The Huzzah ESP8266 module is an inexpensive microcontroller with WiFi capabilities. It can be programmed with the Arduino IDE so that you don't need a separate microcontroller! This device gets the latest weather information from DarkSky.net and displays it on a 1.3" monochrome OLED display.
Note on difficulty: this is an intermediate level project and involves running a PHP script on a web server to parse data from DarkSky.net before it gets read by the Huzzah. It's helpful to know some basics about PHP and web servers before starting this project!
This project was created by Daniel Eichhorn and the code was forked to work with Adafruit hardware and libraries.
The weather icons were created by Alessio Atenzi.
Dano Wall designed the lasercut enclosure.
