hello, it seems as if i once posted something related to this but i was not really clear.
my ideas with microcontrollers are sometimes limited, please please i really need help.
i am trying to interface the pic16f877a with an input signal that is very very small (about 200mv). i am using an input sensor that sends one pulse of 200mv and goes back to 0v, but i know that the input voltage for digital inputs should be atleast 3v
someone should help me tell how i can exploit this low voltage or how i can even amplify the pulse before using it at the level of the microcontroller. pls
