Hi I've gone through and downloaded the firmata and pduino and a few things from the playground on the arduino webpage, but I'm not exactly sure what to do in order to get the arduino working. I've also installed the hardware and everything.
On the arduino-test.pd the [arduino 1] object is coming up as an invalid object.

What do i have to do to get pd to read the arduino inputs?

Thanks.

instead of uploading StandardFirmata, try uploading StandardFirmataV_02. it worked for me and I had the same problem

arduino-test.pd and arduino.pd are in the same folder?!

I'm having this problem right now... installed Pduino and uploaded Standard Firmata to my Arduino, but the Arduino object in PD is invalid. Any ideas?

got it!
you need to copy Arduino.pd and ArduinoHelp.pd files into the /Library/PD folder located in your home directory. Then it will appear as a valid object.
