LM393 is a comparator and can not be used as a light metering cell.
Ofcource you can use photosensitive resistor and make your own library to read analog signal from resistor and interpret these data into LUX, but it is another project :)
yes, there are 6 buttons, two on the other side of the PCB.
I'm glad that the project is come useful for you.
Looks like we are talking about different BH1750 libraries, try this one: https://github.com/claws/BH1750
