Hello,
Im having problems with my circuit, I am using a quad comparator IC (LM339N) but for some reason the output its generating does not seem to change with either changing inverting or non inverting inputs.
I mean, the output, remains same even when the non inverting input (+) is less than, inverting one.
the reference voltage, is inverting one, which I have grounded(also pin12 grounded with it), and with supplying VCC to +ve one(non inverting) , and to Pin 3 of the LM339.
Please Help !
