Arduino Remote Controll

Hi,
I have a USB adruino and
I have a PhotoCam with 3 pinns in a RemoteControl hole.

I need to shorten 2 of them for focus and then all 3 of them to shot a picture.

So i connect them with 3 wires to arduino ANALOG pins 0,1,2

so how can i build in VVVV a patch to shorten those pinns???
which code can i use to upload to arduino?

everything i saw here (multisignal_ascii_sender or firmata) seems to make something else…

the one thing i found out, i have to put a resistence between the cam and the board to save both of them from burning…right?

To simplify the question, can i use the arduino board as a relay?
Can i control it via VVVV?

Update:
arduino cant be a relay but it can control an external relay.
So i will do.
