I'm new here and am starting up a new project as a member of the R&D engineering department for my company.
Anyway, I'd like to design and build a testing rig, able to push on a button shaped door handle with enough force to open the door to at least 45 degrees from it's closed state, over and over again until the door experiences failure.
I have thought about using pneumatic cylinders with an air regulator, control valve, an Arduino UNO Rev3 board to accomplish the task. I've yet to see how much force I need to open the door, but I believe safety standards requires door opening force to be less than 60 lbf.
So I'd like to know the best way in approaching the programming portion of the Arduino so that it can take into account the number of cycles it has run, display it on a counter, and ensure the cylinder applies the same amount of force each cycle it runs without fail.
Thanks in advance!
