Two of the analog pins are used as digital pins, and those pins are set to HIGH and LOW to emulate +5V and Gnd.

I noticed that the adapter only plugs into analog input pins. In most other websites with tutorials on this I see it plugged into ground and 5v as well. How does this work? What is the difference?

Dude, is it possible to hook up a classic controller or a motionplus to one of these? that would be SO FREAKING AWESOME!!!!!1!!!ONE!

Yes, it works with arduino uno. I can tell you this first hand.

I just purchased two of these adaptors a few minutes ago, and then started reading these comments.

Q) will the adaptors work with an Arduino UNO?

Hey Todbot thanks for sharing. :-)
Do you think it’s possible to code the Arduino to store the data and than play it back at the exact same rate again and again? I’m trying to control a camera and record the movement – and than repeat it.

I am looking for input on conecting my nunchuk to my Arduino Uno R3. For something that a lot of people are getting to work and seems so strait forward, I am having difficulty with it. I have searched the net and started with Arduino 1.0 and Gabriel Bianconis library, when that didn’t work I went back to Arduino 0023 and tried your sketch. I get the same results. So it must be something I am doing wrong.

Printing data to com port:
I am using a wiichuk adapter, – to grnd, + to 3.3v, d to A4, and c to A5. When I upload the sketch nothing happens, if I unplug the nunchuk i get a tx light and serial communication but only defult data, with Gabriels library I get defult data (he says indicatds miss-wire, but confirmed my wireing was correct) with your library I get labels such as zbutton but no data behind it.
When the nunchuk is pluged in I get no Tx or Rx leds flashing, I have tried trouble shooting but with so few parts to swap out I’m looking for input and suggestions.

Thanks
Chris

Hi Brandon,
While both USB and the Wiichuck use four wires to deal with power and communications, the communications protocols are very different. The Wiichuck uses a protocol called I2C, which is very different than USB. You need something that converts between USB and I2C. And an Arduino is a pretty good USB-to-I2C converter.

Do u have to use a Arduino? Cause i just wanted to make a wii nunchuck as a mouse. I took apart a mouse and saw that the USB only has four wires. I was thinking if i could connect those four wires to the 4-pin header and use the nunchuck as a mouse
