Hi David
I'm sure it's easier than I'm making it.
Really, I just need to turn the data from the arduino into usable floats. Right now it's coming in as ascii characters and I'm building lists between carriage returns. Hopefully I can now turn those lists into numbers without too much trouble. Should I maybe be doing this with binary numbers? Would that be easier?

Hi Daffydd,
I don't recall having too much trouble transferring bytes from an Arduino over to [comport].
Do you not have any data flowing between the two, or is your concern more about how numeric figures are to be formatted?

Hey Hans-Christoph
Actually, I've had the sensor working with Arduino and pulsing LEDs for a while - that part's fine. Now it's just getting Pd to understand Arduino's Serial.println that's giving me trouble. I'm going to open up [arduino] and I bet I'll find the secret there.
I was hoping there's be a strictly Pd way to do it - it's for an intro workshop and I was going to show folks how super-easy it is. Hopefully I'll be able to show folks how almost super-easy it is instead.
This may be one of those rare occasions where it's actually easier to do something _without_ Pd:)

It wouldn't be so hard, but you'd need some arduino programming experience. If you want something like that sensor that is really easy to use, get a Maxbotix, you can just hook them up to an analog pin and read them immediately with Pduino:

Thanks Hans-Christoph
In over my head again.

I think that is one of the sensors where you have to do the triggering and pulseIn measurement yourself. There are examples on the arduino forum of firmwares that do this, then if you combine such a firmware with the Firmata Arduino library, then you'll have a firmware that will work with Pduino and that sensor.

Hi folks
I'm wondering if anybody can point me at an example of using Pduino and an SRF05 ultrasonic ranger? Not sure how to get the microsecond intervals needed. Apologies if this is covered elsewhere on the list or if it's just a stupid question.
cheers dafydd
