About
===
This software enables you to display the weather, current time and the bus' next departure on a Display.
This project is a compilation of different components:
* Weather from http://openweathermap.org/ (see [the weather documentation](doc/weather.md) for more details)
* Swiss Traffic Information from http://transport.opendata.ch
* Time (included in the Spark Core firmware)
**You can remove, add or extract any of the components and create your own project. Share your mix if you like.**
### Display
The colored LED shows when it is the right time to leave and catch a bus. (Green=Good to go, Orange=Run!, Red=too late)
The display shows the time, weather, temperature and next bus departures. The position are configurable in the code.
### Hardware
The required hardware is:
* Spark Core (https://www.spark.io/)
* 16x2 OLED Display (http://www.adafruit.com/products/823)
* Some wires
### Circuit Diagram
Putting it together is quite simple:
Circuit layout:
See also the photos of my wiring [first](doc/wires1.jpg) and [second compact version](doc/wires_compact.jpg).
## Getting started with the firmware
You have to change some settings in [application.ino](firmware/application.ino), in the method ``setup``.
Firstly, setup the display acording the your wiring:
lcd = new Adafruit_CharacterOLED(OLED_V1, D0, D1, D2, D3, D4, D5, D6);
Set your location (e.g. London,uk) and replace your api key from http://openweathermap.org
weather = new Weather("Bern,ch", httpClient, "YOUR_OPENWEATHER_API_KEY");
Set your station and adjust the URL (from, to):
transport.init(lcd,
"/v1/connections?from=Wabern,Gurtenbahn&to=Bern&fields[]=connections/from/departure&limit=6",
httpClient);
### Build and deploy
You must install [spark-cli](https://github.com/spark/spark-cli).
cd firmware
spark cloud flash 1234567 .
This will build and deploy the source in the spark cloud. (You must replace the device-id `1234567`. )
You can also configure and use the `Makefile`.
## Used libraries
* [HttpClient](https://github.com/nmattisson/HttpClient) for making http request
* [ArduinoJson](https://github.com/bblanchon/ArduinoJson) for parsing json response from http://openweathermap.org/
* [Adafruit_CharacterOLED](https://github.com/ladyada/Adafruit_CharacterOLED) Arduino for the 16x2 Display, I fixed some imports
Remarks
----------------
* The display [Monochrome 128x32 SPI OLED](http://www.adafruit.com/products/661) might be a better choice, as it gives more flexibility for drawing, uses less wires and is much cheaper.
* Daylight Saving Time ("Sommerzeit") is currently not detected automatically.
