It’s been way too long, but the next in the series of IoT «Build-along-at-home» videos is done. In this edition I will show you the «Hello World» project for interacting with the IO ports on your Raspberry Pi. Please click here to watch the video and as always, comments and questions are appreciated and welcomed! If you are the type (like me) who just likes to figure stuff out on their own, I have heavily commented the code for you so you can get started quickly without the video, but it will help you with the hardware assemblies! Also I am already working on the next projects, using the moisture sensor (the original project), and another future project using a sound sensor to illustrate some of the «threshold» principals of IoT sensors
