16x16 Weather Display

A little program to display weather data on a 16x16 LED Matrix. The display switches between a weather pictogram and the current temperature. Weather data is obtained from OpenWeatherMap - you need a valid API key to use the program (for further setup steps see section Config below).

Hardware Basis

• ESP8266 D1 Mini Board
• 16x16 NeoPixel LED Matrix
• Power Supply MicroUSB 5V

Used Arduino Libraries

• FastLED
• ArduinoJson
• ESP8266HTTPClient
• ESP8266WiFi
• ESP8266WiFiMulti
• WiFiClient

Setup

• The program needs a WiFi connection to work. Enter your WiFi SSID and password for the STASSID and STAPSK defines in the code.
• To obtain weather data, you need to set up a valid API key for OpenWeatherMap. You can do that here. Once you have your key, enter it for the APIKEY define in the code.
• Make sure your microcontroller is hooked up to the LED Matrix correctly - you may need to adjust the LED_PIN to your specific setup. This pin should connect to DIN on the LED Matrix.
