I had a general question about logging accelerometer data on the Arduino or any microcontroller.
I had a KXPS5-3157 accelerometer hooked up analog mode to measure z-axis vertical acceleration in a car going over bumps.
My question is that would I have to have an accurate time reference like a real time clock or some piece of code that kept accurate time to plot acceleration G force? Since acceleration is based on time.
I want to get the vertical acceleration of potholes, but to make the data meaningful I want to plot it, but acceleration is based on time, so is it possible to have the Arduino log it with time? Or it doesn't matter?
