Love the video, just another note, you should make sure the cable to your board can transmit data, I can't tell you how much time I have wasted trying to trouble shoot problems with my board only to realize it was a problem with my cable.

Hi , can you please do next video how to connect NeoPxell LED to Pixhawk drone flight controller module, please. Can't wait for that. Thanks

Really useful video, I had no idea it was this simple. I would have loved to see how the colours look but its still pretty cool!

Bonjour combien de pixel maximal peut contrôler un arduino r3 ....merci

so there are all these libraries running in the background. neopixel, fastLed etc? how do I see what effects or functions are available for a particular library? to me it’s like trying to choose a book from a real library, without knowing what kind of books are even available in the library any help would be awesome

Nice video! I'm actually trying to build an arduino project that can control an individually addreseble led strip that has 24 leds using an ir remote. I've got the code and components ready, but I'm worried about the current being an issue. Do you know how much power would approximately be needed, and if so, what gauge/ AWG wire would I need to handle that much current. Also, do you know how to connect a separate power supply to the circuit because I don't think the arduino can handle plugging a power supply into the Power Jack connector.

Im at a roadblock with my neopixel jewel, i dont know if i have the wires connected wrong or if its the board. Im using arduino nano and arduino web editor but these are my questions: 1. I am not sure if my arduino nano came with the adafruit library included, when i put in the code it seems as if the arduino doesnt get that its a neopixel, how would i install the adafruit neopixel into the arduino with web editor? 2. Which ports are supposed to connected on the neopixel? ground, 5v power and input right?

oh my goodness, i am bored right now, i have watched 6 minutes..............i thought it was supposed to be about "Arduino NeoPixel LED Tutorial", not about the hardware side of it. Just a short note about what is needed to do it would have been fine......................... Sorry but, wowsers. And yes, i am straight up.

This is for beginners? 😢 I’m totally lost.

I'm an artist. You're like the first person that has explained this code stuff that I can actually wrap my brain around. Bravo good sir. That's a true gift.

thanks for sharing - very helpful

Hi "So Much Science", thanks for clear explanation about led and arduino, but I've a question on how to construct led in a matrix and how is the code .

Confused to when you say external power. Surely it can only be powered externally as it is not self powered. Also the USB supplies power to all 180 of my LEDs. Why do you say only 8 will power?

I bought an adafruit feather 32u4 and non-adafruit neopixels. will I still be able to programme the leds using the feather?

Thank you so much for this! Super helpful!

Thanks a ton! Very helpful

How should I modify the code for the WRGB Neopixels like the SK6812?

Did you or are you going to make a video with the for loop? I wanted to see or learn how to rotate the colors. Thanks and awesome video!!

Hey, did you show the finally lit up LEDs?

Please make pixel cracker tree with sound circuit

This video is about types of rocket propellants not engines...

Good video. I'm working on an art piece faux-microsatelite - sort of an electronic disco ball that plays StevieWonder 8-bit midi files. Got that same sparkfun red board you showed and I have adafruits neopixel ring. I'm gonna make it sort of retro - sputnik like- maybe a mini telsat. This serves as an educational jumping off point for Ray Kurzweil and his OCR breakthroughs popularized by Stevie Wonder- encouraging more adaptive technology thought exploration and progress. Thank you. SpaceArtShow

the colored sections along the bottom is a really nice touch. wish more creators thought to do that!

Your vid rescued me at Science Lab tonight!❤

WOWWW, amazing video

Really awesome. Just started to learn Processing. I can do lot from here. Thanks for the great video.

Dude! Awesome tutorial and I’ve gotta echo tom, this video should have way more views. Your voice is super soothing too lol

Hello and thank you so much for making this video. I have a question, the neopixel I ordered, has another ground wire extending alongside the data output cable, both of which are connected together to a JST Pin. Can I wire the ground from the JST pin to any of the three grounds on the arduino alongside the separate ground wire? Thank you for your time!

Why do you need an external power supply? I have 256 LEDs hooked up to my arduino and have no issue operating all of them at once. Though, i keep them at max 100,100,100 instead of 255,255,255. Is that the reason why I havent had any issues?

it helped me. Thanks

"We'll cover the External Power Supply, another time" That's what every video says when they get to that point. And that's the part I need to know more about lol.

Hey Bryan: I watched the entire video. It was excellent. You have quite an assortment of concepts that you are transmitting to your potential students/viewers. I have one small suggestion, intended to increase your viewership. Many people are daunted by videos that are this long (>1hour). You can leave this one as it is, but I'd also recommend chopping it up into 10- or 15-minute chunks and make a playlist out of it. You already have very clearly marked sections (File management, basic Perling, Sun, Colors, recursion, etc.) so this should lend itself to chopping nicely. Do try that as I feel your video really needs a whole lot more views. Regards!

If "in depth" was a video :)

Just starting out with arduino and LED's. Had a lot on this video. Thanks for that!

Hi Hermann from Germany here. I’m trying to code a sun and moon light animation for my African hedgehog terrarium with these led’s. Some how I can’t figure out how I can switch the four variables to the value I want, send to the Arduino Bord by my pc. I am searching and searching, but I can’t find a tutorial for changing these four variables. For example if I insert a Variable in the led number Variable, Arduino says ‘variable’ was not declared in this scope.

how can you do to connect 3 neopixel in 4 corner traffic light system, i tried and i can only with 1

Over a year later and I just learned a lot from this video. I very much appreciate you taking the time to create it. I received an Arduino for an early Christmas present and after looking at what they can do I realized it was the perfect solution for a project I had been thinking about for a long time. This video checked off two items on a somewhat long list of things I need to learn. Thanks again!

Hello, thanks for this informative and basic LED Neopixel tutorial. I have a question for you, maybe you can point me to the info I need? I am not programmer but I do have some skills in building electronics and soldering. I am also into midi music and have been looking for a simple method to take midi data input via 5 pin midi, and assign it to a strip of LEDs so that I can put the LED strip on the top of a keyboard and play midi files from sequencer software that will show someone how to play the music. The Arduino should be capable of doing this. I have run across several systems on KZbin using Raspberry pi, but it seems I have not found a simple midi input to LED out type solution. If you know of any scripts written to do this I would appreciate the info. Thanks

This works with WS2811 led strip?

Thank you for going through it. I have neo pixels with an additional color white. Haven't received those yet but will need to program that fourth white color. Also I will need to assign the intensity for each color to an outside control like a knob.

is it always necessary to use the adafruit library? I tried using basic digitalWrite and it does not light up my strip.

Hi there, if started a new project and desided to make a custom code, a few hours back I watched your tutarial and it was really helpfull. but if got a question cose i got a problem, see, im making a big sign that says Moxxi's. consist out of 254 leds inside a defuse tube. if connected it on one strip and want the letters M, o, x, x, and s. to be constand 1 colour and i want to animate the heart (the dot on the i is a heart) to be animeted. my question is (cose my code is getting really big). is there a way to say led 1/57 be red cose thats all the leds in the letter M. for example: pixels.setPixelColor(0-57, pixels.Color(255,255,0)); instread of every pixel given his own line.. i couldnt find any codes on the internet or any other tutorial as helpfull as yours. hope you could help me out. thanks!

hello sir i need your help

If I had 405 LEDs, then I would go from 0 to 403 cuz 404 doesnt exist

Thnks for explain me about this!, ASAP I'll get the material for this project, can't wait to ur next video!, note: please next video show the final project working! :), sorry the project working was at the begining of the video.

were is the code below

This was a great video and thank you for posting it, but I will say that I have a 144 WS2811B LEDs running without problems, no extra Power supply, only the 5 VDC out Pin, this is on a genuine Arduino Uno powered by my computer and nothing else. Please feel free to reach out to me for any questions.

Absolutely AMAZING video! Best beginner tutorial I've found.

This dude taught me more about coding and what things mean than anybody, thanks alot.

I'm trying to do this with a Arduino Mega (clone). It ain't workinn. :[ If there's something about megas or clones I should be doing differently let me know
