A perfect start for the new maker.

Learn by creating a gadget that records your environment data to an open-source Web logging service (EmonCMS). Access it from your browser with a full-featured dashboard.

This course is designed for beginner makers. I will help you get started with the basics of creating circuits with the Arduino prototyping board, and by the end of this course you will have an Internet-connected home environment monitoring gadget, build with your own hands!

The only prerequisite is a basic understanding of concepts like voltage, current and resistance, and ability to download and install software on your computer. A very basic understanding of programming is a bonus, but not absolutely necessary.

Along the way, you will learn about programming, sensors, and communications.

The course is split in three parts:

  • Part 1 is an introduction, which will gently help you create your first circuit and open your appetite for more.
  • Part 2 contains a primer on making with the Arduino, focusing on the Integrated Development Environment and the sketching language.
  • Part 3 is about making Jing. Jing is the environment monitoring system that you will put together piece by piece, and line by line.

Here's what you're getting:

  • Arduino: Make an IoT Environment Monitor video course.
  • 5 hours of on-demand video.
  • Downloadable code sketches for all experiments.
  • Circuit schematics with video assembly instructions.
  • Lifetime access
