[PD] Stupid arduino question

The easy way is to get arduino to send bytes, like:
Serial.print(value, BYTE);
This is fine if the value is between 0 and 255, otherwise you need to send:
, catch the ASCII linefeed (CR = 10 or LF = 13) and accumulate all the 
digits before that, subtract ASCII zero ('0' = 48) from each digit, then 
multiply the digits by powers of 10 and add them together.
