To my understanding, the RCX uses pulse width modulation to actually
control motor speed, so I'm thinking the first thing you'd need is a
capacitor to even out an RCX output to a level voltage, then an ADC to
convert that into a digital signal, and a demux to take that digital
signal to address any one of several individual devices.

IMHO, it would be much simpler and precise to measure directly pulse width
instead of voltage, that could be done easily with a small microcontroller...

(...) Close. What I would actually be wanting is eomthing that could use the voltage level being output from a *SINGLE* RCX port to do the addressing. So for controlling up to four devices from one port, for example, would require that 25% power to (...) (21 years ago, 15-Jun-03, to lugnet.technic, lugnet.robotics)
