Wiimote Extension Connector Pin-Out (Nunchuck, MotionPlus and Classic Controller)
The Wiimote uses I2C to communicate with the extensions. Here is the pin-out of the connector so that you can connect to an Arduino or a Netduino.
Connect VCC (red) to 3.3V, GND (black) to ground, SDA (green) to analog 4 and SCL (yellow) to analog 5. You can ignore DEVICE DETECT (white).
To connect, you can stick in wires (like I did on other pictures) or use a simple adapter like this one todbot.com/blog/2008/02/18/wiichuck-wii-nunchuck-adapter-...
There should be 2.2K pullup resistors for both SDA and SCL.
You can use HydraMF, my open-source library for .NET MF. Binaries are available on Nuget (nuget.org/packages?q=hydramf) and source code on Bitbucket(bitbucket.org/aalmada/hydramf/).
