Please note that this tutorial is for the SparkFun Inventor's Kit version 4.1.2 and 4.1. If you have SIK v3.3 or are using parts from the add-on pack, please refer to this tutorial.

The SparkFun Inventor's Kit (SIK) is your map for navigating the waters of beginning embedded electronics. This guide contains all the information you will need to build five projects encompassing the 16 circuits of the SIK. At the center of this guide is one core philosophy: that anyone can (and should) play around with electronics. When you’re done with this guide, you will have built five projects and acquired the know-how to create countless more. Now enough talk — let’s start something!

The print version of this guide is available as a PDF as well. You can view it online as a flipbook or download it to your computer. To download, click the following link below. Keep in mind that the original file size used for the printed guidebook was reduced for the web. While the file size was reduced, it is still about a 31.8MB download.

Choosing a Kit

You should have one of the two following versions of the SIK. If you need a overview of the parts included in your kit, please click on the product link below.

The primary difference between the two kits is the microcontroller included in the kit. The SparkFun Inventor's Kit includes a SparkFun RedBoard Qwiic. At the heart of each is the ATmega328p microcontroller, giving both the same functionality underneath the hood. Both development boards are capable of taking inputs (such as the push of a button or a reading from a light sensor) and interpreting that information to control various outputs (like a blinking LED light or an electric motor). And much, much more!

Revision Changes: With this revision of the SparkFun Inventor's Kit from v4.1 to v4.1.2, we have swapped out the Carrying Case - Black HDPE with a new SparkFun Carrying Case.

Note: The Arduino Uno version of the kit does not include a carrying case or printed copy of this manual to decrease weight and cost for international shipping.
Note: You can complete all 16 experiments in this guide with either kit.
