Hello,
we are using Lego reflectance sensors for an experiment and the HB is
showing a rather strange behavior. If we plug a single sensor in the
expansion board, it works fine, but when two of them are connected, then
none of them work. Even more, if the single sensor reading is 200 decreases over
185 when the second one is connected, without any change in sensor position. We
tried the 4 lego sensor inputs and nothing changes. We are
sure that it is not a sensor problem, but what is it then? any idea?
thanks!
