Analog inputs not "working" — I only detect "noise"
Hello Chief Delphi,

Today Team 2502 did a marathon of reading and writing values to Digital inputs and outputs, we blew some air with the pump, and implemented a steering wheel, etc. Our last pit stop was with the analog input.

I opened Analog Input, set the correct slot/channel and when I probed the wire, all I got was near-zero numbers. Things like 0.0001342837 or like -7.001327E23 (Very small numbers)

I'm guessing that something's being read but not the correct values. This happens whether or not we have a sensor plugged in. We've tried numerous jumper positions. What we to simulate a sensor was plug in a 9V battery. Tomorrow we'll try plugging in an actual sensor like ultrasonic (today we couldn't find PWM female-to-female cable so we couldn't plug it in).

Anyone have prelimary guesses?
Thanks,
Keehun
Team 2502
