Hello everyone! I decided to design my own wheel and I'm trying to understand the diferences in Arduino models for what I need. At first I was decided on using a Mega 2560 as it had a lot of pins and seemed to be the best choice to keep it organized as I don't want to use a button matrix.

I started sketching it on SimHub and came across a warning on the Wiki that said only Micro Pro boards are seen as gamepad on the game itself, any other board would only be visible to SimHub. That means SimHub needs to be open so it can overlay buttons and encoders to the game and I wouldn't be able to use the wheel without it, is that correct? 

Here's what I have planned for it

  • 12 Momentary Push Buttons
  • 7 Rotary Encoders (5 at the front, 2 at the handles for the thumbs)
  • 2 Micro Switches for the Shifters
  • 2 Hall Sensors for the Clutchs (Double Clutch model)
  • 1 Potentiometer to be used as the Bite-Point selector on the Hall Sensors (not exactly sure it will work)
  • A Nextion 4.3" or a VoCore 4"
  • 20 WS2812B LED

That also looks like a handful for the board, would the USB be able to take care of all that energy-wise or should I think of adding an external power source?

I'm new to all this and tried searching around here, RD and Arduino forums before asking but couldn't really figure things out by myself, haha.

Thanks!

no than mean if you use a promicro it will be reconize as a gamepad by your PC like that you can use your buttons on game, if you use another board your button can only used in simhub fonctions like increment luminosity or previous screen for the dash board but they wont be seen by any game

So using a Mega 2560 and sketching it throught SimHub would be pointless for ingame usage? Thanks for the clarification!

you can use the mega for "reading" things like: Led; 7segments module, any gauge, led matrix, LCD20x4 etc....

but for buttons box, rotary encoders or analog axis, you must use a leonardo or a promicro
