Is there anyone successfully connected two modules Arduino Nano through i2c bus?

 My test setup is  [NANO_MasterReader] <---> [NANO_SlaveSender]
Probably Slave_Sender breaks communication.

Connection [NANO_MasterWriter] <---> [NANO_SlaveReceiver] works fine.

Hi Gergio,

You might want to have a look at http://code.google.com/p/codalyze/wiki/CyzRgb which is a open source implementation of the BlinkM. It implements a I2C slave. As I2C master you can use any of the BlinkM demo programs from http://thingm.com/products/blinkm.

I can confirm that using the duemilanove it works perfectly in both directions using the standard wire.h
Believe me, Mike, I calculated the odds of this succeeding against the odds I was doing something incredibly stupid[ch8230] and I went ahead
