Hello I am trying to figure out how to control a brushless motor to go both directions with an arduino. Ultimate goal is to use it for ROV control. I hope someone can point me to some code.
Thanks

You will need a brushless electronic speed controller. "ESC". If you get ones for a car they will have a reverse function. Controlling it from an Arduino is very simple with the servo library.
For example. ( but maybe not suitable for your application, depends on motor and load )
If you want torque at stationary or low speed you need a sensored motor and an ESC that
handles sensors.
