Is it possible to daisy-chain Arduino?

Is it possible to daisy-chain more than one Arduinos on the IC2 Interface? If so, is there some type of addressing (as with TCP/IP) used to accomplish this?

One has to be "master", and the other "slaves" (and each has an address) - check out the Wire library:

:slight_smile:

Yes have a look at http://www.arduino.cc/en/Tutorial/MasterReader to get started.

Thank you.
