Schematics of the PCB

–––––What i learnt–––––
I learnt some things about the micro controller and PCB designing. im new to this so i had to research this a little to start to understand the project. I took reference from another project as i found its design similar to what i wanted. i read through all of their devlogs to understand the procedure of doing things.

–––––What i did–––––
I made the schematics for the PCB excluding the oled panel. i couldn’t find how to get it in KiCad. spent some time understanding matrix for further projects. i also learnt about rotary encoders.

–––––What im going to do–––––
Remove the expander and directly connect everything to the micro controller. add the oled pannel and connet it also
