Hi
I am new to arduino and wish to know how to electrically connect and interface to 3x I2C robot servos using the mega 1280
Have the I2C devices all got the same address or are they different? If they are different you can simply connect all the clock and data lines together. Put a pull up resistor from each of the two lines to +5v (4k7) and use pins, and use PIN20 for the data and PIN21 for the clock on the mega.
If they all have the same address it is more complex so ask again.
Hi Mike,
The spec says the ID address can be programmed and stored in EEPROM, so I guess I have to do that first and then connect all common lines together.
