Yes, this is possible using the "instrument-control" package

This depends how you send the data from the arduino? Are you using
strings (you convert the integers or double to string before sending) or
are you using some binary communication?

Basically you'll create a serial object, read data into a buffer using
srl_read and then convert them. For binary data there is "typecast".
