I am trying to measure the force of the impact of an object dropped on a force sensitive resistor https://www.sparkfun.com/products/9376
I used an ardunio uno and the code provided on this site. https://learn.sparkfun.com/tutorials/fo ... ino-sketch
I modified the sketch to sample (loop) once every 2 milliseconds and to store the maximum force measured. When I cranked it down to once every 1 millisecond, the maximum results became flaky.
We accurately measured the height of release of the object to attempt to be consistent.
Results are all over the place.
So, is a 2millisecond sampling rate to slow to accurately capture an instantaneous impact?
Any suggestions on how to make this work?
Thank you.
