Customer Comments

  • Hi folks!

    The Minnesota CoderDojo group has been using the SparkFun Inventor’s kit for about a year now. We are very happy with the SIK and the instruction booklets that they come with are top-notch. I am starting to write a blog on some the things I have learned and I would like to share experiences with others.

    One of my first findings is that the kids LOVE circuit lab #12 (driving the DC motors) however over time the leads on most of the motors have broken off. I have a post on how to fix them here:

    Motors for Arduino Labs.

    I have also added a new lab that allows the students to change the direction of the motors. This helps them with the future robot labs.

    • Hi Dan - Looks like you’ve got an old blogspot URL there? For those looking for the Motors for Arduino Labs post, check out: the corrected link :)

  • I’d like to suggest an improvement to the SIK: please use 1/4W resistors, not the 1/8W ones as currently. The latter are spindly and often very difficult to insert into the breadboard. The cost to beef up the leads can’t be more than a nickel or a dime. Otherwise, the SIK is very useful, particularly with the updated and improved handbook and code examples. Thanks!

  • Sparkfun I love you, when I thought “SIK” could not be better improve it, will be great to use with students :)

  • Just received the kit, very neat, but please correct me if I am wrong, but are there two errors in circuit 3?

    Error in book - instructs you to hook up a red jumper between the 5v on the redboard and the + rail. But nothing is connected to this rail at all, and circuit works the same without this jumper. Any reason for this wire in the diagram?

    Error in code - The code sets up a global constant called DISPLAY_TIME like below, but then never references this again, only using hardcoded delays of 1000 and 10 throughout

    / This variable controls how fast we loop through the colors. // (Try changing this to make the fading faster or slower.)

    int DISPLAY_TIME = 100;

    Please let me know if I am missing anything here.

    Thank You

  • As Member #582128 stated in the reviews, I would love to see this product developed or forked into a classroom version that includes a Student Kit and an Instructor Kit. The Instructor Kit could have more curriculum ideas, slides, examples, concept check questions, etc. and the Student Kits could be sold in say sets of four or five. Also the Guides could be formatted so that they can be three-hole-punched or printed in nice color and prepunched. Instructor Guides might have extra teaching notes and/or room to anotate while the Student Guides might have questions and room to record answers or measurements.

    • Check out There is a lot of information there for teachers including curriculum ideas, examples, etc. It is all available for free. We do sell the labpack which is 10 kits designed for classroom use (and has some replacement parts), if you need less than that just buy the individual kits.

  • Any idea when this item will be back in stock?

  • If you’re interested in coding the examples in JavaScript, I’ve created a GitHub project containing each example written in NodeJS using the johnny-five library. Most examples are identical to the exercise in the SIK guide, however I’ve taken a few liberties.

    The Arduino Experimenter’s Guide for NodeJS is another great resource with similar examples, but is not specific to the SIK guide.

    Join us in the johnny-five chat room!

  • Just got this for Christmas, and it took me a little bit to figure this out: Plugging in the RedBoard is not an optional step when setting up the Arduino IDE. The USB port won’t show up otherwise.

  • So… when the page says “White on Black LCD (with headers)” and “The kit does not require any soldering” AND the pictures for Project #15 appear to show the LCD plugged directly into the breadboard… I expected to get an LCD with headers that I can plug right into my breadboard. But that is not the case. My LCD just has solder pads along the edge. Am I misunderstanding something? Or am I missing headers?

    • You should have headers on that - email techsupport@sparkfun with your order number and they should be able to assist you with getting set up wit the proper screen. Sorry about that!

  • One suggestion for improvement: either supply a slightly narrower screwdriver, or screws with a full-width slot rather than standard phillips. Our students had a really hard time assembling the kits with things as supplied; we had to scrounge up a few phillips drivers to get everything put together.

    Edit: just realized that the screwdriver is actually double ended with a Phillips on the other side. Oops

  • Hi, do you have any idea when stocks will become available again?

  • I second the suggestion of going to ¼ watt resistors. My middle schoolers are fairly heavy handed, and their resistors are looking really sad after 9 weeks of use. I eventually encouraged them to “loosen up” the points on the breadboard with a connector wire before putting in the resistor lead.

    Consider some female connecting wires as well, so you can put a little distance between some of the components and the board. It gets a little crowded to use the flex/softpot/etc while it’s stuck in the breadboard. We’ve also had a heck of a time getting the tactile buttons to stay in the breadboard, even after straightening the legs. One press, and they jump out. Any suggestions before I start soldering headers or hookup wire to them?

    Otherwise, the 3.1 kits have been a real blast for the kids! We’ve explored discrete circuits as well as the Arduino controlled circuits. I’ve added a handful of PIR sensors, ultrasonic rangers, hall effect transistors, and infrared transistors to the classroom shared parts box. Soon, I’m going to order a long neopixel strip and cut it into eight-to-ten light segments, add connectors, signal wire resistor, and large capacitor (1000uf) to make them more kid-proof and go further with these kits!

    • Sounds awesome! Glad you are enjoying the kits, we love to hear customer stories. I will look into upgrading the resistors for the kits though. Personally I hate the 1/6W resistors, so I’m with you on that. As for the buttons we don’t really have any other advice. I know we’ve looked into custom buttons that work better, but keep hitting roadblocks. If you find anything out there let us know.

  • Any release date on this? I’m thinking about investing in the kit but should I wait for this one or go ahead and get V3.1?

    • We are currently out of the V3.1 as well… We are actually out of stock on one of the components. Once we get that in we should be building these in though. Hopefully soon!

  • Bonus points for the references (including picture) to the Nintendo Power Glove. My neighbor had that thing and it was AWESOME (didn’t work worth crap, but that’s not the point. It was awesome)!!

Pretty Good kit but need more tools for teachers

I am a pretty experienced EE and so for me teaching these circuits is easy. I give some background, draw a few diagrams, and build the circuit in class and then give them some variations to tinker with for homework. That said for other collegues trying to teach anotehr class who aren’t as experienced are clueless as to what they should do or assign that isnt robotically read out of the sik guide, which the students could do by themselves. It would be cool if you made a Teacher kit and instructions and then a separate student kit and instructions. The teacher one could be more expensive too as it is a 1 time buy, and maybe you could drop the price of the student kit which most teachers buy in bulk anyways.

Nice variety of components & activities...well written circuit exercises

I am teaching an “Introduction to Arduino Programming” class at one of our local ham radio clubs. We have students of all ages & backgrounds participating in our class. I am using the SparkFun RedBoard as the foundation for the class along with an AdaFruit Touch Shield V2 for the display. I purchased several Inventor’s Kits for the students to use in the various “lessons” that I have prepared for their guided learning. The Kits are especially valuable to me because they contain a nice variety of components. The included Guidebook is an excellent complement to the activities that I am having the students perform in the learning process. Those students who complete my “learning exercises” quickly & easily can further their learning by building the circuits in the Guidebook & learning the concepts presented by these as well. Thank you for assembling and offering the Inventor’s Kits for sale !!

The Sparkfun inventor’s kit is a great introduction to Arduino projects and programming. I had some hardware experience (built a CCD camera from a kit a few years back), but I wanted to learn the type of programming involved with this microprocessor. The instruction book + kit makes this very easy and allows for lots of experimentation in both the hardware and software. One component in the kit was faulty, but Sparkfun replaced it quickly with just an email. Highly recommended!

EXACTLY What I Needed!

I’ve never played with electronics much or micro controllers at all. I keep hearing about all of the wonderful projects people are making using the Arduino for prototyping and I wanted to try for myself. Now I have visions of an electronics workbench in my future, So many things I want to try. This is definitely an excellent kit. Wish you would come out with add on kits for it. Expansion sets would be awesome!

Unreadably small print in the book

I’m sure the content is great, but to cram all that content into a relatively small book they used small enough print (often on a grey background) that I find difficult to read even with reading glasses. You’re making me feel old dude…

Eager to get started!

This is a Christmas gift for my pre-engineering teen student, and we’ll be looking forward to digging in after it’s unwrapped Christmas morning! Keep up the great work Sparkfun!

NIceeee !!

… i will use this to teach a high school students !

Invented kit 3.2

After a struggling time with getting the serial drivers, its working fine. I purched it to learn Arduino programming but all the header information does most the work for me. Probabley woulded buy it if I knew this ahead of time.

An incredible introduction to the Arduino

I have to say I loved it. We went through the 10 projects on the file. Each one of them show the wiring in color, in a very clever way to guide a student on making the proper connections. My wife really enjoyed playing with this stuff. She is now setting up a gardening system for their student’s sience fair and also making some changes to introduce Arduino into the Junior High Curricula. Thank you very much for a great and didactic product!

It is for my son.

First, I am thankful the product arrive really quick. It looked complete and in good condition. I am sure it will be enjoyed. Thank you.

Great way to get kids interested in electronics and inventions

I bought the kit for my kids (10 and 8) to try and get them interested in electronics and robotics.

The kit has everything required to build complete projects, beginning to end, and also a full range of projects utilizing a variety of components, from LEDs to motors and display. The guide diagrams are very good in helping children wiring the solutions together. After going through a couple of projects with them, thay started wiring the projects in the book themselves and even learned how to upload the code; they now spend hours wiring and uploading; I believe this experience is both educational and helps them develop problem solving and troubleshooting skills.

Great buy!

It's great!

Enjoying it thoroughly.

About in inventer's kit with Arduino

This kit is a fun return for this retired engineer’s roots of early kit building and experimenting for educational purposes. And I am about to order a Tektronix oscilloscope TBS-1052B-EDU and its associated coursework package. There are many posted lab units that use the Arduino as a signal source and test example. This will replace my 40 year old Heath Kit Oscilloscope that still works but old technology. Thanks to the Denver Post article, that introduced me to Sparkfun. Also have Photon kit on back order.

Still the same crappy buttons...

…when are you going to get breadboard friendly ones?

Very nice kit, one of the best I have had

Hi, everybody!

I am very excited with all kind of experiments can be done with this kit. A very good selection of sensors and actuators. I mounted all the projects and everythihg worked as expected. I loved it, specially the flex sensor, flexible potentiometer, servo and display simple projects.

Congrats for this excellent kit. I was also suroprised by the very fast shipping service. I live in Nicaragua, Central America, and this kit came in a week or so, faster than any other thing I have bought on line ever. Thanks.

Been looking for something like this for years

In the States when I was growing up (80s-90s), nerdy kids were really only presented with Med school and Law school as careers. I totally missed out on engineering. When I discovered computers in graduate school, I really wanted to understand their low level operation and how they could interact with the physical world. This is a perfect kit to get started. My kids will not miss out on engineering like I did.

Best way to learn arduino

Love the redboard enhancements over regular arduino. Great set of components/sensors and excellent manual for all experience levels. If you’re serious about learning arduino skip all the “starter kits” and get this.

Amazing fun

The Kit is a lot of fun and would have given 5 stars if not for malfunctioning RGB led (Green wasn’t lighting up).

Great for beginners!

… because I am one. Great explanations and fun to learn/work with. The Arduino API is also nice, and the content sparkfun has created along with it is also awesome. Just had difficulties in the beginning getting the drivers to work on my Win 8.1. Took me a few good hours, but once it worked… it worked. Thanks, sparkfun! You’ll see more of me.

Best Thinge i bought from this shop

‘Cus it’s the only one I bought.

But it’s still pretty cool

Great learning tool

Easy, well written great starter kit.


My son and I have been working through the labs and they are spot on. I would recommend just putting the importand code commands at the top then all the comments after.

Neat little kit that every inspired inventor should have

This kit is perfect for inspiring young inventors or just someone (me) who wants to build a robot after retiring from the rat race. I had basic understanding of electronics, but this little kit has given me the tools I need to go to the next level.

Well thought out kit. Covers how to configure pins for digital, serial and analog control. Liked the red board and bread board on the mounting plate. Book is well written and illustrated. Over all great.

Now I’m ready to work on the remote semaphore signal project. Can’t wait for the pwm boards to arrive.

Got started at a presentation at Broomfield Library. I am retired and so I have been spending lots of time on the SIK. On Saturdays one of my daughters joins me on the SIK. I have had it for about 3 weeks now. I expect to make another order next week. Will get more parts for ME!!! May get an SIK for a granddaughter and a grandson also, I plan to order a small graphics LCD and other things.

Really fun so far

I’m having a lot of fun with the kit so far. My son and I are playing around with it and really enjoy the exercises. Only bit of advice, the instruction book shows the board and bread board on opposite sides since my Sparkfun label was upside down.

Best Thinge i bought from this shop

‘Cus it’s the only one I bought.

But it’s still pretty cool

compared to

the electronics kit my father bought me in the ‘60’s, this one is a better value. The old one had a greater selection of primary components, one or two transistors (but no IC’s or LED’s) for which the jumpers were secured between the coils of springs.

A Good Addition...

I run a makerspace in Newport, WA. I was looking for something that had good beginner type projects as well as the possibility for growth beyond the book. This kit provides for that and more. The wide range of parts that come in the kit really have our kids thinking outside the box when it comes to projects. Additionally, the RedBoard’s Arduino compatibility allows us to piggyback any standard shield as well as our own circuits on a proto-shield. All in all a great product.

Excellant education gift!

I bought this for my nephew as an educational gift. He was mesmerized by the kit and would not put it down for days. It has definitely provided a spark in is interest in electronics. I could not be more pleased with the kits capabilities.

Great little setup for those just getting started with electronics

Circuit examples are straight forward and easy to follow. One thing that might be cool if the SIK Guidebook linked off to some of the Sparkfun tutorials for those that wanted to go more in depth with the nuts and bolts of things. All and all, a nice quality kit for getting started.
