. When the motion sensor is activated, the leds will turn on. It is to be used in a model car, so when people passes the car the lights will turn on. Can you show me in a video on how to do that. That would be great. This without using a breadboard because it needs to fit in the car, van or truck model kit. Hope to hear back soon because there is no video on how to do something like this.
I'm working on a flux capacitor, and if successful I will see you yesterday.
Hi Rachel, I stumbled across your channel while trying to find out on how to convert power hungry antique outdoor incandescent Christmas decorations that have been in my family for close to 50 years. One decoration an X candy cane stands about 40” tall about 24” wide and has about 180 lights, Red, Blue Green and some clear. Many of the bulbs are burnt out and they cost about $1.75 Canadian each to replace. I’m not sure on how to calculate to run it in a parallel circuit nor the type of wire to use as well how big of a transformer I would need? Any advice or guidance would be greatly appreciated, BTW not sure if it matters but our winters can get down to - 45C to -50C does that have an effect on the type of wire? I have watched a few of your videos, you have a new subscriber 🙂 Take care, Wayne
For some reason i get the feeling its not just the LEDS that are wired 😂😂😂😂 🥰🥰🥰
Omg. You are my people! I'm a nurse, but I think I was meant to be in electronics! I'm trying to figure out how to put an LED on my 48v 100ah batteries so that I can see if the pack is on.
That's a great idea! Let me know how you make out.
Here you also have to consider how much power will be dissipated in the resistor. For 1 LED at, say 3V, there will be 45V across the resistor. Power in a single part is the voltage across that part times the current thru it. So 45V x 0.02A is 0.9W. A 1W resistor would technically be enough but good practice is to stay under half of the power rating, so a 2W or greater resistor. Also almost 1 watt is significant heat.
what is the thinnest 2 core cable i can use for LEDS Please ?
Hi Rachel. You do some really cool vids here.
I'd like to see, in each vid, Safety Tips & Hints.
Your "Wall Wart" has enough Power to kill... Given the right situation...
8 hobbyists and 3 professionals die every day, its no joke.
Hi, at 11 min in video, If I was to use one resistor instead which I think you can do (correct me if I an wrong) then you would be 80ohms?
How about a video on how to set cameras and screens like you have😊
Can I use a 9v battery with 4 white 5mm led diode?
So if I supply 3v to a parallel circuit of four 3mm LEDs that have a VF of 3 - 3.2 v..... do I not need to use a resistor? I have some 0 ohm resistors, is this what they are for?
can we use Arduino to make automatic sachet packaging machine that can weight and pack?
Is the resistor always needed? Cause I’m making some light trees made out of polymer clay. And have already made 1 that works and didn’t know about resistor.
3:40 Any EE will tell you that the power 'flows' from negative to positive - not pos to neg
did you use copper wire?
can non copper wire from battery holder connected with copper wires?
Good mem,I am indian
These leds seems to be resource hogs. Am I right in thinking that based on your example in the beginning of the video that even if you used a 120v wall outlet to power the series, you still would only be able to do 60ish lights?
5:13 AMA BEGGINER, GOT A QUESTION, WHAT RESISTOR I USE IF I LIGHT UP 20 LED RED LIGHT IN A ROW WITH ONE SWITCH BUTTON DO I REALLY NEED A RESISTOR?, AND ABOUT THE BATTERY, IS IT ENOUGH TO USE 9V TO POWER UP? I MEAN IF USING 3MM LED LIGHT :)
omg i finally found a vid without mansplaining! i can actually understand lmao
Inside is a little flag for the negative never trust the legs
17:33 WHAT IF 10 LED LIGHTS PER SIDE? IT STILL SAFE? :)
I’m working on an Iron Man model that I am going to light. Let’s see what happens.
If you mildly overvoltage them they smoke.
If you put 12 volts on them they can explode,.. nobody warns of that.
Be careful, might even want eye protection when running these from 12 volts and a potentiometer.
Colored LEDs and color emitting LEDs aren't the same, the colored ones are just white LEDs with tint
OMG! I am 56 and have a crush on this woman lol
She is 🔥 isn't she ? I enjoy watching her she makes projects easy love her.
I’m so lost
You can find the flat spot by feeling with a fingernail, oops ;)
Beautiful hair. 🙂
I smell something burning in the kitchen. Maybe you should go there check
Miss ... That is a MALE CONNECTOR
