TiltSensor / Beer Me is an introductory IoT project that uses a Raspberry Pi 2 Model B, a breadboard, wires, 3 resistors, and 3 LEDs. The code is open sourced on GitHub and this video walks through how to setup this project. The items that need to be created in Azure are an IoT Hub, Service Bus Namespace and Queue, Stream Analytics job, and a Logic App. This was developed for a Windows 10 UWP app using C# and Visual Studio 2015.
