I'm working on ways to control more sensors both with and without
using the output port but I have not had the time to work on it very much.
I just got in some extra sensors last week so I can play with them!

| (...) Hang on - if you use all 3 outputs to control the MUX (which leaves me wondering why you'd bother - trees falling in forests and all that) you can get 24 inputs, even if you only treat each output as binary. More plausibly, you can use 2 (...) (26 years ago, 11-Nov-98, to lugnet.robotics)
