finally someone puts together a video that you can actually follow along. most people rush through so fast you can't either follow the audio or what they're clicking on. thank you
Very Good production. This is my first jump into SK6812 RGBW LED strips and Arduino Uno world. "IT's ALIVE !!! " Yep first shot and I couldn't be more happy that it all worked as you outlined. Thank you for this video and thanks to everyone in the Arduino community for all the work you have done to make it possible for the rest of us to enjoy learning this tech.
BRO! I am just 63 seconds into this video and I am your fan! Your style, voice, wisdom, and more is perfect. Your future looks bright!!! Thank you for your time and effort in making us smarter.
Beautifully described each like connection, required materials, circuit, Arduino software, download, library etc....nice teacher.... God bless you all time....help students.... blessings from Indian
One point of correction... "electrons" flow from negative to positive. It would have been better to say "current" instead of "electrons" in your diagram explanation of the flow. Some may argue that "current" also flows from negative to positive as well because "current" is defined as the flow of electrons, but it is generally acceptable to refer to current as flowing from positive to negative.
The way you did the ground--returning from the LED strip, through the Arduino, to the supply--you have potentially 5A of current flowing through a trace on the Arduino board. You ought to make sure that the Arduino trace can handle 5A, or better yet, just connect the grounds.
Most tutorials on RUclips are doing the same thing with 5v pin connected in parallel with the power supply. Why would you ever want your power supply (+) to be connected to the 5v pin? Isn't that dangerous? The flow of current going opposite of what was intended is ok?
Where did you solder the wires from power supply and the capacitor to? I am trying to replicate the way you do it but that part gets me lost!! Also, what do you do with the wires from the LED lights where do you connect them? I know it is said in the video but I just want to make sure!
My Leds flickered and didnt worked as shown. I just powered them with my 5V straigth with the Capacitor and just connected the Data "Pin 6 from the Arduino." Solved it with Supply minus connected to Arduino GND. Seems like Arduino needs that GND thing :D
Hi there, I'm a complete noob here and want to make something like this for a little dirtbike. How would yougo about making it waterproof, chrash proof, and vibration proof?. Im guessing its all the same as the video but with some extras? Plus figuring out the power requirements.
Hi. Can i use 3w led instead of these leds? Will be using 12-18pcs of 3w led constant driver or you advise me which driver is suitable to run 12-18pcs of 3w highpower leds. Im keen to build programmable aquarium leds. Pls advise. Thanks
While I understand what the capacitor does in the circuit, I don’t understand how to determine the size to use.Why use a 1000 µF? Would a 100 µF work just as well? I say this because I have lots smaller capacitors and would have to order a larger one.
great work and u probably wont see my comment but if u do then can you please tell me if i cant program an led strip and place it on my motorcycle in a certain arrangement but my question is do i have to attach the arduino to it or would the led strip be programmed so i just plug n play?
The arduino is the brains of the operation telling which LEDs to light, what colour to be and when to light up. You could always get a smaller arduino nano, and have it run a set routine, or change through a few different routines with a press of a button. It’s more complicated than jusy following this video but it is absolutely possible. Check out Daves Garage for in depth Led programming videos 😁
Hi hope you well I have a bit of a specific question I hope you can maybe help. I'm looking to get the correct "Amber color" on a Ws2811 or ws2812 led strip with the code in CRGB closest I can get is CRGB (170, 75, 0) with brightness of around 80 to 100, this unfortunately is no where close to the amber of let's say an Audi led Indicator. Can you assist with the a CRGB range that might be a closer Amber or is it not possible on this strip?
I dont know if this is a stupid question... buuut! I have a power supply with 5V , 26A.. Is this too much Amps to go into the 5v on my arduino.. I have a 5 meter long NeoPixel strip, with 300 total LEDs on it. Was wondering if i can power both my Arduino and Strip with the same power supply. Right now i power the Arduino with its own "Usb powersupply" 1A. And the strip with the 5V 26 A. Works fine, but would love to just use one power supply. Thanks in advance.
At the start you state the current will flow THROUGH the capacitor. From the perspective of teaching that is incorrect. D.C. current does not flow through a capacitor but simply charge the capacitor. In current mode place a dmm in line with the capacitor, then turn your psu on, a brief (mS) current will flow TO the +ve plate of the capacitor, then stop.
also, I was taught that electrons flow from the negative (ground) to the positive... idk, maybe I'm wrong... but that the "holes" where electrons go, would flow from positive to negative.
Is there any way i can make 100s of addressable switches that turns on and off similar to the led strip? I mean, i want to control a lot of switches individually.
hey i want to ask you if you can save the patterns on the arduino or dosen´t the the light strip reapeat the pattern that you make while the arduino isn´t conectet to the PC?
Most light stips are programmed only with a sertain colour so if the flash though 10 colours using a program they stop at the exact colour when you disconnect the arduino
Do you think I would need a capacitor if this was being used for lighting in a PC? Power would come from the 5v rail from a high end PC psu via a molex and if it did have any sort of voltage spike it would kill the entire computer. Going to be controlled via arduino nano and a windows application on github I found that will control the lighting effects.
I'm too noob on this. Today, the seller said me that I need aproximately 7,5m of led strips, so that 2 power banks weren't going to be enough (by the Amps) :(
Hello. I'm relatively new to the Arduino and leds..I'm looking for a sketch to use to build a marquee sign. Looking for the vintage style light chasing to travel around my home theater sign. Could you direct me?
Same! I’m looking to build signs similar to old-school neon marquees where separate sections light in sequence, like an E-A-T sign at a diner. Haven’t found a suitable sketch or tutorial yet. Will post if I do!
Hmmm I wonder why my LED strips burnt out... Thank you for that circuit! I think that is the reason they broke, also I did not connect them to a PWN pin.... So that could be it too...
Alec this really just depends on how picky you are. At any distance the signal will start experiencing voltage loss because any wire has some amount of resistance. At 100 LEDs I was unable to detect any artifact, which was about 3.3 meters (30 LEDs per Meter). At 200 LEDs, about 6.6 meters, I could definitely tell that the voltage was dropping. I figured this out by turning all the LEDs white. The last 50 LEDs were starting to yellow, which is because blue requires the highest voltage (oksolar.com/led/led_color_chart.htm).
The DC voltage drop across the LEDs is what causes the yellowing in colour correct? ? Although I am referring to the data signal used to drive the led drivers, the PWM signal sent from the arduino, that determines the colours. how many leds can the data pin on the uno drive? or was this also what you were referring to?
Each led driver is a repeater so in theory you should be able to go on forever with data. You need to inject power every 3-5m. My issues is if I put 2m of cable between 2 sections of LEDs then 1 flickers, I need to know how I amplify the data signal.
Old thread but I can’t find how I program a led strip to have one colour but having one led at the time running the length of the strip with the same colour 🤷♂️
finally someone puts together a video that you can actually follow along. most people rush through so fast you can't either follow the audio or what they're clicking on. thank you
I was just thinking the same thing, I am a bit slow at learning so this is just right for me.
still could do something to explain the code. not just copy and paste
True some of em don't gave detail like how many volt capacity to use or not

"The resistor is like the capacitor, it prevents voltage spikes" ... now this is either wrong or *massively* simplified
Voltage drop, is the LED strip expecting somerthing less than a 5V logic signal, maybe even 3.3V
Beautifully described each like connection, required materials, circuit, Arduino software, download, library etc....nice teacher.... God bless you all time....help students.... blessings from Indian
3:33 Great explanation of the capacitor. New Sub for that...
Thanks for all your precious time!!!
5:20 The resistor does NOT prevent voltage spikes. It is current limiting and/or voltage reducing. That depends on how you'd like to visualize V=I*R.
l LOVE IT!! I am definitely making this for on a rc plane. that should be freaking awesome!!!
Very clear descriptions. Great graphic animations.
It works! Thank you so much I am going to put these on my wife's electric bike!
Great Video man very informative! Waiting for the follow up on the coding

The best tutorial on Led and Arduino.. Thanks..👏👌👍
Could I run two 5 meter strands on this setup? Each strand has 150 RGB's.
Yes you could but your biggest issue will be voltage drop. You’ll have to inject power along the strands. 5v isn’t much for that length
Awesome instructional video! Thank you! God bless!
other simple version is get a wifi led driver and connect your led strip and plug it to power, use app to control led from smartphone.
3:43 Actually, there's more of a spike when a transformer based power supply is UNplugged.
is the electrical scheme the same if for example i use 15 meters of strips 18w/m
thank u in advance for the reply:)
good video
nice work dude thanks...
the wires of that power supply are very thin, are you sure they can support 5A?
Using "strandtest" in neopixel library will help anyone uses RGB led strip, anything else is the same
I couldn't seem to find the "next video" that goes into code in a lot more detail as per 13:21
Is it possible to use a 5v phone plug and a usb cable coming out of it
9:20 Do not use a source of ignition. Use an actual heat gun on heat shrink tubing. WAY better results and no burn marks!
Polarity concern? add a Diode - or Two! Wouldn't that tame that beast?
Where did you solder the wires from power supply and the capacitor to? I am trying to replicate the way you do it but that part gets me lost!! Also, what do you do with the wires from the LED lights where do you connect them? I know it is said in the video but I just want to make sure!

Anyone else notice that the electrolytic capacitor in the first image is connected backwards?
How do u control which light effect Is displayed? Does it pick random? I want to be able to control the effect. Thank you
Awesome video, how would i be able to take these and split them up into 4 strips. Where each strip is 25? and the programs run the same on each?
Are you planing on putting the LED's in different areas around the house or do you want to make it one strip? I know this has been a year...

Best Tutorial! :)
When using the usb power of the arduino only where do you connect the capacitor?
hello , i love this project, i want to learn how to configure it in order to react with music, i cant find a tutorial link that uses arduino.
Great Stuff I Hope you keep putting out content. VEry good stuff!
So the arduino can only program neopixel strips and not the regular 3M brand?
3m is just the adhesive on the back. And the arduino can program any LED strip that has the same kind if LEDs as the arduino
Where would you put the resistor if there is only a positive and negative patch on the led strip?
While I understand what the capacitor does in the circuit, I don’t understand how to determine the size to use.Why use a 1000 µF? Would a 100 µF work just as well? I say this because I have lots smaller capacitors and would have to order a larger one.
Why others not using capacitor and resistor?
Are you just carefull or what?

What is the max amount of LED's I can power off with this system?
Hi, what is capacitor voltage ?
In this video you say this only works for RGBW, not RGB.
What do I have to do differently to make it work for RBG as its all I have?
Thanks
Assuming the LEDs are individually addressable, I suggest watching this tutorial: ruclips.net/video/lU1GVVU9gLU/видео.html

No you do not need the capacitor. This is just an extra precaution. You should be fine with your PSU.
Is ohm required too if using a PSU to power the led strips
a $0.05 cap to protect a $10.00 LED strip is a safe choice, the same goes for the 470R resistor.
