Runcam2 control from Arduino?

Hello, im currently in the process of making this DJI Mavic Clone Foldable drone frame (wider body, higher ground clearence,bottom access plate) Remix by mwilmar - Thingiverse

After talking to the creator of this design he said that for the gimbal he uses a desassembled Runcam2 and a Arduino mini pro and triac to control the shutter and power. I have a Runcam2 that I can use, but this is my first interaction with a Arduino board. If someone could help me better understand how I need to wire the Runcam components to the Arduino board? I would greatly appreciate it.
