for school I want to make a little thing that measures your walking pace (like the frequency). we have an FSR which you stick under your foot so it measures if you take a step. we tried this and it works, by tweaking the threshold. so if the output value of the FSR exceeds 400, it means you are standing on the FSR (e.g. your taking a step). now our only problem is that we don't know how (and if) we are able to let the arduino measure the time between steps, and compute that into a frequency.
can anyone help us with the code??
