It is now works perfectly.And I like your library… thank you..

If you are using an Arduino Uno, you have connected it correctly. However, you may have made a mistake while connecting to the Wii Nunchuk’s connector. Are you using an adapter? Make sure that you have wired it correctly. Look at the following figure. It may help you:

The connections to your Arduino seems correct.

If you still don’t manage to fix it, please let me know and we’ll look more in this. Good luck!

I have a problem like several person below.. It keeps send this value to serial 20486 -32248 1024 1026 -21466 1 1

I am using Original Nintendo Wii Nunchuk.

I newest Arduino… (just bought it October 2011).

I connect ‘+’ to 3.3V,

‘-’ to GND,

‘c’ to A5,

‘d’ to A4.

Would you mind if you help me?

Theoretically, the values for the accelerometer would be in the 0-1024 range. However, the values have a smaller range, like Adrian said. I believe that these values change from controller to controller, so I think that the best solution would be to test them using your own controller. Regarding the buttons, 0 and 1 are the only possible values.

I also plan to work with servos and an Arduino Nunchuk. I’ve ordered some servos, but they haven’t arrived yet, so I can’t really help you with this right now. When I get them, I’ll test some scripts and I’ll let you know what works best for me.

When you complete your project, post it here. I’d like to see it! Thank you for visiting!

I am new to Arduino but feel I’m picking it up very quickly, but know I have lots to learn in the code writing department. I am working on a project and would like to integrate a wii nunchuck. I intend to make my own nunchuck adapter, but for now I don’t have the time so I ordered one. Should be here soon. I would like to get started on my code before it gets here.

So my question(s) is/are; what are the input values/ranges for the nunchuck axises? I’m assuming z button and c button are 1 or 0(is this correct?), but what are the accel and joy ranges? I see Adrian (in his post) listed a rang of 400-650, and Gabriel mentions 0-1024.

If using servos, is the best method to use the map function or write a task function similar to that of todbot?

Example : http://todbot.com/blog/bionicarduino/

downloaded nunchuck sketch

float tiltx = nunchuk.accelX(); // x-axis, in this case ranges from ~70 – ~185

tiltx = (tiltx – 70) * 1.57; // convert to angle in degrees, roughly

accelpulseWidthLR = (tiltx * 5.6) + minPulse; // convert angle to microseconds

Also do the ranges change if your using a third party nunchuck vs. a Nintendo nunchuck?

Thanks
