[PD] Pduino&Ping ultrasonic sensor&arduino

Hi Marius,
you are absolutely right! After writing code for the arduino I can use the Ping sensor without any problems within PD (using the PD_inputs_to_PD patch). 
But that is not my problem. My problem is that if I work like that, I have to change the arduino code all the time I change my sensor setup. Like for instance: First I write arduino code for 3 Ping sensors and 3 solar panles...but then I want to use 4 Ping sensors with let's say 3 LEds.
It would be great if I could do all that using only the arduino patch in PD, without writing new code for arduino all the time. Of course after uploading the Pd_firmware onto the arduino-board.
Any idea how? And at the moment I would like to work with 8 Ping sensors :-) and 5 solar panels at the same time.


hmm, I think arduino can handle the ping range finder. but you need to 
write your specific code.
use a code that you find online (the routine is something like: turn pin 
to outlet, set pin high, wait some milliseconds, set pin low, turn pin 
to inlet, measure the time until you receive the echo...)
and then send the value to pd via serial port (115200).
then measure next value.
I think, you should be able to send at least 20 values per second, but 
that is a guess.
do you need more info for the arduino code? how many sensors do you have?

it is

arduino all the time. Well, guess this was the original idea of Pduino anyways
