Arduino -- SC Connection?

I’m wondering how is the Arduino - SC connection?
Can you tell step by step the way to connect Arduino to SC?

I know about Arduino basics but not the SC-Arduino connection.

can someone, tell about a way to find information about my last question (Arduino-SC)?

I think in the SC Book there is not enough information to connect the Arduino successfully to SC, so maybe there is other reference. Thanks.

Lots of resources about SC and Arduino here:

Thanks, it is very interesting, and solved my problem.
