hi @tfrshop - welcome to the forum.
I can't read your drawing very well. It looks plausible.
What is the project? It makes a difference as to the selection of the arduino board.
You might like to try building it in the wokwi simulator. That's a great tool to confirm the basic operation of a hardware design and for some projects a way to get the software nearly perfect before you touch any real parts.
