Arduino interfaces Processing

hi friends, am new to this platform and would like to know if (1) processing code can be embeded into the arduino harware and (2) can arduino read data from processing programs?

(1) I am not sure what you mean by that. The c language for the Arduino is quite similar to Processing, though.
(2) Using the serial port you can transfer data to and from Processing.

processing code runs on the PC (MAC LINUX)
Arduino has its own code

the syntax and structure look similar but there are also fundamental differences
