• The software setup section's code fences seem unbalanced here. Ensure the opening and closing ```bash fences correctly wrap the repository commands.

• The project structure is listed twice in the README, which can confuse readers. Remove the outdated file tree or consolidate it into a single accurate diagram.

Using delay(200) for button debouncing blocks the main loop and may cause missed time updates or button presses. Consider switching to a non-blocking debounce implementation using timestamps.
