Error in reading the LDR value from UNO READ component

Hi all,

I am relatively new to grasshopper, and I am trying to use the firfly plugin to read the analog values of the LDR from an arduino UNO. I have set up my defenition to do so and my sketch with IDE is just fine. I am getting sensible data in the serial port. However, the UNO READ is having trouble and inspite of setting up the right port, the output is not being obtained.

This the message from the UNO READ Component:

"1. Solution exception:Conversion from string "319
320
320
320
320
320
32" to type 'Integer' is not valid."

I have attached my sketch also with this, please guide me. This seems to be something very basic but i'm somehow not at all able to resolve.

Thanks,Cheers!!!!
