How to get sensor value from arduino UNO to thunkable

Hi, I’m trying to bring data from arduino sensor to thunkable. But I have no idea what kind of value is in the data block. Please answer if you know any solution!

I’m guessing here but a byte array sounds like a list. So you may have to use the list blocks to access that data.
