Raspberry Pi Pico Tutorial - 2.💡Control Multiple LEDs with MicroPython using the Wokwi simulator
In this second tutorial of our MicroPython + Object-Oriented Design series on the Raspberry Pi Pico, we take our `Light` class to the next level! You'll learn how to create multiple instances representing different LEDs, wire them up using the **Wokwi simulator**, and control them with a loop and an array in clean object-oriented Python.
🎯 *What You’ll Learn in This Video:*
How to connect multiple LEDs (with resistors) to Raspberry Pi Pico pins using Wokwi
How to reuse your `Light` class with multiple instances
How to manage multiple outputs using a Python list and a loop
Object-oriented thinking: encapsulation, reusability, and scalability of hardware components
🧰 *Tools & Requirements:*
[Wokwi.com](https://wokwi.com) (Online Raspberry Pi Pico simulator)
Raspberry Pi Pico (if you want to try it on real hardware)
MicroPython firmware & Thonny IDE
Basic understanding of GPIO and Python classes
