- Struggling to decide how to hook up a bunch of LEDs? LED Tutorial #4. Check out this quick, easy & free way to design LED set ups without having to do complicated calculations. In fact, you really don't have to do any math yourself! See how to connect a few or a hundred LEDs to a single power source.
In previous videos I covered:
1. The basics of LED lights (light emitting diodes) and how to use LED lights: • How to use LED lights ...
2. How to use LED lights - Managing Power (adding resistors): • How to use LED lights ...
3. How to Connect Multiple LEDs Together - Tutorial - make a string of lights: • How to Connect Multipl...

Working with LEDs is fun and there are allot of creative projects you can make with LEDs. In future videos I will be sharing many projects that I have made using LEDs to hopefully give you some examples of project ideas that might be right for you. I will also demonstrate how I use a breadboard to test my set ups before I make them permanent. Experiment and have fun.

Wow... that site actually answered a lot of my random questions with all of the bulletpoints below the diagram!
Awesome, so glad it was helpful. Thanks for watching and taking time to leave feedback!
This is the video I was talking about with the great information. As soon as I figure out what kind of leds Im going with and what kind of power source the ship will have, I'll be using those calculators. Thanks again sir!
You are very welcome Greg! If you get a chance to follow-up, I'd love to hear how our project turned out!
no problem! Will do! Thanks for your interest.
Thanks! great info
Hi Chris, thanks for the comment and for checking out my video! I appreciate it.
Excellent thanks.
Thank you very much for the feedback!!
THANKS MAN!
So glad you enjoyed it... thanks for watching and for commenting!
this is great ty very much im in the middle of 3d printing a ferris wheel I want lights on it .great stuff.
Very cool idea! If you get a chance let me know how it turns out, I'd love to hear about it! Thanks for taking the time to comment and for watching.
will do im just going to solder all the electrics and the ill send a pic ty again
How would the circuit diagram change if there was a op sensor connected to each led (op sensor setup to turn each led on when a object passes by it)? Thanks.

Wow!.. just watched your tutorial & found it very interesting.
I am going to try and connect some common cathode RGB led's together for my Christmas tree base ( I lost the power adapter :
Am I right in thinking each of the led legs would need it's own resistor? ( 3 resistors for 3 different colour legs ? )
Thanks again John :)
Thanks for taking the time to watch my video and post a comment / question. I typically use one resistor per LED. [So sorry for the delay... life kinda got in the way for a bit]
Hi, i would like as some questions, i have issues with my current LEDs, and i will use the led for a car model so i hope that will give additional info on how to solve my led problem. Okay here are the questions:
PS: i don't know much on electronics i just knows the basic...
1. Is it possible to wire FIVE 3v LEDs altogether (parallel) and power it using TWO AA batteries?
2. If not possible, how about using TWO 3v CR2032 batteries?
3. The idea is making a headlamp using LEDs for my car model, can you suggest how many LEDs i should use if I'm about to power it using AAs or CR2032? I want to keep it simple due the fact that i have very limited space under the car model.. (if possible I'd prefer avoid using 12v batteries , or bigger in size batteries)
I hope you can answer my questions, and thank you for your help and time answering...
I love the idea! To run your LEDs you will want a power source that has the same or more volts available as required for the LED (in your case that is 3v). 2 AAs will give you 3V but you may not get the total brightness you were after... are you comfortable using resistors with LEDs?
Hi, yes I don't mind using resistor(s) but as long as it doesn't take too much space... I tried using 4 LEDs and wired them parallel to a 2 CR2032 and it lid brightly... I'm not sure though, I'm worry whether it will hold the voltages or not since I don't use any resistor at all... I have the video comin up, I will tag you once I've uploaded the video...
Wonderful video... One correction you might want to make. Starting at 0:44, the word "Example" is misspelled.
Oh that is FUNNY! I can't believe I didn't catch that...doh! Guess that's what I get for editing late at night when I am fried. Thanks for letting me know and for watching my vid!
I tried to delete my comment since you had seen it. I'd rather people just see a compliment. I've really enjoyed your series on LEDs and have learned from it. Great job! I like the format as well. Keep up the good work!
Hi Joseph, thank you very much for the feedback and the sentiment behind it. I am so glad to hear that the content is helpful too!
amen! txs
Very welcome. Thanks for watching and commenting. Hope all is well.
your tutorial simply gave me a final solution, which works! aleluia.
@@walterrldias Awesome! Thanks so much for the feedback.
Cant I use a single resistor connected to all the LEDs? Save me on the soldering please..!!
I totally get it and there are some options. At 15 seconds in I have a diagram of using one resistor on 3 LEDs for a series connection. Another option is to use groups of series connected LEDs and then connect the groups in parallel. I have used on line calculators that allow you to choose from multiple connection options (I don't remember if one of the sites mentioned does this but it is a pretty simple search if necessary) and that can also help to figure out how to set them up with the least amount of soldering. I hope that helps! Thanks for watching and commenting!
Is this site still available - LED Center?
Thank you so much for letting me know... you are right, it has vanished. I added the following comment to the video:

I want to connect to ac
LEDs only work on a dc
Over 5 minutes just to say, use one of the many available online calculators. Great. Why not just go a tiny little step forward and show how simple ohms law really is, so anyone can do the math. Plenty diagrams and explanations on Ohms law available, and you could explain it in simple terms. Ohms law is really not difficult and works without a wifi hotspot or a computer.
