I like this, I find the Wii chuck easier to use the the normal dual joy controllers often used for bots, and other RC projects.

Hi TrogFlin,
What speed is your Serial Monitor set to? It should be 19200.

I am getting gibberish when I run the sketch off the nunchuck adapter page. Any idea where I am messing up? Sample output “Á??å?¾¤?Äø¤Å?ô¤Å” The sketch is running and the output changes in response to movement of the nunchuck. Other sketches have fine output.

Hi gameguyz,
The problem was that the sketch used the old version of initializing the serial port (“beginSerial(19200)”) instead of the modern way of doing it (“Serial.begin(19200)”) I’ve edited the sketch above to have that change.

Also, my most recent code about Wii Nunchuck stuff is on the Wiichuck adapter page.

Hi Aaron,
The Arduino Mini uses the same microcontroller processor as the regular Arduino. It just uses the smaller surface mount package form of it.

I’m using the Arduino Mini 04 and wondering what changes must I make in order to utilize this great information? How does the mini perform in speed, compared to the larger chipset.
Thanks for any help.

My brand new Made in Italy Arduino just got here, I connected the nunchuck and it works perfectly. I guess it was my old board. Thanks again for the help.

Alright, will do. Thanks for the help.

Noise on the lines can cause stuff like that. The “Wire” implementation of I2C in Arduino is too simple to do check to see if a device is really there or not.

It sounds like it’s time to try this out on another Arduino or to try a different Nunchuck. This is one of the problems with debugging hardware: if it doesn’t work right off the bat, you need duplicates of stuff to exhaust all the possibilities.

It might be you have an ATmega chip with fried analog in pins 4 & 5. Or maybe the solder connections to them on the Boarduino board are intermittent/bad. Having a pre-soldered & tested Arduino can help here.

I’m sorry to take up so much of your time and comment space, but I just found out that the Arduino is reporting the following:
joy:46,46 acc:49,47,46 but:0,1

…when the green and yellow wires are *disconnected*. I’m absolutely confounded, and I’m hoping it means something you understand that I don’t.

Ok, well I took the voltage down to 4.7 volts, and I don’t get any output, even when swapping yellow and green wires. Do you think it’s a lost cause?
