I am trying to control motor speeds from my iPod through Processing and Arduino but don't know how. I have seen commands on Processing like "arduino.analogWrite(11, 200)". I understand this means write to pin 11 on the arduino analog value of 200. I know how to have a serial communication from Processing to Arduino but need something more specific for variable values.

How do I make the arduino listen to analog values?

Thanks in advance.

I am trying to control the water level in a bathtub using OSCTouch, Processing and Arduino.

I wrote the code for Processing but I am having some trouble with it.

All that is required of the board is to send the a value corresponding to the Fader on my iPod to my Arduino board via serial connection.

Printing water[0] is always 0.

Every time I change the value of the fader I get this message in Proccesing:

Here is the code:

Thanks in Advance,
