Hi Chris, thanks for sharing this. I had the same positive results with reed sensors in my automated rail station. The station actually detects the incoming train through the well known light sensor + lamp method, but I wanted a way to distinguish (...) (25 years ago, 6-Dec-00, to lugnet.trains, lugnet.robotics)

Chris If I understand correctly you can add a series resister to each reed switch using the formula r=2^n*R. Where n is the number of each switch (1,2,3...) and R is some resistence value that is friendly to the RCX. This way you can add several (...)
