more sensors in Arduino to Pure Data

Projects Interfacing w/ Software on the Computer

Hi,
I'm a noob in Arduino... I'm trying to link Arduino to Puredata. But:

  • using the object "comport" I can read ONE sensor. How I can use more sensors? (using split (puredata) and map (arduino) I obtain strange values..)
  • Using firmadata library I load "standardFirmata" sketch in arduino, but nothing happen in Arduino-test.pd. I opened the right port, but how I have to use this patch? If I link an analog sensor in A0 pin how I should set the patch? If I press all puts output the arduino board links, but that's it. No other value arrives from the sensor.
    If I use sensors that use digital pin (for example a proximity sensor HC-SR04), how I should set the arduino sketch, to read the echo values in the Arduino--test.pd?

=( Help me...
Thank you!
