Just some quick info on my knowledge.
In the past I have built several button boxes using button matrix,encoders,and pots for gaming and various other programs. Ive only used the Nano once, several Pro Micro's and a UNO once for force feedback for my racing sim setup. I have not ever done the programming side of Arduino, I used MMJOY as it was adequate for my needs.
Now what Im trying to do is make a midi foot controller to use with my DAW and Amp/pedal sims for guitar thru USB.
My plans are to 10 momentary foot switches with LEDS only for 7 of the switches to show activated switch or off and 1 pot for an expression pedal.I plan to also use the Pro Micro since I already have it extra. Plus another on/off/on switch for switching layers.(used the way Ill show in example)
But for now Im having trouble trying to understand how I need to wire all this up with the amount of controls I want, meaning Im not sure if I have enough inputs. Trying to keep it budget since so far I already have the parts from the parts box so as of now cost is $0.
I was looking at this example from github,easy to understand diagrams and such but like I said cant figure out how to count for the extra buttons I was wanting to add.
Please some info,links any help would be appreciative.
Example Diagram from github: Also github link for the what I want but just more switches than the author is using.
