Lesson 35: Remote Weather Station with RGB LED Temperature Indicator

This tutorial covers integrating an RGB LED to display temperature data on a weather station using the Raspberry Pi Pico W:

• Project Overview: Build a remote weather station with Raspberry Pi Pico W, OLED display, and RGB LED to visually represent temperature.

• HSV to RGB Conversion: Map temperatures from -20°F (violet) to 120°F (red) to angles on the HSV color wheel.

• Circuit Setup: Connect the OLED display and RGB LED to the Raspberry Pi Pico W, configuring GPIO and PWM.

• Coding: Fetch temperature data, calculate hue, convert to RGB, and control the RGB LED using the HSV to RGB conversion library.

• Demonstration: Display temperature on the OLED and RGB LED, running the setup on battery power.

• Conclusion: Customize the project with different color mappings and temperature ranges, and encourage interaction with the tutorial.
