ELEGOOUNO R3 Project Most Complete Starter Kit with Tutorial Compatible with Arduino IDE (200+ Components)

I was looking for an Arduino clone starter kit and considered many options. I’m an Electrical Engineer with 15+ years experience designing, manufacturing and testing space flight electrical hardware for satellites. I have a very high standard for quality and was hesitant to purchase this kit due to its low price and my fears that it would be total junk. However, I figured the price was so darn low that even if it turned out to be junk, it wouldn’t be a huge waste. Wow, am I glad I bought this!First, the set arrives in a very useful organizer. I found this to be a really nice feature and helps save time when searching for parts to build each different project.Upon initial inspection, the quality of each component appeared very acceptable. Definitely low-quality parts — as you’d rightfully expect at this price point — but certainly no where near “junk” quality. By low-quality, I’m referring to mostly the solder quality, but also the individual piece-parts used in the assemblies are your standard Chinese low-grade parts. Some soldered parts were installed misaligned and some PCB assemblies still had visible contamination on them from inadequate washing. Again, this is all to be expected at this price point and so far, I was very pleased. The real test is if everything worked...I completed all the tutorials and found the instructions very easy to follow. A CD is included in the kit, which supposedly contains all the required software, tutorials and datasheets. My laptop doesn’t have a CD ROM drive so I downloaded everything on the Elegoo website. That’s probably the best option anyway — that way, you know you are using the latest versions of everything. The datasheets were a nice-to-have, although some of them were not as detailed as they should be. Still useful nonetheless. The tutorial manual was clearly written — it’s definitely not poorly translated Chinese-to-English like I expected. It’s entirely written in clear English. In some places, I wish it did a better job explaining the code and syntax, but honestly, that’s something Google can handle. Every tutorial was completed easily and I discovered only one technical mistake: the tutorial on DC motor control omitted a ground jumper between the Arduino board and the breadboard/motor controller board. Consequently, the control signal logic levels were not correctly referenced to the same ground potential on both boards. The motor did not respond correctly at first but some quick troubleshooting lead me to add the ground connection and everything worked flawlessly after that. I’ve tested every component in the kit now and everything works as intended. I’m a little bit surprised at this but very, VERY happy.This kit has been a ton of fun to play with. It’s perfect for anyone wanting to get started with Arduinos. It has so many different cool components that this will keep you entertained and get your creative juices flowing. I highly recommend it!

Studied electronics for 2 years in high school (many years ago) and I consider myself a maker. This kit has a ton of stuff to play around with, and the programing is learnable for someone not that computer literate. I would recommend watching YouTube for any tutorials on programing arduino which should get you on a solid footing, and there are videos covering each of the lessons included in the kit as of 2/5/25. Lot of fun, and opening new worlds!

I'm writing this as someone who has never used an Arduino before and this kit contains everything a person new to Arduino could ever ask for! The plethora of sensors and modules kept me entertained ever since I've received my kit and I highly recommend this to anyone ambitious enough to learn something new. Note I say "ambitious" since the provided lessons are more or less just demos to what's in the kit and proper research is required for a deeper understanding of what exactly your doing. If you really want to learn how to use the Arduino and its IDE there are lots of videos and websites that likely already have a solution to whatever issues or questions you may have.There were however minor issues with the kit that I can easily overlook, but I thought I should still point them out:- The kit comes with a relay that isn't attached to a PCB and because of that it doesn't exactly fit on the bread board. This wouldn't have been a huge issue since I thought I could use the wires with female headers, but the pins on the relay are too short and thin for a secure connection. However, what I found entertaining was that the lessons provided recommended that I bend one of the pins of the relay in order to use it with the breadboard. I did exactly that and the relay did fit on the breadboard, but it now also has a crooked pin.- This is most likely a issue with my package, but the case came with a small crack on on of the corners of the lid. This might be due to shipping, but none of the components seemed to be damaged so I guess the case did its job protecting the items.- The included jumper wires aren't the best quality and as when I'm writing this review I've broken the tips of 3 wires already. However they do their job of being wires just fine and I can always get replacements or just use actual wires with the ends striped off.- The included 9V battery actually contains lead which is actually considered hazardous waste so it'll be inconvenient when I need to properly dispose of it.Overall this is a great kit to start learning and experimenting with an Arduino and the amount of things you get is definitely worth the price. If Elegoo does decide to refresh this kit I would recommend replacing the included disk with something such as a USB flash drive since most modern computers no longer come with a DVD drive (Note: the lessons, documentation, and libraries for this kit is available for download on Elegoo's website which is what I used).

This starter kit is perfect for beginners and advanced users looking to dive into Arduino programming and electronics. With over 200 components, including sensors, motors, and an LCD display, it provides everything needed for hands-on learning and experimentation. The included tutorial is well-structured, with clear instructions and code examples that make it easy to follow along. All components are neatly packaged, and the quality is impressive for the price. Whether you're a student, hobbyist, or educator, this kit offers endless opportunities to explore coding and circuit design. It’s a fantastic value for the amount of materials and educational content included.

Good value kit. Quality kit.Economical, low cost set for experimentation and play.Not a robust industrial use item, but minimal investment and cost if a part breaks or something goes wrong.Can use without fear of costly losses.

Good for beginner use, No prior knowledge once you learn to add libraries and input the code it is fun to use.

Full of many projects to get you started in the world of Arduino.. Every kid and adult should have one! I started with one of these kits now I'm making stuff from scratch with the knowledge I gained from the kit!Heres a pic of my latest Arduino project.
