The experiment was fairly successful, I was just wondering though if putting 9v
into a sensor port does it any good. Are their any risks in making such a
connection?

I got a beep when I applied negative current.

Any thoughts?

Another thought on this...  I just remembered an earlier posting I made about
sensing the output of the RC receiver with an RCX.  It uses a micromotor and a
rotation sensor as a "buffer" for the signal.  In this way you can detect both
forward & reverse, as well as in-between speeds using only Lego components.
Here's the link (with pictures):

So, hooking up a couple of these "buffers" (one to the main RC output and one to
the auxillary RC output) and a seperate rotation sensor to the RC steering servo
output, an RCX could decode all three channels from the RC receiver.  (I realize
Mark Bellis' reply inferred this, but I thought the pictures might be useful in
visualizing things a bit more...)

(...) That sounds really great. I think I'll try that, I even have all the parts!! I wanted to be able to sense all seven states, and I didn't really want to use a non-purist solution, so this system is perfect. Now if someone could design a (...) (19 years ago, 11-Apr-05, to lugnet.robotics)
