I will keep this question open and check whether a new IC will fix the problem. The comparator does note it is the LMP however, but I might have mistaken which side was “up”. I’ve tried wiring up the digital ports to the input pins of the comparator, but that shows no decent results. If I connect a led to the output, I see a faint light with a Ohm resistor, while the same led on 5V input shows full brightness.
Information on the LM393 Comparator Chip for Use in Robotic Circuits
I have 5v datasheeg the Arduino running to Vcc of the comparator and the ground of the comparator running to the Arduino ground.
Since the LM comparator chip is too small for an indication of the pins to be printed, the datasheet has an illustrated figure, a pinout, which shows the location and function of each pin.

On all other products, production processing does not necessarily include testing of all parameters.
The 1K resistor is not necessary and you could connect it directly to the Arduino but it shouldn’t hurt operation either so you can leave it there. In the OP, there was no specification of exactly what the datwsheet were, and for all one knows the inputs were so close together that the comparator was responding to thermal drifts.
Limited Engineering samples available Preview: Production processing does not necessarily include. Datasgeet LM can accept inputs down to the negative rail and a bit beyond. I placed a 1K resistor between Vcc and output. Terry Ratasheet is a fourth year mechanical engineering student at the University of Alberta.

Is it required to use all the ports on the comparator for it to work? Product is in design feasibility stage. If you enable the internal pull-up in ,m393p Arduino it should work as that will pull the signal high when the LM is not conducting.
Introduction to comparators, their parameters and basic applications.
Update Made some new observations.
