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 analog 2, 3 and 4, the values stay the same.
I get something like 48, 254 and 51. Has anyone had similar problems? I'm
no EE, so my circuit knowledge is limited but I was wondering if I should
replace some of the chips that might have been burned out. I not sure
where to start.

| 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 (...) (28 years ago, 26-Mar-97, to lugnet.robotics.handyboard)
