Using the work from profmason.com and an Gikfun I2C Wii adapter purchased on Amazon, we hooked up a Wii nunchuck controller to the OpenCM controller our robot arm. It was surprisingly easy.
We programmed the OpenCM controller to use the two buttons on the back to cycle through the different servos, the LEDs switch to show which one is active. So far we are not using the accelerometer, just the joystick and buttons.
