i was playing around with sloted optical switch, just a normal standard type.
i was trying to know exactly its output and if that i can connect it directly to a pic digital input.
i wired the circuit in a simple manner ( attached ) to a 25Hz source (rotating wheel with holes connected to a motor)
and when i connected a ociloscope to the signal out (channel A, blue) and ground (channel B, Red)
i noticed a strange behaviour the pulses from the signal out is ranging from -1v to 5.5v and the ground seems to be an inverse of it
now is that a normal behaviour ? and why ?
can this be connected to a pic directly or some sort of 555 or similar will be better in between ?
thanks
