That's a lot of cutting and pasting of numbers from the teminal capture file and then you still have to add the "0x" in front of the number to make it a valid Hex value. (see the linked post for details on the whole process) I have a sketch displaying six temps on an lcd, each with it's unique temp label (one , two , etc. because they are on a breadboard so it wouldn't make any sense to name them "inside" or "outside" but I could just as well have made the labels read "Tom" "Dick" "Harry" etc....
