11.- WriteBytes and WriteStrings.

p110i_UNO_hm10_WriteBytes.aia (199.2 KB)

We convert text list
["65","66","67","68","69","70"]
to number list_n.
[65,66,67,68,69,70]

Send this list_n with "WriteBytes".

We can also send with "WriteStrings".

Notice that WriteStrings adds the NULL character. If you want to avoid it, use the NullTerminateStrings block.
