Hi,

I try to interfacing arduino with this controler for servo motor : SD-20. SD20
It's an I2C protocol and i don't know nothing about it.
Any one can point me about some code or exemple for this type of interface ??

Thank's for your help.

The I2C bus is also called the TWI (Two-Wire Interface) in the ATmega168 data sheets.

Lucky for you, the Arduino environment comes with a library that implements all the tricky stuff for you. It's the Wire library. You can probably do a search of the forum to pull up any other info you might need on it. (:
