Show HN: Arduino traffic light(table-driven design)

I started with a very simple Arduino project: two traffic lights controlling a junction (six LEDs).

I refactored it by using arrays and small, modular functions, so it’s easier to read, modify, and extend.

Why refactor the code?: less repetition, clearer intent, easier to change timing/logic by editing a table instead of code paths.

Feedback welcome—especially ideas to extend it.
