@harri_son It would be helpful to know your background, especially how many years of software development experience you have and in what languages and fields.
The second thing is, what is this project for, your Job, school exercise, or some hobby-related purpose?
By knowing these things, we can better address your issues.
Arduino says and I agree, in general, the const keyword is preferred for defining constants and should be used instead of #define

The serial monitor output is attached. I want to do the FFT of the data, but I don't know the "t" to use. Whether from the timestamp (the laptop time) or I should use Serial.print(micros());
The timestamp is attached below.
09:50:36.276 -> 0.39,-0.23,9.45 09:50:36.276 -> 0.55,-0.39,9.37 09:50:36.276 -> 0.62,-0.31,9.53 09:50:36.276 -> 0.39,-0.39,9.53 09:50:36.276 -> 0.78,-0.47,9.45 09:50:36.276 -> 0.55,-0.16,9.30 09:50:36.276 -> 0.55,-0.31,9.45 09:50:36.276 -> 0.55,-0.23,9.30The Serial.print(micros()) is attached below.
73119143,0.62,-0.31,9.37 73119859,0.55,0.00,9.69 73120559,0.47,-0.31,9.37 73121288,0.78,-0.39,9.37 73122010,0.39,-0.23,9.61 73122727,0.55,-0.31,9.30 73123452,0.55,-0.31,9.37 73124179,0.55,-0.39,9.61 73124895,0.55,-0.39,9.53 73125617,0.62,-0.23,9.61 73126342,0.47,-0.16,9.37 73127062,0.39,-0.16,9.22
You'll have to use micros() for timing, the timestamps you show are inserted by the IDE onto the serial output and are not available to your sketch.
Experience is what you get when you don't get what you want.
