Hi
I recently made a topic about an LED Latching Button and after getting some guidance, I made a schematic of the final button box I want to make. This is a schematic of the button matrix I want to make. (Sorry for the messiness)
I made this purely off an example in the video below (which was very helpful) so I expect errors.
Video
Parts I will be using:
Push Buttons
Rocker Toggle Switches
Rotary Encoders
Latching LED Push Button
Arduino Pro Micro
Wiring
Thanks in advance!
Do you have a question?
You did try hard to produce schematics. If You use more logic symbols instead of physical representation it had been more clear to read. Pin designations are preferable for all helpers not having the same controller available.
The rocker switches will mix with the other switches. Pressing several buttons at the same time will also produce ghost button signals.
Yes, I just wanted to know if the wiring is correct. I just leveled up so I can now insert the code and libraries. I also forgot to mention that I am very new to coding and wiring so any help is appreciated.

Thanks! I am a bit confused when you say logic symbols, what do you mean by that? For the pin designations, how would I display that? If you can, can you please provide an example so I could possibly remake my schematic. The video does mention ghosting but it says its not that big of a problem if you don't press several buttons at the same time which I won't be doing.
Please post code here, autoformatted in the IDE and using code tags, </>. Many helpers don't download files filling up their computers. Other helpers use none Pc equipment and can't download .ino files.
Zip stuff is not attractive either....
Sorry, I am new around here and still learning.

I am pretty sure that the code is correct since the video did a great job explaining, I am more concerned about the wiring and if it will work.
They're already zero - don't write code you don't have to.
Edit: in fact, you don't need the readings array at all in the code you've posted.
I didn't write this code, it was a base code which I just edited. Is it ok if I just leave it as is or do I have to remove that part?
Often pen and paper works well enough.
Sorry but I don't have any quick example to post.
A symbol for a button could look like _/ _.... Circuits like a rectangular box, the connected wire and the pin designation inside the box. Pin numbers are almost useless. It's the logical function of the pin that has a meaning.
Look around a little. There are plenty of drawings as examples.
An earlier reply... Did You consider it?
What happens when You activate just one button?
Please put some Serial.print in the code gossiping what's happening in the various main functions like CheckAllEncoders();
CheckAllButtons();
CheckAllPotentiometers();
Use serial monitor in the IDE.
You can leave it, but try to understand why it's a bad idea to waste scant resources.
