Arduino Uno WIFI REV 2

Projects General Guidance
1

I nee assistance and guidance on a project involving the Arduino Uno WiFi Rev 2, with the objective of creating a web server that can display data obtained from the integrated accelerometer and implementing an external SD card module for data storage. The Arduino Uno WiFi Rev 2 is equipped with both an accelerometer and a Wi-Fi module, making it an ideal platform for this project. However, I require assistance with the coding aspects to ensure a successful implementation. Specifically, I am looking for guidance on the following:

  1. Integration of the Accelerometer: I need help with coding to gather data from the integrated accelerometer on the Arduino Uno WiFi Rev 2 and display this information on a web server. This data should be accessible via a web page.
  2. External SD Card Integration: Additionally, I am planning to integrate an external SD card module with the Arduino Uno WiFi Rev 2. The goal is to store the acquired data on the SD card for future reference. I would greatly appreciate guidance on how to set up and code this external SD card module to work seamlessly with the Arduino.
  3. Web Server Implementation: To make the data accessible, I intend to create a web server that displays the accelerometer data in real-time. Any instructions, sample code, or best practices for creating this web server would be highly valuable.

I am aware of the capabilities of the Arduino Uno WiFi Rev 2 and its potential to serve as a versatile IoT platform. However, as I am relatively new to Arduino development, I am seeking expert advice and code examples to ensure the successful execution of this project. Your assistance in providing the necessary guidance, code snippets, or any relevant resources would be greatly appreciated. If there are specific libraries or references I should explore, please kindly share those as well.

Thank you in advance for your support. I look forward to your expert guidance to help me achieve the successful integration of the accelerometer data and the external SD card module with the Arduino Uno WiFi Rev 2 web server.

Most of those items have associated libraries which in turn have examples which you can play with .
Work on a part at a time , then add the next …

If you are new to this , try a few less adventurous projects first to improve your coding .
As you will see people will help you with problems with your code …. So get started !!

The energy is much appreciated,
I started with the examples on the IDe. Multiple sketches began interacting as one, this has been the progression made so far.

Have you done something similar? If so, kindly forward a copy of the sketch.

No I haven’t done anything similar.

That is the code so far. Found out I

error refused
error refused1920×1080 50.9 KB

could use firebase. But an error : connection refused keep holding me down
