[MOVED] analog input from sensor

[Bhuvanesh123]

i have pir sensor it gives some output voltage with respect to sottunding

if i activate my internal pull down resistor of my analog input pin i am getting correct digital values
if i activate my internal pull up resistor of my analog input pin i am getting no values values(digital value as 0)

Re: analog input from sensor

Usually neither pull-up nor pull-down would be activated for pins configured as analog input. At first sight, you may have misunderstood the configuration options.

By the way, which processor are you talking about?
