The first thing I think what will arrive first be a thumbsticks, and thinking becomes true!
Well, the Arduino Pro Micro what I bought came maybe as last item, but for now I use my own same Arduino Pro Micro.
As first thing what I need to do is make a computer to see Arduino as Gamepad! Not all Arduinos/Atmel chips support this, but Pro Micro/Leonardo with ATMega32u4 support custom HID Descriptor. Nice!
So, Im going to make a custom Gamepad library for Arduino! Now I need to search a Gamepad HID descriptor, I dont found alot of sources, but its enough! (Source)
Now just only a implement functions to library!
And its done!
The next thing what is needed is of course a Arduino Code implementation, you can see my example HERE. Its contains a calibration (for good center) and formatting valid values for descriptor!

Video with playing Mirrors Edge: (I used a X360CE to patch XINPUT etc. for make GamePad working in game (Game supports only XBOX360 Gamepad)):
So that is all for today, i hope you enjoy this little article! Next article will be maybe about solving a problem of lack digital inputs, its not enough or about thing what will arrive home next!
