**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.
