## Arduino-based puzzle modules

> [!NOTE]
> Because of the poorly designed hardware (21-22) used during development
> (23-24), all puzzle modules ended up being developed using Arduino boards.

The Arduino based puzzle modules also use CMake with the
[Arduino-CMake-Toolchain][arduino-cmake]. To build any of these puzzles, make
sure you have done the following:

- Install the official Arduino IDE
- Open "Tools" > "Board" > "Board manager"
- Install the "Arduino AVR Boards" package (1.8.6 works at the time of writing)
