As you can tell from my question I am a real newbie amateur but could someone please take the time to explain why the attached voltage comparator actually.
I have simulated it on LTSpice and built it and it does work.
I am confused as to why the LED lights up as it seems to have 2 Positive inputs one from the OpAmp and one from the power supply.
What am I missing and if possible in baby language please,
Thanks hoping some kind soul can explain.
PS tried to upload the LTSpice file but get an error" there was a problem uploading your file".
Is there some problem uploading .asc or .jpg files
