I was aware that IR sensors can only give digital (on/off) information.
Using analog ports will not give you any extra information.
Perhaps the ON voltage level of your circuit is lower that 5V and that
each of your sensor circuits differ in such a way that each ON voltage is
different. That may be why you get constantly the same but different
values.

| Hello to all, I've run into a small problem with my analog ports. I've got 3 IR transmitter/recievers hooked up to 3 ports, and the "levels" that they are reading is stuck. What I mean is that if I print out to the LCD screen the current values of (...) (28 years ago, 25-Mar-97, to lugnet.robotics.handyboard)
