DIY Wheel with Simhub & Nextion Display

Hejhej,

I was planning my projekt for my new Racing Wheel and I stumbled over the following sentence on SimHub Wiki:

"Arduino Pro Micro : The arduino will emulate a TTL and allow RGB LEDs or buttons to be added"

Now, I plan to add rgb leds AND buttons and I am wondering, if every free pin is free to use.
Will this wiring plan I have in mind work out?

Thanks everyone for your help!

Are you planning to use the push function (like a button) of your encoders? I don't see those anywhere.

You can use the RX0 and TX1 ports aswell, they just won't be displayed in the Simhub Arduino setup tool.

For information, I have added the wiring diagram of my own project wheel. 12 buttons (including shifter paddles), 5 encoders and 24 LEDS. I didn't have enough pins to utillize the push function of my five encoders so I've left those out.

rx0 tx1 for nextion display. 2,3,4,5,6,7 for 3 encoders. 8,9 button col 1&2. 10,16,14,15,a0,a1 for button row 1-6. a2 for leds, a3 for single clutch paddle.

the weird thing is that mine did not work on one ardiuno because the led's and nextion draw to much power from it..........and i did read there where more ppl having that. tho if it works than great :).
BTW your link i knew allready that where i got it as well.

I made one with a screen - used a vocore and an LED strip.
Fun project, but I never got round to finishing it. It needs the handles to be wrapped in alcantara or something, and the front re-printed without the printing pattern.

Everything works, encoders, pushes, switches etc.

Yea man, it works a treat. I made sure I made a wiring diagram, so that I wouldn't make mistakes while wiring the thing up. Worked pretty well! The wiring diagram is in this thread too by the way, if you want to check it out.
