ELEGOO UNO R3 - Help

[1benyork]

I'm lost. I purchased ELEGOO for a school assignment, successfully built and tested the car. However, I uploaded modified code to the board and have not been able to use the remote control to control the car since. I've tried uploading the the Remote Control code example provided in the Arduino IDE, which continuously fails to compile. I'm at my wits end with this. Anyone know a method to reset this to its out-of-box state?

What was its oob state? If it arrived with working code loaded you'll have to find the source code for that and re-compile that unadulterated version.

Maybe you should post that here, exactly as you're trying to compile, and let someone else try. What error/s do you get- maybe you're missing a library?

Hi beny,

welcome to the arduino-forum.

You are working on a informatic project. And what is needed most in an informatic project is information.
The process to "reset on factory settings" is not as easy as with a consumer-device. It is not done with a 10 seconds long pressing of the reset-button.
There are mutliple ways to get your microcontroller running again. All ways require additional information.

Here is a step by step screenshot tutorial how to post code in an easy to read and easy to copy way

Make experienced users help: two ways to quickly post code as a code-section

Hi newcomer, This thread wants to show you how you can speed-up getting helpful answers with small effort. If you manage at least to post this way. You have the sympathy of the experienced users. If you are willing to invest another 20 minutes these 20 minutes extra-time will save you a minimum of 200 minutes to finish your project. always post your full sketch. As a code-section from the very first to the very last line A code-section has a small height => keeps your posting "short" but…

additionally you should post links to the manuals delivered from elegoo.

Encouring tap on your shoulder: head up! with the support of the forum we will get it up and running. This is just a lack of information and knowledge how to do it.

First step post the informations as described above.

best regards Stefan

Is it an "ELEGOO UNO R3 Project Smart Robot Car Kit V 4.0 (with Camera)"?

Smart Robot Car Kit V4.0 (With Camera)

If it's not that one, find the one you bought.

About 2/3 of the way down the page is a line that says "Description Resource Reviews". Click on "Resource" to see the link to download the "Tutorial and Code". The Arduino sketch for the firmware is in that download.

Thank you for providing the information. I was able to figure it out and create a video for anyone who might experience this in the future.
