Logitech shifter usb arduino adapter

Hi, firstly I am really sorry if this is the wrong spot to post, if it is please direct me to where I should move this thank you.
I am attempting to hook up my logitech g29 shifter to an arduini pro micro (but in IDE it's an arduino leonardo) and I'm following this tutorial,(DIY LOGITECH USB SHIFTER ADAPTER DRIVING FORCE - YouTube) [DIY LOGITECH USB SHIFTER ADAPTER DRIVING FORCE by amstudio]

I have checked for continuity so I know my solders are good so this is definitely a coding error on my part. I have installed the correct library (joystick) and I am getting stuck with error compiling for board arduino leonardo. I used to code it as a pro micro but that bricks the bootloader and I end up resetting and if it's coding it as a leonardo I have no issues with other programs. Again, I am very new to this forum so I apologize in advanced if this is not formatted or posted correctly.

Thank you for your patience to whoever reads this! :slight_smile:

Welcome aboard. I am of the opinion a good solder connect does not make the circuit correct. Post your schematic, not a frizzy thing. It appears to work on some systems, that tells me the code is at least close.

True, I'll post the schematic once I figure out. I also can't verify the code myself though, could wiring effect that too?

Short answer yes!
