Where can i declare my Bitmaps (or any variables) ?

Hi !
I just received my Oled Blue/yellow 128x64 screen. I have many bitmaps, so i would like to declare all my bitmap out of the main.
However, i'm not sure if it's necessary to create .h and .cpp files just for that.

What is the best solution to declare only variables out of the main ?

Hi, ty !

I have arround 10 different bitmaps. I'm a beginner with c++. I have to do just a bitmap.h
or i need to create bitmap.cpp too ?

99% are declaring bitmaps in the main.ino , sry but i did'nt watch the 1% video remained yet :frowning:
