liudr:
You don't assemble a message as you print it out, you assemble the message, then print it out.
That makes a lot of sense and thanks for the link.
I don't need my code to look like a pro did it, but I would like to try and keep it clean and tidy.
So wouldn't this be just as good, or I take it that sprintf as you showed is faster?
string S = "this"+"that";
Serial.print(S):
Thanks guys for the tips.
