This is the first part of (I hope) 4 where I try to build a software framework for small connected IoT devices. The software is based on the Arduino IDE
In this episode I build a small device which calls a RESTful API to get the next public transportation from my location and starts to warn me with a beeper when the bus arrives.
The episode shows all needed steps to build such a device and other web-services can be used using the same principles.
In the next episode I will connect the ESP8266 to my smartphone to exchange data like access point name and password.
