Wii Nunchucks are the best Arduino Input Device

Nunchucks are excellent input devices for your Arduino project! Hopefully I can get you onboard the "nunchucks are great" party bus.

Brilliant! One of these days I should really get around to finishing the project that I built the library for in the first place haha

[@spikekent]

Great video Brian, little lady sure got excited with her robot, very sweet. It's great to see kids interested in tech.

[@BrianLough]

thanks! She was actually playing snake in the shot where you see me pointing at the screen, she definitely seems interested so far so hopefully we can keep it up!

[@spikekent]

@@BrianLough She'll be aa coder in no time 👍

[@grahamnichols1416]

Brian is the hero that makers have dreamt of. Only a son of the emerald isle could realise that "Wat a minute! You're doing it all wrong guys" and put the universe to rights. Thanks a million Brian.

[@GeekDetour]

Oh my goodness! This is a super cool video: loaded with great information - PLUS: your daughter laughing at the Robot is priceless!

[@andrewkieran8942]

A new video from Brian Lough? Woo hoo! My Sunday just got better!

[@BrianLough]

Andrew, you say that like it was over 3 months ago since my last video ... oh wait..

[@andrewkieran8942]

@@BrianLough Given that you recently moved house and have both a newborn, and a toddler, we'll cut you some slack.

[@andymouse]

To put this simply Brian, This tutorial is Awesome !...thank you, and I have dug out my WII and nunchuck you have inspired me...cheers.

[@BrianLough]

That's awesome to hear! Hopefully you can build something fun with it!

[@ChunkySteveo]

Yaaaay! You're back! Great video too, loving the pace and script! And your mini assistant - cuteness overload!! Top work Brian 👌🏻

[@BrianLough]

Thanks Stevo! I think it's your turn to come back next is it? :)

[@ChunkySteveo]

@@BrianLough ssshhhhhhhhhh

[@tetra3dprint]

Nice video and energy there :) Even saw something familiar in there too :D Always a big win getting the little ones engaged in your hobbies!

[@DigicoolThings]

Excellent video! And also a great demonstration of how to test the robustness of your nunchuck’s cable. :-)

[@BrianLough]

Thanks! Man, did I feel dumb recording that!

[@DigicoolThings]

@@BrianLough Don't feel dumb. It's your open, honest, and casual presentation style that makes your videos so enjoyable to watch, and also so popular! :-)

[@simonlbnqx]

You should post the parts with your daughter as separate video to help cheer people up in these pandemic times :-) - it certainly lifted my mood a bit today.

[@BrianLough]

Thanks! I hope you stuck around for the end of the video!

[@MkmeOrg]

Great stuff Brian

[@BrianLough]

Cheers Eric!

[@udance4ever]

wow this is so inspiring! watched this after making an offer on Mercari for a Wii Mote and found your video cuz i wanted to know what the hell ppl do w the Nunchuck and you got me at Tetris :) I’ve been wanted to learn how to tinker like this and this looks like an easy one to start with.

[@DavidGlaude]

Forget about Nunchucks, go for the Classic Joystick or the NES mini Joystick or the SNES mini Joystick. They use the same I2C connector, but offer real buttons and dpad and more.

[@noycebru]

Awesome video!

[@maicod]

you really made this video both informative and funny

[@MaxintRD]

Nice video! That robot surely needs a pair of googly eyes...

[@BrianLough]

You're right! Not sure I actually have any though

[@Afrosy19]

The hunt is on for some nunchuks!

[@miriamramstudio3982]

Excellent video !!!

[@Hasitier]

I should definitely build such a simple robot for my daughter 😀

[@BrianLough]

You should! The d1 mini nunchuck shield I linked to on Github has headers for 3 servo motors so you can just plug everything into that.

[@collie147]

Deadly! And cute!

[@HariWiguna]

Hi Brian! I miss your videos. Always great content! I have to excavate my basement to look for one of those nunchucks.

[@BrianLough]

Thanks Hari, much appreciated! I'm happy to see you back at your bench a little more lately too!

[@TheRealBobHickman]

Woah, I'm famous now. I can sit back and watch the subs/follows roll in :)

[@BrianLough]

Famebucks will be through the roof! This isn't the video I actually asked you about including the clip in, but the video I was referencing at the point is. I had a few seconds of audio that needed a clip and your clocks are awesome so said I'd chuck it in :)

[@MaxintRD]

Subbed and got rolled within 15 secs. Thanks! ;-)

[@paulb36utube]

Really hoping for a twin gimbal (used in RC controllers) game pad. Numb chucks are very cool. Thanks for going over it especially the adapters I’ve seen them on AliExpress and haven’t really had a use for them.

[@DustinWatts]

I would fight you... but I don't wanna do that with a touchscreen! :) All kidding aside, I agree with the cost vs. what you get.

[@BrianLough]

I'd fancy my nunchuck versus a touch screen ok :D

[@rtheawesomegm]

thanks! i'm just wondering, with the double nunchucks, is there a way to make the microcontroller interpret the same button being pressed on different nunchucks as different inputs? i'm new to electronics.

[@derektata]

Ooooooo 😍 This is fantastic!!

[@Moragor]

I bought a nunchuck breakout ages ago, it must be buried somewhere in a box 😅

[@BrianLough]

I know the feeling, something that small could be anywhere!

[@maicod]

2:45 who'd have guessed :)

[@GoatZilla]

Does anyone know how to use the "presence" pin on the nunchuk? It seems barely documented and nobody uses it, but I'd like to use it as a check to see if the controller is plugged in before trying to talk to it.

[@JohnSmith-xq1pz]

I'd love to use one as a mouse

[@James02876]

If you have a cat, you can throw a laser pointer on the gimbal

[@datisreyhani4641]

Hi there, I just wanted to ask what the int value would be if the joystick is moved down the y-axis or the same for the x-axis. It says the values are from 0-255 on the y-axis and the same on the x. Does this mean that the bottom of the y-axis is equal to 0? Or is that -255? Thanks in advance

[@datisreyhani4641]

SOLVED: 128 and above are equal to an up input and below it is a down input.

[@timmyg37]

Could the nunchuck be made to control the cheap rc car wireless?

[@maalonszuman491]

hye i am trying to use my nunchuk for controling my pc like a mouse is it possible?

[@NiHaoMike64]

What about an ESP32 library to connect to a Wiimote? (A quick search finds several, not sure which one is the best.)

[@BrianLough]

From a quick look I didn't see anything straight forward, can you link to what you found?

[@spectrenoir06]

classic controller > nunchuck

[@BrianLough]

I'm just jealous cause I don't have one! I bought a cheap nes looking one from Aliexpress and it didnt work :(

[@dave.madison]

​@@BrianLough Do you remember when you tried it last? The knockoff NES controllers were always a little temperamental, but I updated the library last year so it should now auto-negotiate with them out of the box.

[@BrianLough]

@@dave.madison awesome, will dig it out and test! Thanks for the library!
