Hey there! I've never seen a ping sensor with only 3 wires before. Are you sure there are not 4? If not, let me know the model number and i'll see if i can whip up a driver for you.
So it looks like Parallax has changed their PING))) sensor to have a 3 pin interface, I believe the SIG pin does the transmitting waits for a certain period and receives the Echo on the same pin. Dang, after all these years they have finally went to a standard 3 pin design but still haven't added analog out....grrrrr...Bad Parallax...bad!
If anyone wants to use ultrasonics I'd recommend, ironically enough, the MaxSonar EZ series by MaxBotix they can do analog or digital readouts and they are less of a cost than the PING))) and they are also a smaller form factor, seriously use an EZ-0 with the EZ-B, they are sweet!
Hi, How did you end up connecting the MaxBotix sensor, via the ADC or Pulse timing? I have several from another project that I would like to use. Thanks.
Looks like I'm going to have to build support for the 3 wire ping sensor. Good idea, don't know why they didn't think of it sooner! More ping, less i/o! *eek*
Hi, Thanks for the info. I have it setup and working. I'm new to EZ-B, how do you add the Maxbotix sensor to the Ping Distance built in controls? The existing control only allos the digital interface of the Ping style detectors. Thanks, Nelson
Connect the AN (analog output) from the Maxsonar to one of the 8 ADC inputs of the EZ-B. You can then use an ADC control (or the sharp IR radar control) with it
It MIGHT just work! I'd have to look at my code and see what kind of magical spell I put on that function. Darn assembly It's harder to read then it is to write!
Well that isn't very helpful information from Canada Post, is it? Hmm!! Can you send me a message (from the FAQ page) with your shipment tracking number and I'll get hold of Canada Post and see what's up?

Maybe there are some issues at customs in Holland? You can use the tracking number again your local mail service. You can even phone your mail service and provide them with that tracking number.
Hey Lyron, Canada Post had a huge strike awhile back. It might have delayed your package about a week or so. Either way I hope you have your EZB by now.
on the maxsonar you can hook it up as HC-SR04 OR SRF04 USING ECHO AND TRIGGER ON THE MAXSONAR TRIGGER IS RX PIN AND ECHO IS THE PW PIN no conversion is needed like in analog mode,also analog mode jumps aroung alot and not always steady and its great for robot eyes dual ultrasonic sensors dont fit well in most robotic toys eyes but a single transmitt and receive ultrasonic sonar can
another thing about using the maxsonar it using very low current ,not like the hc-sr04 or parallax does ,2ma compare to 30-35ma on parallax ping so battery will last a lot longer cost it lower too $25 compare to $30

When i try to input the item number, it wont work so i guess i'll have to call them
Since the IR sensor is discontinued, what would be the best place to add this ping sensor, without making, lets say a wall-e look weird.....
thanks,
Carlos.
And i know what happened to the shipment, it was sent by boat in stead of airmail.
USING ECHO AND TRIGGER
ON THE MAXSONAR TRIGGER IS RX PIN
AND ECHO IS THE PW PIN
no conversion is needed like in analog mode,also analog mode jumps aroung alot and not always steady and its great for robot eyes
dual ultrasonic sensors dont fit well in most robotic toys eyes
but a single transmitt and receive ultrasonic sonar can
another thing about using the maxsonar it using very low current ,not like the hc-sr04 or parallax does ,2ma compare to 30-35ma on parallax ping

cost it lower too $25 compare to $30
