  multiplex 2 touch sensors on a single RCX port
 
I have these 2 touch sensors multiplexing on the same input port. Their raw values are 47 and 39. I tried to set up 2 separate events, one for the range of 45 to 50 and another one for 35 to 40. However, the one for the lower feedback often set off (...) (18 years ago, 2-Jun-08, to lugnet.robotics.rcx.robolab)
