I am busy on a physics project, basically I have two switches that are normally closed. The experiment will cause the first switch to open, followed by the second one. I need to time the interval between the opening of the two switches.
I am thinking about a 555 timer clocking into a binary counter, would it work? or is there a easier method?
the more accurate the better, umm its a project to measure gravitational acceleration, so a 50ms resolution would be the best. and if i could use a counter the project would be more impressive, since the funds are not limited
