I tried all the examples (the basic examples ) using analog input with potentiometer, even changed to a resistor but none of them worked, the serial monitor always show 1023, and in other examples using leds, the potentiometer doesn't change led brightness. Sorry for my bad english.

None of the Analog Read Examples are working with 2560

But the serial always showed 1023,

From that code?
Really?
