A note for SparkFun Inventor's Kit v4.1 users:
The only change that was made from the SIK v4.1 to the SIK v4.1.2 is our new carrying case. All of the internal parts and instructional guide have remained the same!

The SparkFun Inventor's Kit (SIK) is a great way to get started with programming and hardware interaction with the Arduino programming language. The SIK includes everything you need to complete five overarching projects of 16 interconnected circuits that teach everything from blinking an LED to reading sensors. The culminating project is your very own autonomous robot! No previous programming or electronics experience is required to use this kit.

The full-color, spiral-bound SIK guidebook (included) contains step-by-step instructions with circuit diagrams and hookup tables for building each project and circuit with the included parts. Complete example code is provided, new concepts and components are explained at the point of use, and troubleshooting tips offer assistance if something goes wrong.

The kit does not require soldering and is recommended for beginners ages 10 and up looking for an Arduino starter kit. For the SIK version 4.1 series, we took an entirely different approach to teaching embedded electronics. In previous versions of the SIK, each circuit focused on introducing a new piece of technology. With SIK v4.1.2, components are introduced in the context of the circuit you are building, and each circuit builds upon the last, leading up to a project that incorporates all of the components and concepts introduced throughout the guide. With new parts and a new strategy, even if you've used the SIK before, you're in for a brand-new experience!

The SIK v4.1.2 includes the RedBoard Qwiic which allows you to expand into the SparkFun Qwiic ecosystem after you have become proficient with the SIK circuits. The SparkFun Qwiic Connect System is an ecosystem of I2C sensors, actuators, shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you can’t hook it up wrong. With the addition of the SparkFun RedBoard Qwiic, you will need to download a new driver install that is different from the original SparkFun RedBoard.

Reminds me of math class

The instructions aren’t made for anyone with no experience. The software IDE learning curve is brutally steep. The issue is it’s being presented by ppl that already have mastered this stuff and the basics are no longer on their radar.

They need an absolute beginner to create a video of their experience learning the software set-up and how to navigate and breakdown how to troubleshoot coding, not a seasoned professional.

The hardware is awesome. I’ve gotten past the initial software nightmare, took me a month. Starting to enjoy this thing.

Kids dig it

I've been giving this to 8-10 year old children and with hand holding through the first few circuits they are able to move through the sequence and complete each project on their own, even though they don't understand every word in the book or the code. They've all wanted to build more circuits at the end. Yay to this kit.

Nicely packaged with all components

A few minor disconnects with the documentation such as the location of the sample software but overall a very nice kit.

Very Solid kit

Very solid kit for teaching electronics but not fully kid proof. My son hooked up 1 wire wrong after a week n it fried his Red Board. Disappointed because now I'll need to buy another Red board. UPDATE: Sparkfun offered to help fix my son's red board, so I'm upgrading my ranking to 5 star due to the excellent customer service.

Excellent introduction to arduino!!

I am really enjoying doing electronics by myself. In addition, both SparkFun and the internet provide plenty of support and ideas to develop your invertor mind :-)
