ELEGOO UNO R3 Project The Most Complete Ultimate Starter Kit Compatible with Arduino IDE with Tutorial

Super easy to use, great choice of parts, great quality and the tutorials were great.I had ONE issue: the sound detection module was impossible to calibrate; I couldn't get the pot low enough so even in a quiet room the digital input was stuck at "on". I couldn't find a way to contact the manufacturer to let them know this was defective, perhaps they'll respond to this comment? However, I saw how the operation of the part worked and a replacement will be cheap, so I'm not really bothered.Note that the tutorials are meant to get you acquainted with the components, not be the worlds' most exciting projects. That's ok and actually appropriate: there is so much online to really get you that next step. It's more important that Elegoo give you good quality components, clear spec sheets and a simple "how to use".Some of the tutorials were just the slightest bit confusing on the operation (I wasn't precisely sure how to wire the item), and as such I had to reference the data sheet; for example, the wiring on the PIR wasn't super clear since the project showed the front of the PIR, but the pins were on the back and I connected it backwards. However, this was minimal and actually trained me to read the data sheets, so no harm.In all, very useful.One recommendation: use the Arduino online creator in a browser instead of the IDE on your computer per the instructions. The online creator worked flawlessly (once I installed the required plugin for the browser to communicate to the board for my Mac), and it's super nice to have your sketches in the cloud.I would have liked some MOSFETs in the package - that's all I had to buy on my own, otherwise I had all the parts I needed to do almost any project I want.Next up: protoboards, soldering, and making some projects permanent! (I actually think I'm going to try to buy separate ATMega chips, because that's not very difficult to do.)In all, this kit was all I needed to go from novice to confident. And I'm sure I'll have some of these parts for a long long time, as they're good quality.

The Uno R3 Project Box is a great option for anyone wanting to get into electronics and the Arduino. All of the components seem to be of good quality, although there were two components which had slightly bent pins but nothing that caused a problem and were easily straightened with no negative effect on the component itself.I bought the product with one specific project in mind although now I have all of the components I have thought of plenty of other projects to do.The only very minor issue I have come across so far is that the cd did not read in my drive, but that could well be either a one-off or an issue with my drive. This is not a problem though, as everything on the CD is also provided on the Elegoo website.The PDF guide seems well written and provides enough information to at least get started, covering installing the Arduino IDE, required drivers and connecting the UNO R3 to your PC. In all honesty, I haven't followed through and completed all of the tutorials. That said, having looked through them, they do cover some information that isn't necessarily self-explanatory, such as covering the usage of breadboards, resistors, schematics, wiring diagrams and Pulse Width Modulation. I think it's a good resource that would come in handy for reference should you need it. I would say that whomever wrote the PDF enjoyed doing so and gives a good amount of information on each of the points. It's easy to understand and well-written.Also included on the cd/download are the required libraries for using some of the additional modules and components so you will need to grab them and follow he instructions on the PDF for adding the libraries to your Arduino IDE.As this isn't included in the product listing above, here is a component listComponent listing:-- 5pcs White LED-- 5pcs Yellow LED-- 5pcs Blue LED-- 5pcs Green LED-- 5pcs Red LED-- 1pcs RGB LED-- 5pcs 22pf Ceramic Capacitor-- 5pcs 104 Ceramic Capacitor-- 2pcs Photoresistor-- 1pcs Thermistor-- 5pcs Diode Rectifier (1N4007)-- 2pcs Electrolytic Capacitor (10UF 50V)-- 2pcs Electrolytic Capacitor (100UF 50V)-- 5pcs NPN Transistor (PN2222)-- 5pcs NPN Transistor (S8050)-- 1pcs Tilt Switch-- 5pcs Button (small)-- 1pcs 1 digit 7-segment Display-- 1pcs 4 digit 7-segment Display-- 1pcs Sound Sensor Module-- 1pcs LCD1602 Module ( with pin header)-- 1pcs IC L293D-- 1pcs IC 74HC595-- 1pcs Active Buzzer-- 1pcs Passive Buzzer-- 1pcs RTC Module-- 1pcs DHT11 Temperature and Humidity Module-- 2pcs Potentiometer-- 1pcs Rotary Encoder Module-- 1pcs Joystick Module-- 1pcs Keypad Module-- 1pcs 5V Relay-- 1pcs IR Receiver Module-- 1pcs UNO R3 Controller Board-- 1pcs Breadboard-- 1pcs Servo Motor (SG90)-- 1pcs Stepper Motor-- 1pcs ULN2003 Stepper Motor Driver Board-- 1pcs Prototype Expansion-- 1pcs Power Supply Module-- 1pcs HC-SR501 PIR Motion Sensor-- 1pcs Ultrasonic Sensor-- 1pcs ADXL335 Module-- 1pcs 3V Servo Motor-- 1pcs MAX7219 Module-- 1pcs Remote-- 1pcs 9V 1A Power Supply-- 1pcs 65 Jumper Wire-- 1pcs Water Lever Sensor-- 1pcs USB Cable-- 1pcs 9V Battery with DC-- 1pcs RC522 RFID Module-- 10pcs Resistor (10R)-- 10pcs Resistor (100R)-- 10pcs Resistor (220R)-- 10pcs Resistor (330R)-- 10pcs Resistor (1K)-- 10pcs Resistor (2K)-- 10pcs Resistor (5K1)-- 10pcs Resistor (10K)-- 10pcs Resistor (100K)-- 10pcs Resistor (1M)-- 20pcs Female-to-male Dupont Wire(This list is taken from the Elegoo UNO R3 product page)

Great product - really happy with this purchase. Great introduction to Arduino. The board is fully compatible with the Arduino IDE (I wasn't sure how that would work when purchasing - all works great).The kit comes with a set of tutorials and code samples. Dvd in the box, but I downloaded from their website. We are still running through the lessons - it was easier to get the IDE communicating with the board than I expected.Cord included to connect to the board requires USB A... If you have a modern Mac you may need to get get a USB A to USB C converter.Still loads to learn and experiment with. This kit has been a great way to start out and get some fundamentals figured out... Very happy this is what I chose as a starting point - a solid foundation.

A recommended bit of kit, cheaper than an Arduino but Elegoo have a good reputation as 3rd party manufacturers of Arduino boards under the open source agreement. It is fully compatible with the Arduino Uno.The included kit contains lots of parts to get you started in lots of areas from robotic motors to sensors for all sorts of things and discrete components and breadboards for building the associated electronics.In my kit the RFID module didn't work at all and the 4 digit display had a digit that didn't work. All the parts in the kit were there and individual parts are easily obtainable cheaply on Amazon.having done the 33 lessons which basically illustrate the capabilities of the Elegoo Uno board I now feel ready to take on more advanced projects like those on the official Arduino website.

I bought this as a gift and the recipient really likes it.
