Hi. I am tring to get the nunchuck working with the Arduino for displaying the readout in the serial monitor,

Is there a reference for pin numbers from previous models as there is a lot more i/o on the Mega.

I was wondering if I have the wrong pins connecting to the nunchuck, I am using analog in pins 4 and 5 but the readout shows all zero's Any suggestions.

The I2C pins are in a different location on the Mega. On a standard Arduino they're on Analog 4 & 5, on the Mega they're on digital 20 & 21.
