Hello. Right off the bat I would like to say I have not prior experience with arduino, although I have experience with programming, unfortunately not in USB/HID programming but I'm willing to learn it for this project. First I would like to explain a use case, so I started playing in gran turismo 5/6 (ps3 title) with a wheel and I would like to use handbreak accessory (thrustmaster tss handbrake sparco mod+) the issue here is that the handbreak will not work because it's too new for the game or any ps3 title in that matter.
So I have started thinking why not to use arduino as somewhat a proxy which would convert signal from handbreak to connected gamepad analog (set in the game) and simply passthrough signals from usb port where gamepad is connected. Essentially arudino would mimic a signal from handbreak as pressed analog signal.
So the main question for now is which arduino board would be the best for it and which additional modules I would need to purchase to make it work ?
