5th Encoder

Hi All, I am completely new to Audrinio and tried the facebook groups, but no help has been offered.

I have a button box and im using the attached Sketch.
Is it possible to change the sketch to add a 5th Rotary encoder, I don’t mind losing a few buttons in the sketch and changing the board from a pro micro to an Uno or Mega if I have too.
Also, as a side question, my LED toggle will not light when switched on. I have connected the led to the 5v and chained it to the on connector (sorry for my terms, I have no experience )

The Sketch is,
//BUTTON BOX
//USE w ProMicro
//Tested in WIN10 + Assetto Corsa IRACING
//SKULL SIMGEAR

#include <Keypad.h>
#include <Joystick.h>

#define ENABLE_PULLUPS

Sure, if you have spare pins. Just modify these lines…

#define NUMROTARIES 4

rotariesdef rotaries[NUMROTARIES] {
  {0, 1, 24, 25, 0},
  {2, 3, 26, 27, 0},
  {4, 5, 28, 29, 0},
  {6, 7, 30, 31, 0},
};

Also, as a side question, my LED toggle will not light when switched on. I have connected the led to the 5v and chained it to the on connector (sorry for my terms, I have no experience )

I can't see any code in your sketch to toggle a LED?
"on connector" makes no sense, sorry. Say which pin of the Arduino ProMicro. Even better, draw a circuit diagram.
Do you have a current limiting resistor?

Hi
thanks for the reply, as ,mentioned i am completely new to this so please accept my apology in my terms.

I have two, toggle switches with a led light then end, i was hoping for them to light when on. and no i dont have a current limiting resistor

Ok the Pro Micro has no spare pins, so i could use a Mega ? not how do i modify, add the pin numbers like the others ?

hi

i really dont know to modify the lines, could you help please.
