Скачать или смотреть Raspberry Pi Tutorial 4 -🌈 Add a Neopixel Light Strip with Polymorphism | OOP on Raspberry Pi Pico

In this fourth video of our *Object-Oriented MicroPython on Raspberry Pi Pico* tutorial series, we level up our LED animations by adding a *Neopixel RGB light strip* to our project. Using *subclasses* and **polymorphism**, we can treat the light strip just like our regular LEDs—meaning it drops right into our array of lights and participates in the animation **without changing a single line of the main animation code**.

Along the way, we’ll also review and explore key OOP concepts in Python, including:

*Classes and Objects*
*Attributes and Methods*
*Encapsulation*
*Inheritance*
*Polymorphism*

By the end of this video, you’ll understand how to extend your code for new hardware in a clean, modular way—no messy rewrites required!
