are you sure here ?
if you rotate joystick 180 degree then no value inversion is needed.

Yes, the Y values vary a bit... other than that. it's nearly the same.
I will try rewiring and see.
Thank you Kohala.
why rewiring? just place joystick with connector on the right
Yes, I will do that.
My bad, I used the wrong word.
I will not rewire, I am changing the joystick direction.
or adjust commando letters on marked place in sketch.
I am having some uploading error in the port.
Sketch uses 1790 bytes (5%) of program storage space. Maximum is 32256 bytes.
Global variables use 102 bytes (4%) of dynamic memory, leaving 1946 bytes for local variables. Maximum is 2048 bytes.
avrdude: ser_open(): can't open device "\.\COM4": Access is denied.
Failed uploading: uploading error: exit status 1
I will fix it and run.
Hi Kohala,
Yes, finally with your help and support I managed to run the LED for one board.
Now into the next level of four board with 31by 31 LED.
I am working to running the single LED on any direction on 31 by 31 matrix.
Can you please give some inputs on how to avoid debouncing? After 0,0 the LED gets disappeared instead of not stopping at 0,0 as like previous.
By the way, please see the picture for the set-up.
how you declare 3 other panel? is it daisy chained?
Initial it was daisy chained.
However, I am unable to write the correct code to work for the daisy chained.
So now I am using separate pins for each panel.
I am repeating the same codes each panel pins.
Please see the code below.

Hello Kolaha,
The code has been fixed, however not by me. My manager hepled.
We kept the same wiring, that is, 3 Digital PIN for each LED panel.
It is working fine.
Below is the code.
Thank you soo much for sharing your knowledge and expertise in Arduino.
//We always have to include the library
#include "LedControl.h"
/*
Now we need a LedControl to work with.
***** These pin numbers will probably not work with your hardware *****
pin 12 is connected to the DataIn
pin 11 is connected to the CLK
pin 10 is connected to LOAD
***** Please set the number of devices you have *****
But the maximum default of 8 MAX72XX wil also work.

Sorry for the late.
