Check the blink without delay example to see how to perform an action at every given interval without using delay().

Furthermore, as you can see in the code - I've got the temp, and "deg C" on two different prints, followed by a blank println - how can I get these two little snippets to appear on the same line in the serial monitor, with one line of code. I thought maybe Serial.println(temp, "deg C"); may work, but not so.
Serial.print("This ");
Serial.print("prints on ");
Serial.println("the same line!");
