I got my hands on a vex V4 brain and key and don’t know what to use to program it
Look at this page at the bottom - Cortex
i dont understand i am new to vex
Is what you asked. I pointed you to resources to software to program Cortex (also referred to as V4). Please look at the resource and then reframe your question for clarification.
under cortex there is a few options witch one do i use?
Which ever one you want to use. I’d recommend RobotC or PROS.
I would use context here - new to VEX - robotC has a lot of more “formal” support from CMU lessons. But others may have opinions.
thanks for the help to both of you
You can find many videos on Youtube on setting up and using RobotC . Hope they will help you get started. there are also many tutur web sites on the web.
