I love the “buy my books” outfit
I read buy my boobs XD
@Leo cosplay
She is doing something productive and she enjoys what she does.
@shadowflare99
That is a derogatory comments, have some respect for a lady, if you cannot say something good about someone, then say nothing at all.
Mashallah, she is beautiful.
@@rizwanrafeek3811 Cringe White knight.
Rizwan Rafeek actually, it’s more derogatory to put her on a pedestal when she is a human like the rest of us. the comment you replied to wasn’t offensive, they misread the comment. white knighting someone makes you look desperate, so just stop.
@@user-sj9gz7pr3l _"actually, it’s more derogatory to put her on a pedestal "_
Jealousy and envy wouldn't take you in any direction in life.
_"when she is a human like the rest of us. "_
I don't disagree.
_"the comment you replied to wasn’t offensive, "_
That is so in your World.
_"white knighting someone makes you look desperate, so just stop.
"_
I don't know her personally, but she is doing something and presenting something to rest of the World and she enjoys it, that is all matters. If she makes money out of it, two thumps up for her.
Note that the LED strip used is WS2812B. They're individually addressable LEDs that have the WS2812B chip inside each one. The signal goes into *signal in* and goes out of "signal out" into the next strip's "signal in". Note that the Arduino is incapable of driving a long strip. For that you'll need to add 5V power to the strip. The reason why you have to specify the length of the strip and how the chips determine how many LEDs are in the strip is because after the signal passes through one LED, a bit of data gets added that tells the next chip how many times the data has previously passed through a chip. The Arduino needs to know how many LEDs there are so that half of the strip isn't dark if not enough LEDs are specified. If the number of LEDs falls short, the next LED won't know what color it should be, what brightness etc. It defaults to all colors off because the data isn't *addressed* to it or the following LEDs.
If you want extra modes in your code, you can use *variables.* You can change the state of a variable based on an event, and then call a variable and execute the function it matches. Let's say you make a variable called Mode. You can add a number to the variable. Let's say each time you press a button, the variable number grows by 1. The variable will be set to 0 at the start of the sketch. When you press the button the variable reaches 1 and an animation code is executed. If the variable reaches 2, a different animation is executed. You can now press the button again to set the variable to 3. Now another animation will be played. But when the variable gets to 4, a different code is executed. Now it sets the variable to 0. When the variable is 0, no animation is played and all LEDs are off. Don't forget to add the part that resets the variable to 0 or it will continue to grow until you either reset or the variable can't fit into the memory of the Arduino anymore. You can have the variable start from 1 and get reset to 1 if you want the animations to cycle instead of turning off. You can add as many variables as the memory of the Arduino permits to perform a lot of modes.
Wow i don't understand
Thank you, Bro, I got the concepts. :)
Maestro, maestrazo!
Thank u
Shut up nerd
Also a small note, if you want to 'disable' multiple lines in your code you can type /* 'whatever code you don't need' */
For example:
/* rainbow(20);
rainbowCycle(20); */
This will disable everything between the two 'markers' in your code. It's just a neat shortcut if you have to disable lots of lines which are right after each other :)
lol, that comment is to nerdy... no thumbs up because its actual real IT nerd stuff! xD
also, you could delete the code, but what does i know.
@@TheValinov how is that too nerdy?^^ it's just arduino code :)
commenting out parts is really usefull to find out which part of the code is not working without having to redo it all :D
(Serial monitor also helps a lot when debugging :)
@@TheValinov lol, that's fair xD
One reason to use '//' and '/**/' instead of deleting the code, might be because you're testing specific lines and might need just some parts of your overall code, then you won't have to rewrite or write the code elsewhere while you're testing! Another thing you can use it for is to comment your own code e.g //if you need to change the color of x change the numbers in this line.
Commenting is especially helpful if you haven't touched your code for months, then it's nice getting a quick overview of what the hell is happening in your sketch :)
You could also use ctrl + / which comments it. It's a useful shortcut I think it works for arduino ide.
Could also use ctrl + / and it will comment everything, same for uncommenting.
And to tabutale use tab, BUT if you want to untab0 just use maj + tab
btw if you're getting an error with the "old" strandtest code from the link in the descrpition make sure to add after #include at the top :)
Helped a big bunch. Appreciated amigo
I love how much energy you manage to pack into your videos! 🤩
Adorable and informative, I enjoy playing around with code, but never thought to put it into my clothing. I need to start a new project now. Thank you for your videos. :-)
I think your top worked on me. I just went and bought the complete digital set of books. After a quick scan through I can say I'm already happy with my purchase!! Love your work!
This definitely takes some practice but is an awesome elevation to any cosplay. Also, I don't know which of you does the editing of your videos but it cracks me up...I love it. You two are so creative and cleaver with your videos. BHB.
Thank God my husband went into programming and knows all about writing codes. He showed me that me made a simple calculator for a project once, so I have faith he can help me with this when I get things wrong.
I am studying electronic engineer, I am otaku and I like to do cosplay, this video shows me my true destiny
What cosplay do you do?
This came up exactly when I was looking for a tutorial on the code! Thank you!
Anyway! Now everybody know that we are all going to continue to have a hard time until Kamui explain how to do stuff!!!!
So today I propose officialy to create the ultimate source of knowlege: Kamuipedia
PS:
This is an awesome tutorial. I've always been scared to look into arduino, but you made it simple. As soon as I get some funds I will try it. Thank you so much, and thanks for sharing.
lol.. I must say that is a cute dress! It's been fun over the past couple years that I've been watching your videos waiting for you to somehow promote your books.. but this is by far the best! You are awesome and I love your work.
I needed this video to make the cosplay of my dreams exactly as I imagined, and now that I can and that I know that its not as hard ad i thought, i can finally cry tears of joy 😭
Thank you Svetlana, you and Benni will always be my favourite crafters and cosplayer ever!
!!!!!! aaaa I wanna make light up stuff now!!! This is so exciting!!! thank you so much for making awesome tutorials!!! Also the corgi animation are adorable!!!
this is very similar to working with prim code in 'second life' some years back
and this is very handy for where to find the board + run program
Wow ive been working with microcontrollers for uear but your project is the first time ive seen anything this creative. Great video.
Neopixel LEDs are also used in the lightsaber community to get realistic Blade effects :)
This girl and this channel are awesome! She explains so well and always has a big smile ok her face. She has a really good vibe!
Thanks for all the tips and videos!
Your videos are so informative and fun!!!
Thank you for making them!!!
Super helpful! Looks like there are some things in the book I can revisit, too.
Love the dress. I think you are definitely sending a message about your books. 😀
I love the corgi animations!
Programming 101: Google the code, don't write it yourself. Seriously.
Haha I know right?
First thing my animation professor ever said us, "If you can find a way to cheat, do it!". Best advise I ever got.
Well you do learn more if you write it yourself... besides this code wasn’t that complicated if you have a basic idea of Arduino/ C++ Code
@MisclickMilk uni teaches u the basic. U can't copy paste anything. Also it's still important to know the basics. I really don't think u will pass any coding interviews otherwise.
Great advice lol 😂
Woah! Thank you so much for this! I was racking my brain figuring out if i wanted to dip my toes back to coding or just build separate machines to light ip my gun project. This simplifies it so much.! Fan of your cosplay on fb. You are so magnificent! So far i build for fun but I’ll eventually move towards selling.
That's a really great explanation! Thank you so much! That helps me a lot :)
Hi Svetlana this has been a massive help and so simple. many thanks
Code is absolutely terrifying to me but you made this so easy! Thank you so much!
Her genuine unbridled excitement is adorable.
should have known your channel would have the best answer for my question. thanks
!!
Inspired? Love you just "killed" me ;) Im rebuilding the interior on my old Audi TT and you just showed me a total new way to do so! Thank you and keep up the good work, it´s amasing to see your costumes they look fantastic!
Holy snap! I really hope I can find someone who knows what they are doing when I get this far in my cosplay. I quit programming over forty years ago. I used to know BASIC and APL pretty well, but... Can imagine I'll be watching this one over and over again... Wow.
if you know one language you know them all :D between most languages transfer is really easy because you know how stuff works and only need to figure out how to express it properly :)
I know very little about LEDs and I’m planning to do some Bioshock Big Sister/ Big Daddy cosplays and wanted to make the light in the helmets change between red and white so this is absolutely perfect, thank you Kamui!! I’m definitely gonna look into your LED book, I feel like I’m getting the hang of this : )
if you want to use white light you should look into rgbw-leds, they have a separate led for white, which uses less power than red,green,blue together (which is the rgb-way of making white)... so your battery will last longer :)
(not sure if the library covers those but i think it might)
@@johnuferbach9166 Thank you! I'll look into that
Love the corgi animations!
AMAZING! Thanks a lot for the tutorial!
I love you and you are the best!!!! Why can’t I meet someone with your energy and knowledge! So cool and nice videos
Another interesting and well-presented video. You have a great technique
Love your vest😂
Also thank you for the vid
Thank you so much this extremely helpful. This answers some problems i had.
Glad to hear it
Тот случай когда ищешь идеи на английском, а тут Светлана рассказывает забавную идею достаточно подробно. Спасибо, пойду дальше кодить свои поделки.
Oh, thank you! I have arduino now in my studies :D
I really do love watching your video you are very informative and bring up subjects I would not have thought about thank you you're helping make my cosplay so much easier seriously thank you I've even been using your information for items and remakes of items in my man cave I have used your ideas thank you for Fallout helmets Bluetooth motion speakers and countless others thank you
Always glad to help out! :)
Great instructional video! Thank you for posting this! God bless.
Make more books and I'll buy them! I have almost all of them hahaha
OMG! I already Loved you when I saw all your costume stuff, Now you are my FAVORITE person!!! I messing with LEDs right now and ran into this looking for button examples.
haha I'm always there to help!
Really helpful tutorial!!!! Thanks a lot from Belgium. And BTW, really cool dress :p
Great work as always !!
Ok, thats the book that i need
I love your enthusiasm! Thanks for the video, I found it useful. I'm now less afraid to dabble in coding now.
hallo, Retro Stuff guy,
if you want to give a try, go to wokwi.com you can edit code as well as see the outputs. Paly with motors, LEDs, or high-end displays.. it is very easy and not at all confusing.. Give a try today 😊
I wanna make a zinogre suit in the future that has the exact build of the monster for the body and lights up exactly like the real thing does. It will take some time until I have the practice (started using a dremel for my second project now so still a bit rough with skills) but that is a big dream of mine. I hope and will work hard for it
My brother just graduated as a computer engineer (programmer) and my dad worked for ten years running an electrical power plant (making circuits for light dimmers) so I’m just gonna recruit them :D
You are awesome and I am totally buying your books!
So this was my first time watching a Kamuicosplay video and my initial thought was "Gee she needs to cut back on the caffeine in-take", and I was going to close the window but I'm so glad I stuck through and watched the whole video. Super informative and the cosplay costumes are simply amazing.
Thank you! That makes it much less confusing.
I am new to your channel and i love it so far. Can you do a video showing your setup, like the sewing machine you use or 3d printer etc.
Me encantan tus videos y tus cosplays, me ayudas a ver que aun tengo mucho que aprender
Simply amazing!!!
Nach genau so einem Video hab ich gesucht !!!
Freut mich zu helfen!
Thank you sooo much! trust me I'll put led's everywhere!
Amazing Kamui!
Best tutorial video , subscribed
I love that you’re doing Arduino
Parabéns pelo trabalho eu adoro assistir seus vídeos 😍 sou do Rio de janeiro (Brasil)
Amazingly explained!!
Just what I needed thanks heaps!!
I just love your positive vib you have wen you teaching us lol
you can also use a pushbutton and have it change a variable when pushed, which will also work to switch modes (you should supress (with if) further pressing for like 200ms afterwards though, because buttons usually aren't as binary as one would think (usually the voltage will be unstable for a bit when pressing which can trigger more button presses at once)
Yes I know, but I preferred the slide switch since it keeps the example easier and some copy&paste is already enough to make the code work. :)
@@KamuiCosplay yeah, i figured... but i couldn't help telling you anyway :x ^^
LOL.. Nice dress.. Thumbs Up just for the dress
Amazing as always!!!
This is what I needed! Thanks!
Glad to help!
Thank you for another amazing video
It's also helpful to note here, most especially for beginners, that this guide applies to 5-volt (3 wire) type neopixel led strips. If you are using an analog 4 wire 12-volt led strip the code given here will not work. The example sketches will run but the LEDs will be extremely faint and almost impossible to see.
Wow that was alot and feel like raging but I always get like that when am trying something that looks hard.This is very informative and I will use this leds in agni and rudra.I usually get thought it.
I am not into Cosplay at all, but i have an (my first acutally) upcoming DIY project where i want to code some LED stripes to fade between two specific colors and it was described perfectly in this tutorial so thank you Svetlana!
if space is a concern don't forget to use an arduino nano, it's basicpy the same but a lot smaller :)
@@johnuferbach9166 I did not even consider space until now! It's supposed to fit behind a kind of deep picture frame. And i ordered an off-brand Arduino Uno R3 from geekcreit i believe. It'll be my first time playing with electronics but i'll figure something out once all arrives next week or so
@@Feralas100 ok, i guess in a picture frame there is plenty of space :D also a cheap nano is like 2$ and one can never have too many arduinos, so even changing your mind wont hurt much :D
how are you planning to power it btw? :)
@@johnuferbach9166 i bought a ac 100-240V to dc 12V 5A 60W power supply adapter for led stripes and i hope to just be kinda able to plug it in the wall and see what, that may be a rookie move though haha
@@Feralas100 dayum, thats pretty beefy, how many leds are you planning to run (and in what color ect^^) and do they work with 12v? the arduinos voltage converter can only handle so much current (apparently the 5V converter can handle up to 900mA (from 12V more like 700 or so it seems) though might be further limited thermally
beautiful and smart
Just bought this book!
I am sure my husband would enjoy this and he would say "pff... too easy". He works with huge machines and he can program and fix them hahahah.
I however, has been playing with website codes since younger but I didn't enjoy doing it lately.
Still, kinda of easy to understand.
Thank you very much!
Just want to say you are so talented
Just have to say that the top she is wearing is the best! :)
What is the diffusing sponge used? The effects are really cool when you spread out the light. Mine are way to centralized where the LED is. Thanks fam!
Fantabulous!! Thank you!!!
I'm going to buy your book. So excited.
Yay! Thank you!
Definitely gonna ask my boyfriend to translate this talk for me lolol, I understood what it meant but it flew out of my mind as fast as it came in
just an amazing work
Impressive! Now, to buy the strips!
oh gosh, just what I wanted to watch 😁😁
Great tutorial. Love using arduinos. Best way is to mess and have fun as you say! Good guide 😊😊
Did you just say [Thunderfury, blessed blade of the Windseeker] ? :o
Thank you so much
keep it going
Hey thanks soo much for making this! I really want to make a special keyblade!
Do it! That's a great idea.
William Crawford yea its the one with stain glass.
I love your videos soooo much! And you helped me with this tutorial I really appreciate!❤❤
Glad if I can help! :)
You uploaded this a few years ago, so you may or may not know about this already, but when you use the switch you can pretty easily add code to the rainbow loops that would interrupt the loops and bail out of the functions. One of the cleanest ways would be to just pass in information about the state of the switch when you enter the function, then at the top of every loop just check if the state of the switch has changed, if so, end the loop.
Something is telling me to buy your books but i don't know what it is....
what material are you putting on top of the leds so it diffuses like that - at 5min in for example? Is it just normal eva foam?
I love your personality so bubbly ☺️
Excellent!
So in love with this woman!😁😍
what power supply do you use for your LED microcontroller solution? a 9v battery block? li-ion batteries? and how much voltage is applied to the microcontroller? so then at the end built into the cosplay?
Thanks cool video!
You are just ..like the most adorable ever :) I just found you, but I really love your style. Thanks for the tips Svetlana :)
Does the Arduino need to stay connected to the LED strip in order for the programming to work, or does the strip have memory built in?
