PIANO

finished some firmare nd part searching !!!

So today so far ive been doing lots of reaserch and tests because when I use one input(button) and one output(light) everything works, but as soon as I add another in/out combo everything breaks has everything on and the buttons turn the lights off which is strange, idk if its code placement or what, ive been rewriting the code using INT instead of uint8_t(i did reaserch appearentlt its better but still breakin) SUCSESS IS AHEAD!!!

Currently made a Schematic,pcb design, as well as a 3d model! ran into issues with Arduino IDE But i hope to fix it so my hours will be logged soon, if not, going to resort to using VS code and transferring it to Arduino
