This is my first PCB project : a simple macropad with 6 switches, a rotary encoder, an oled display and a microcontroller. The OLED screen will display animations based on what switch is pushed, leds will be illuminating the whole macropad with predifined colors animations. The rotary encoder is going to be used to change the volume and to change the key shortcuts mode by clicking it. The switches will either regulate my spotify playlist (first key shortcut mode) or other shortcuts based on what work I complete.
the whole schem is really not clear to understand because it was my first one ever
