Hi, With only 3 input and 3 output ports, the RCX becomes quite limiting after a while. There are several different solutions to this at various sites. Does anyone know which one is the best out of all of them. I basically looking for good (...) (24 years ago, 7-Jul-00, to lugnet.robotics, lugnet.robotics.rcx)

Sure you can try using just three input/output ports, but eventually you end up scaling back you designs. Of course, you can always buy another RCX to increase the number of ports, which will throw you back $200. Adding a multiplexor is such an easy (...)

You could use the sensors that came with the Cybermaster kit, they have a built-in resistor so it should be possible to hook up two of those on one input port and by using RAW values see which switch is pressed.
