Has anyone attempted to mux the three sensor connections to expand the
RCX's sensor capability? Think this is possible?
I don't have an RCX of my own [yet] nor the EE capacity to pull this
off, so I'm counting on the geniuses out there!

| You can: 1. Put multiple Touch sensors on the same input but you can't tell which one was hit. 2. Put a Light and Touch sensor on the same input and read normal light levels except when the Touch is hit it the input will read 100. 3. There are a (...) (26 years ago, 11-Nov-98, to lugnet.robotics)

This could be extended to nine sensors through all three sensor ports. I'm working on ways to control more sensors both (...) (26 years ago, 11-Nov-98, to lugnet.robotics)
