Abstract

My favorite things in life are cats 🐈, computers 🖥 and crappy ideas 💩, so I decided to combine all three and make an IoT (Internet of Things) litter box using a Raspberry Pi and JavaScript! If you have ever wanted to build your own IoT project, but didn’t know how to start, then this is the talk for you.

Together, we are going through how I set up my IoT Litter Box from start to finish. Including how to setup Node.js on a Raspberry Pi, how to connect sensors to a Raspberry Pi, and how to read the sensor inputs with Node.js.

About Joe Karlsson

I am a software engineer turned Developer Advocate at MongoDB. I come from the frozen tundra of Minneapolis, Minnesota (and yes, it does get really cold here, and no, not everyone here has the accent from the movie, Fargo). I've been primarily a Node and JavaScript engineer and have been writing, teaching, and talking about code my entire career. Sharing what I know and continuing to learn about programming is truly the thing I love doing the most.
