Hi, friends! 👋🏻 Welcome to the .NET IoT for Beginners Series.

In this video series, Microsoft Sr. Content Developer Cam Soper explores the use of .NET on common single-board computers, such as Raspberry Pi, Orange Pi, and Hummingboard. The series focus is using the .NET IoT Libraries to control LEDs, relays, sensors, displays, and more. In this introductory video, Cam shows how to prepare a Raspberry Pi for use with .NET, where to find the documentation, and how to run a quick demo using a Raspberry Pi Sense HAT.

Remember, even if you don't have a Raspberry Pi, most of the concepts in this series can be applied to other single board computers!

In part 2 of the series, Microsoft Sr. Content Developer Cam Soper shows how to deploy, run, and debug .NET code on ARM-based single-board-computers (such as Raspberry Pi, Orange Pi, ODROID, and others). The video covers the self-contained deployment process and how to copy the published files to the device. Cam also explains how to remotely debug the app on the device using Visual Studio or Visual Studio Code.

Welcome back, friends!

In part 3 of the series, Microsoft Sr. Content Developer Cam Soper shows you how to use the pins on an single-board computer (like Raspberry Pi) to control external devices. Starting with the basics of the General Purpose Input/Output (GPIO) header, Cam demonstrates how to use a breadboard and a GPIO breakout board to create a simple LED circuit. Then, using the .NET IoT Libraries, he shows how to blink the LED. After that, he takes it up a notch by demonstrating how to use a relay to control a larger device like a light bulb or a fan. Join Cam as he walks you through this IoT equivalent of "Hello, World!"

In part 4 of the series, join Microsoft Sr. Content Developer Cam Soper as he continues his exploration of using his Raspberry Pi's General-Purpose Input/Output header in this video. This time, Cam shows you how to use the same pins for input, starting with a demonstration of how to detect open and closed circuits using a magnetic reed switch. He then moves on to a laser setup, where he uses a voltage divider to detect when the laser beam is broken. Cam finishes the video by accepting a challenge from his son: to send and receive Morse code messages using laser light! Join Cam on this IoT adventure and learn how to create practical applications using single-board computers!
