Yes i am using Wire library
Sorry i could not make myself clear
I know arduino I2C address is 127 but that is basically the I2C adress of the controller but controller I2C address can be changed by setting TWAR register. So i want to know it their is a funtion or sketch in arduino 1.0 IDE that can give me the access to the TWAR register of Atmega328.
Thanks in advance.
