[SOLVED]LM324N problem!
Hey all!
Since this is my first post i should introduce myself..
My name Karan and i am an engineering student.
I have been working on a project on a project that requires a comparator.
I am using LM324n as a comparator and the circuit is working correctly.
I am using a +5V supply power to the ic but when the output is high i get around 2.1V on the output pin,which is enough to drive an LED but i want to give this output to a PIC18F4520 which will not identify 2.1V as high.
What do i do?
I have tried using a 12V supply for the IC also without any change.
I've been at it for some time and need some help...
