12-Key Rotary Macropad

Motivation

When debugging programming, function keys like F8 are frequently used. However, Macs with TouchBar make it difficult to touch type function keys, making them quite inconvenient to use.

To serve as a substitute for the function keys, I created a macro pad.

Additionally, since I had extra joysticks, OLEDs, and rotary encoders lying around, I decided to incorporate all of them into the macro pad.
