Is it really necessary to filter my signal, even if my only goal is to count rising/falling flanks? or would the offset voltages ruin my signal and make the arduino think it's a pulse?
And what's the exact use of the comparator?
I tried a couple of pulse counting programs i found on the internet, none of them are working so far... I can't seem to get a pulse acknowledged on the arduino, however when i attach a voltmeter to the signal and turn the weel, i can see a slight change in voltage from 231 mV to 224 mV and back...
Appreciate your help!

P.S. : At first i soldered a wire on to the wrong sensor wire (not signal wire), now i have one on the signal wire too, but the old one on the other wire is still there... Maybe it's reacting as an antenna causing all the filth on my signal?
