Lesson 55: Create a Dynamic Rainbow With Neopixels in MicroPython

This tutorial covers creating a running rainbow pattern on a NeoPixel array using the Raspberry Pi Pico W and MicroPython:

• Wiring Setup: Connect 5V, GND, and Data pin to GPIO pin 0 on the Pico W.

• Concept Explanation: Create a running rainbow pattern by incrementing HSV values and applying them to each pixel.

• Code Implementation: Use a function to convert HSV to RGB. Implement nested loops to cycle through the HSV color wheel and update the NeoPixel array.

• Demonstration and Testing: Display the running rainbow pattern and provide troubleshooting tips.

• Homework Assignment: Experiment with new patterns and share results with the community.
