Lesson 34: Convert HSV to RGB in Micropython

This tutorial covers converting HSV (Hue, Saturation, Value) color values to RGB (Red, Green, Blue) values and displaying them on an RGB LED using the Raspberry Pi Pico W:

  • Introduction to the HSV Color Wheel: Explains the HSV color wheel and its use for smooth color transitions, especially for visualizing temperature data.

  • Project Setup and Goal: Recap of the weather station project and the goal of adding RGB LED color representation for temperature.

  • Understanding HSV to RGB Conversion: Describes the HSV color wheel’s mathematical representation, zones, and RGB conversion.

  • Algorithm Development: Creates a function to convert HSV to RGB values and sets up the RGB LED with PWM on the Raspberry Pi Pico W.

  • Code Implementation: Walkthrough of Python code for PWM control and HSV to RGB conversion, including a library function.

  • Practical Demonstration: Shows RGB LED color changes based on HSV, and assigns the task of integrating the LED into the weather station project.
