Project Details

Description

The Brolli project is an Arduino program designed for an ESP8266 module, NeoPixel LED strip, and Wi-Fi connectivity to provide a visual indication of hourly precipitation probability for a specific location. It fetches weather forecast data from the Open Meteo API and uses NeoPixel LEDs to display the information.

Hardware Components

• ESP8266 Module:

  • Selected for its compact size and Wi-Fi capabilities, serving as the central unit to fetch weather data.

• NeoPixel LED Strip:

  • Chosen for its individually addressable and vibrant RGB color capabilities.

Data Retrieval and Integration

• Open Meteo API:

  • Integrated the Open Meteo API to retrieve weather forecast data for a specific location, providing access to precipitation probability information.

Data Processing and Display

• JSON Parsing:

  • The program parses the JSON response from the API to extract hourly precipitation probability data for display on NeoPixel LEDs.

• Looped Operation:

  • The program operates in a continuous loop, fetching and displaying updated weather information every hour.
