I've been running a small workshop at work to show IoT Edge basics for a few months. It has always been a lot of fun both for me and the assistants and I've finally found time to clean up a bit the github repo so I can share it with all of you.
The tutorial basically shows how to create an Iot Hub and a properly configured IoT Edge device and then deploy an application that will perform facial recognition. The whole version includes a Function that sends DirectMessages to the device to trigger a police alarm (using http hooks and a Sonoff relay), but this last part is still not properly documented (sorry!).
Of course, pull requests are super welcome :) Cheers!
