Arduino_Pd
This repository is a set of Pd abstractions (both vanilla and extended) and Arduino code that facilitates the communication between the two platforms.
[serial_print] (and its extended counterpart [serial_print_extended]) works with the Serial.print() and Serial.println() functions of the Arduino.
Even though Pd-extended is not developed or supported in any way any more, I'm still including an extended version of [serial_print] for those who still use this software. This version is in the Pd-extended_version/ directory of this repository.
[serial_write] works with the Serial.write() function of the Arduino.
Check their help patches and Arduino code for more information.

Update December 2015: enabled sending lists including symbols under one tag
Update December 2015: corrected the issue with sending a bang while there is data saved in the abstraction
Update December 2015: enabled the word "float" to be used as a tag in "serial_print_extended" (although it's probably not a good idea to use this word in Pd...)
