Hi all,
as a newbie I have a problem in the training center with
my new 1.5 RIS.
The lightsensor shows only a range of 37/47 in view-mode between black and
white. (and so it doesn´t beep)
Is this normal or due to a msfunction of the sensor ?

However this is not satisfying at all because the sensors dynamic range is to low for reasonable applications. Is there someone (...) (21 years ago, 4-Jan-04, to lugnet.robotics.rcx)
