Learn how to run motors and servo's, build information radiators, communicate with Azure IoT, and even serve up web pages using Microsoft's smallest operating system: Windows IoT and a Raspberry Pi 3. We'll then put it all together to show how you can build a simple Remote Controlled Car entirely in C#.
