(Asked by: username_0 on 2014-12-12)

I am building up a robot and I want to use 2 NXT connected together because I need more than 3 ports A,B,C. So my question here is: When I write the code, is there anything different I have to do?

For example do I write the same code I would use for 2 NXT and just connect them together or do I have to do something more than this?

I found a way to connect them but I have not found examples yet of the blocks (nxt code software).
