Questions about where are I2C pins on Arduino Diecimila

(Sorry for my English)
Hi guys, I've searched on internet, and didn't found nothing.

I would like to know where are the I2C pins (if there are any) on the arduino Diecimila, and, how to use them (but I can google that).

Thanks in advance.


They should be on pins A4 and A5

Okay, thanks.

And, if I want to use a 7-segment HT16K33 Backpack (adafruit), is there a particular order for plugging the SCL and SDA ports?

It should be the same as for an Uno

okkay, thanks men!
I tell you if I have problem

Okay, thanks, it works!
