MPU6050 | Basic MPU6050 Arduino sketch of sensor function

I have the following problem. I would like to remove the noise from an IMU sensor. My clue would be a Kalman filter. In the Arduino IDE you could easily implement one via library. Now I would like to solve this by C# directly on the computer but I can't find a library on .NET 4 that works. I tried it with NugetPackages : MathNet. and Emgu.CV. Do you have alternatives that work on .NET 4.0 or do they even work, and if they do, does anyone have a good example? Have a nice day :)

EDIT: Adding Arduino IDE code

I am trying to load a JSON file into a DataFrame, I know this question was answered multiple times but I've beein trying all the possible solutions but with no success, here is how my JSON file looks like:

I have a ESP32 device sending data at a very fast rate using umqtt module. Also, a Mosquitto broker listening on ports 1883 for mqtt and 9001 for websockets. Finally, a react App showing messages in real-time.

The problem is that every time the React App receives a message from the ESP device, a new TCP connection is established, resulting in a lot of opened connections, as you can see here:

This code is found on how to mechatronics (not mine, https://howtomechatronics.com/projects/diy-arduino-gimbal-self-stabilizing-platform/). I am working on an Arduino gimbal and am using this code. It brings up an error, which I will paste at the bottom. I searched this sort of error and it seems it is because it has an output that is negative but is not defined to come out as negative or may be too large. I am not quite sure what to change or how to change this in order to function. I also have a problem with the yaw motor, which I believe may be fried because my brother connected it to a 12V battery and is only supposed to be 5V. I am sure I can disable the yaw (although not sure if this would solve the other issue) but I don't know which lines to code out in order to do so.

I am developing a project on rpi 0 w and wanted to check out some GitHub code (https://github.com/adamjezek98/MPU6050-ESP8266-MicroPython) for MPU6050 sensor. There is a machine library required. However when I installed it isn't being seen by the Python (3.7).

I'm getting sensor data from the MPU6050 accelerometer. The sensor gives me the acceleration of the x,y, and z axes. I'm currently just trying to graph the x acceleration vs time. Ideally, I would graph them all together but I can't make the single x data vs time graph work, so I'm just focusing on that now. My code is as follows:

I have an arduino program that runs a servo when it's at an odd angle, but after five seconds if still at that odd angle set it as the new center. the problem is that for some reason when I'm setting the angles of the current rotation to be the new center, the values get mixed up. Furthermore, the values of the center seem to be updating before the five seconds has even passed. I think this is something to do with the compiler. My code is here:

during compilation I get a 'multiple definition' error and when I add 'extern' keywords in my hpp file, I get other errors. main.cpp

I have the objective to have my loop function repeated every 1000ms thanks to the timer_start function.

But everything does not go as planned :

g++ -DDMP_FIFO_RATE=9 -Wall -g -O2 -c -o demo_raw.o demo_raw.cpp demo_raw.cpp: In function ‘int main()’: demo_raw.cpp:66:33: error: invalid use of void expression timer_start(loop(), 1000); ^ make: *** [: demo_raw.o] Error 1

BUILD FAILED (exit value 2, total time: 26s)
