If you are the lucky owner of the Microsoft Azure IoT Starter Kits containing Adafruit Feather, I've created a step-by-step guide for you to integrate with Azure. The aim of this mini project is for the Adafruit Feather to communicate with to the Microsoft Azure IoT Hub. Adafruit Feather should be able to send telemetry messages and also respond to commands sent to it by the IoT hub. Enjoy. and don't forget to provide feedback.
