UNO R3 Board Project Smart Robot Car Kit V4 for Arduino Learner

Good quality.

Very useful kit for kids, who likes Robotics and basic coding.

Very good quality, my son 11 years enjoyed it a lot. Recommend it highly

I recently purchased the Elegoo Smart Car V4 with Camera from amazon website as a gift for my son.L as it's a wonderful educational tool and a great introduction to robotics. Unfortunately, our experience has been disappointing due to a faulty Ultrasonic Sensor. Despite following the assembly instructions and troubleshooting steps carefully, the sensor does not function at all. This has halted our progress and taken away from what was supposed to be a fun and inspiring learning experience for my son. I am kindly requesting a replacement for the defective Ultrasonic Sensor so we can get the Smart Car fully operational. I hope this issue can be resolved quickly. Thank you for your attention, and I look forward to your support.

Good deal

Received as described. Excellent product, items quality is excellent, I have assembled it with my 12 years old son. He enjoyed a lot. It worked perfectly after Assembly. This product is worth for money. Highly recommended.

Good for kids

The base/top plates are sturdy, even though they are plastic. Instructions are clear enough to understand and assemble. The UNO comes pre-programmed. So once you assemble it, you can start using it like a toy. App control is seamless. All default functions work well. I haven't figured out yet how to customize the programming, for example, do various other computer vision tasks.

An impressive work combining different solutions to real-world problems! The Smart Car has features like: Ultrasonic Range finder for collision avoidance and semi-autonomous navigation; Optical sensors for line following navigation; Bluetooth connection for remote control operation; and an Infrared Remote Control. All these modes of operations work flawlessly except the IR sensor. In my opinion, this is not Elegoo’s fault. However, the engineers at Elegoo could have evaluated the performance of the IR sensor and could have removed it from the kit as the Bluetooth function is enough for manual control. IR remote control operates in the infrared range just below the red end of the visible spectrum. It works in a line-of-sight that will easily be obstructed by nearby objects. It also suffers from interference from other IR devices in the vicinity. For these reasons, IR is not a good device for non-stationary devices. Likewise, the built-in IR works intermittently while the Smart Car is in motion. Elegoo has also provided a smartphone app for both Android and IOS platforms. You can also create your own “DIY Control” remote app, which I like it so much that you have the freedom to program the remote control that suits your need. Overall, I gave this Smart Car a five-star rating. It is a great kit for DIY projects and also for Smart Car base code development exercises. All you need is to assemble the kit, download the Arduino sketches from the Elegoo's website, and use the Elegoo App to control the Smart Car. Most importantly. Have fun with modifying the codes and eventually develop your own code. So far, I have modified the carSpeed and ultrasonic range to suit my interest. I have also added RGB status indicator light, and I have also added a second infrared sensor. Most of the Arduino GPIO pins are occupied but there are few open pins like A0, A1, A2, and A3. So, I have used A0-A2 for the RGB LED light and pin A3 for the second IR sensor. FYI, the built-in IR sensor is connected to PIN 12 so you can change it to A3 on the Arduino sketch and connect a new IR sensor to PIN A3. I am also working on adding a piezo speaker; however, the Smart Car is using both the timers of Arduino UNO and I need Timer2– for functions like tone(), notone(). So, I might probably change the Arduino UNO with Arduino MEGA and add more features to the Smart Car. In conclusion, the Elegoo Smart Car is an excellent engineering toy for all levels. Have fun and try to modify the codes and the hardware to match your own needs. FIVE STARS!

A mi hijo de 12 años le encanto, facil de armar, instrucciones adecuadas.. Solo una queja hay una parte donde se aflojan los tornillos

Muy contenta con la compra, llegó en excelente estado, gracias.
