I have a extremely complicated two polaroid sensor set up going on... I
had a diode connected to each of the ECHO lines so that I can combine the
two lines together... However, no signal passes through this setup...
However, I have validified the fact that they work independently... My
question is Fred or anybody else on this god forsaken planet, can I use
BOTH TIC2 and TIC3 for the sensors??? I would share all of the other
lines except for the ECHO lines... If I can use both of them, what would
be the corresponding addresses that I would need to poke and clear to
make this work??? I have no clue as to where to look up this
information, so I decided to just ask this question... I would
appreciate a speedy response...

| Try connecting a 4.7K pull up resistor to VCC on the ECHO pin before the diode. the echo pin is open collector and pull up is provided by the handy board digital input when used as described in the handy board instruction. When you add the diode (...) (26 years ago, 23-Feb-99, to lugnet.robotics.handyboard)
