Hello folks,
Is it normal to get invalid 'active' signals from the analog inputs
every so often? I have made a lego buggy which seeks out its way from a
darkish room into another room and to a window using a light sensor
mounted on a sweeping servo and avoiding walls using ir sensors. Every
so often light will be detect where there isnt any and the same with a
wall! these random incorrect readings even occur when the sensor is
removed! I am using mostly 'closed-loop feedback' control with some
'sanity checks' to overcome the errors, but is it normal?
Thanks in advance,
___ IAN
