i can’t find ldr sensor lm393
Enter “LDR” in the parts search for the core library. One of the results is “Photocell (LDR)”. A generic LDR. Fill the part number in inspector if you want it to be an lm393 in your sketch.
Or you can do a google search of the form “fritzing part ldr lm393 module” which turns up this previous query and answer in the forums
which may do what you need.
