Hello All,
I'm looking for a circuit that latches it's output at logic '1' when a negative going pulse is inputted.
This circuit will be used to stop a counter when an object exits a optical sensor.
It should hold it's output high state until a reset button is pressed. (regardless of any further objects that enter/exit the sensor)
Can I use a flip flop for this?
If anyone can help, I would be very grateful.
