I want to make a steering wheel without ffb, but for receiving feedback from game; I wanna use 2 rumble motors inside the wheel's handles. I'm not a coder or electrician. That's why I help at this simple project.
So, if we go back to the topic's title, you can consider this wheel as a normal gamepad. How can I make this possible?
That makes no sense. You cannot connect a motor to an Arduino without a driver or some sort. A "logic-level" FET would be a start, but it may be easier for you to use a module containing the FET and associated parts.
you came to wrong forum, you should write to racing game developer and ask they to make gamepad motor interface or whatever you want to have while playing.
