Lesson 32: Mobile Weather Station Project

This tutorial covers creating a portable weather station using the Raspberry Pi Pico W:

  • Connecting to WiFi: Import libraries, create a WLAN object, and connect to WiFi.

  • Fetching Weather Data: Use OpenWeatherMap API to retrieve real-time weather data, requiring an API key.

  • Parsing JSON Data: Extract temperature, humidity, pressure, sunrise, and sunset times from the JSON response.

  • Displaying Data on OLED: Set up and connect an OLED display, use the ssd1306 library, and update weather data on the screen in a loop.

  • Powering the Device: Power the Raspberry Pi Pico W with a battery for portability.

  • Code Explanation: Initialize the OLED, connect to WiFi, fetch and display weather data, and set a loop for periodic updates.

  • Homework Assignment: Add an RGB LED to indicate weather conditions based on temperature, humidity, or wind speed.
