WeatherLEDs

Shows daily weather forecasts on a RGB LED stripe connected to an ESP8266.
The next 8 days are represented each by one animated, colored pixel.
Uses local weather forecast data from OpenWeatherMap (formerly used DarkSky API).

Colors

  • Yellow: sunny.
  • Fading between yellow and white: cloudy (more yellow or white depending on cloud coverage).
  • A darker steady white shows fog.
  • Blue: rain, the heavier, the more it flickers.

(Should be pretty self-explanatory)

Requirements

  • ESP8266 board such as NodeMCU, Adafruit Huzzah Feather or WeMos D1 mini.
  • A NeoPixel compatible LED stripe with exactly 8 LEDs.
  • PlatformIO (or the Arduino IDE).
  • OpenWeatherMap API account (you only need the free account tier)

When using the Arduino IDE, install these:

How to use

  1. Connect the LEDs to +5V (red) and ground (black), the third data line goes to GPIO3 (RX on WeMos D1 mini).
    • Note: on ESP8266, only GPIO3 will work.
  2. Enter your WiFi credentials, location and the OpenWeatherMap API key into the code (definitions at the top).
  3. Connect the ESP8266 and program it:
    • with PlatformIO: platformio run -t upload (or the run/upload button in VSCode).
    • or with Arduino IDE: open WeatherLEDs/WeatherLEDs.ino and click the run/upload button.

Enclosure

A not-so-perfect 3D printable enclosure (pictured above) is included (3D print parts/WeatherLEDs_V8.stl), suitable for a stripe with 8 30mm spaced, 5x5mm quadratic WS2812B RGB LEDs, and a WeMos D1 mini board.
