Скачать или смотреть **Raspberry Pi Pico/MicroPython Tutorial #8 |🔘 Lets push some buttons! Event handlers in OOP**

In this eighth episode of our *Object-Oriented MicroPython on Raspberry Pi Pico* series, we move beyond outputs and explore *inputs* by adding *buttons* to our application. Instead of continuously polling button states, we introduce the **event handler pattern**, where button presses and releases are captured and sent back to their handlers in real time.

You’ll learn how to design a *Button class* that integrates seamlessly with your project, and we’ll build a simple application with *4 buttons* that turn pixels on and off in a NeoPixel light strip. We demonstrate how it works in both the *Wokwi simulator* and **real hardware**, showing the power of OOP design in embedded systems.
