Polaroid Sonar
Hi Everyone,
I just can't help but believe that some of you have an answer or to, to
the Polaroid 6500 sonar questions asked a few days ago - and so I must ask
them again:
-- What kind of ouput does the 6500 ranging module produce? Proportional
resistance or voltage?
-- Will I be able to take distance measurements to within +/- 1/8 inch?
I sure would appreciate any help,
Tim

Comments
me and connected it to an oscilloscope I received a clocked input that
varied faster or slower depending on the distance of an object in front of
the sensor, but bear in mind that I've no experience of oscilloscopes and
the one I used is waiting to go off for calibration coz it fell of the back
of a landrover (no that does not mean its stolen, it really did fall off the
landrover) but it did appear to clock at + & - 5v, if you have anyway of
confirming this I would, like I say I don't have any experience at using Osc
and this one does appear damaged.
hope this helps
John

Thanks so much for taking the time to put the 6500 module on the scope!
I guess what you describe as the output, is something like I expected, but
that doesn't add up in my mind with using the RCTIME command to read it on
the BS2 end. That's why I wondered if the output was a resistance
proportional to the distance measurement. Can you explain why the RCTIME
command works to read this type of signal?
Sorry to hear about the oscilloscope damage - that hurts.
Thanks again and yes, that does help.
Tim

My stamp manual version 1.9 states that RCtime can also be used as a very
precise stopwatch.
I believe this is the manner which it is used with the sonar application

I should try to answer your question!
Rctime waits(and counts) for a change of state(0 to 1 etc) much as the
pulsin function does.
good luck,
Steve

to find a way to read the output from the 6500 board then use this info to
send commands to the PAK VIII that I'm using to drive my servos. I think
'Sargent' explained the RCTime command to a 'T'. Anyway good luck hope
between the replies you've had regarding the Polaroid Sonar board you get
your project up and running.
