Yup, the MEGA 1280 can work with the Wii nunchuck (or with any other I2C device, like a BlinkM). The MEGA however has the I2C pins (SDA & SCL) as their own pins instead of being shared with Analog 4 & 5 like on a regular Arduino.

So instead, you’ll have to do a small amount of wiring. See this diagram for hooking up BlinkMs to a MEGA, it’s the same:

Dang it! ive got a MEGA 1280….any suggestions?…. does the mega not have the required functionality?.. I realy want to get it working… what should i look for or change…
sorry to spam ur blog…..
Your help is invaluable….

thanks for your time!

Hi,
What kind of Arduino do you have?
If you have a MEGA or something else other than the regular Arduino board, plugging in the adapter into pins 2,3,4,5 will likely not work.

Hey there Todbot,
I am in awe of this work..
I spent a few hours with my arduino plgged in pins 2345 as said above but for some reason when i take a multimeter across pins 2 and 3 i dont get any voltage.. Has any one had such an issue??? any ideas whats goin on… Crossing my fingers that my arduino’s not busted!! :(
the code loads successfuly but no voltage..

any help is much appreciated…
Cheers

Hello TodBot,

Hey thanks, had a great time playing with your information/code. May use it with my astronomy project, needed a human interface and this may be the answer.

Thanks,
Chip

Hello TodBot,

I am a high school student taking an Introduction to Engineering class. For my final project, I am collaborating with another to make a Tactile Tic Tac Toe game for the blind, and I decided that a Wii Nunchuck was the best controller to use. I am very thankful to have found the library you made. I didn’t have to get an adapter because I found that it works if you insert wires into the little holes on the side. I was wondering if I should do anything else, or anything you would like me to do, besides putting the link to this page.

If you are interested, you can find more information on our project blogs:

Hi Ali,
There is the possibility of using any two digital pins with a “Software I2C” library that does all the I2C functionality in code rather than using the built-in hardware of the AVR chip on the Arduino. I don’t know off the top of my head an Arduino Software I2C library that works with the Wii Nunchuck. I haven’t look very carefully though, maybe you will have better luck searching. If you find something, please let me know.

Hi Todbot,

I’m currently developing a vocal manipulator patch in Max Msp. I inherited a BT-V06 already programmed for a uni project. This is currently using all analog pins to an outboard breadboard connected to piezo and flex sensors. I could sacrifice freeing up 1 of these only if needed.
However, the digital connections are unused. I was hoping to use your adapter for more functionality of parameters but notice prior to ordering that you suggest using the analog inputs. Is it possible to use the digital ones as well or would this just not work please? I’m not very good with electronics so any help is much appreciated. If you could offer any suggestions please without having to recode the board, that would be great. As this isnt an option.

Thanks in advance,
kind regards

Ali

Your adapter is very useful! Thank you, it helped me a lot!

I wrote a new Wii Nunchuk library for Arduino. I used another initialization method, so that the data bytes are unencrypted and some 3rd party controllers work. I also included the data from bits 2-7 from byte 5 in order to increase the precision of the accelerometer. You can read more about it below:

Hi, i’m new in this arduino stuff and i am experimenting some issues on my own, first i’m not getting any god response from the arduino you see when i start running the COM board i only see zeros, then when i press the reset button and i move the joystick the values from the axes turned into 255, and the “zbut” and “cbut” still zero, i already saw the connnection of the arduino and the nunchuk and it’s ok any sugesstions?

Hi Richard,

Did you download the WiichuckDemo.zip zip file, uncompress it, and open the .pde file in there? That zip is all setup to work well on Arduino 0023 and earlier. (It doesn’t quite work yet for Arduino 1.0)

Do not put the “nunchuck_funcs.h” file in a “libraries” directory. It won’t work. It should be in the same directory as the WiichuckDemo.pde file.

“Hi
I’m new to Arduino and an having trouble with teh WiiChuckDemo.
Whenever I run verify the demo I get loads of errors, with the top one being
‘WiichuckDemo.cpp:9:28: error: nunchuck_funcs.h: No such file or directory’
Looking at the Arduino help, I’ve created a libraries folder under my project folder (with the nunchuck_funcs.h inside), but still get same errors. I’ve also stuck libraries folder in a number of places, but no success.

Any suggestions?
Thanks”

Same problem as Martin.
How did you fix it Martin?
