Light-Following Robot with Vincibot | Clean Conditionals Using elif (Python Lesson 11)

In this lesson, we turn Vincibot into a **light-following robot** using its left/right light sensors, then **refactor nested if-else statements into a clean `elif` chain** for better readability and fewer mistakes.

## What you’ll learn

* Vincibot hardware basics: dot-matrix screen & dual light sensors
* Reading light intensity with `get_brightness("left"|"right")` and comparing values
* Turning right/left based on intensity difference; going straight when balanced
* Stopping in darkness
* Refactoring: nested if-else → `elif` chain

## Tips

* Tune the threshold (e.g., **30**) to your lighting conditions.
* Order `elif` conditions from strongest to weakest to simplify debugging.
* Test with different light sources (lamp, phone flashlight, etc.).
